AMD officially launched the Radeon RX 7800M mobile graphics, which fills the rather vast gap that exists between its flagship Radeon RX 7900M, and the mid-range RX 7600M XT. This is the first official outing of the "Navi 32" GPU on the mobile platform. The RX 7800M maxes out the "Navi 32," enabling all 60 compute units, however, it does not max out the memory bus. The RX 7800M comes with 12 GB of 18 Gbps GDDR6 memory across a 192-bit wide memory bus. This means that only three out of four memory cache dies (MCDs) of the "Navi 32" are enabled, giving the chip 48 MB of Infinity Cache.

The RX 7800M essentially has the GCD core configuration of the desktop RX 7800 XT, but with the memory and cache configuration of the desktop RX 7700 XT. The 60 CU give it 3,840 stream processors, 120 AI accelerators, 60 ray accelerators, 240 TMUs, and 96 ROPs. The GPU comes with a Game Clocks frequency of 2145 MHz, while the memory ticks at 18 Gbps (432 GB/s memory bandwidth). AMD has given the RX 7800M a total graphics power (TGP) value of 180 W, which makes it fit for performance-segment gaming notebooks and mobile workstations. For reference, the RX 7900M comes with a TGP range of 180-200 W.

XFX earlier this month debuted the Phoenix Nirvana line of premium custom-design Radeon RX 7900 series graphics cards with the China-exclusive RX 7900 XTX Phoenix Nirvana. The company is expanding this lineup with two new models, both of which are draped in white. These are the company's first white-themed graphics cards. The lineup now includes the Radeon RX 7800 XT Phoenix Nirvana White, and the RX 7900 GRE Phoenix Nirvana White. Both cards appear to share a common board design, because the compacted "Navi 31" ASIC powering the RX 7900 GRE is pin-compatible with the "Navi 32" ASIC that the RX 7800 XT is based on. Since both GPUs feature a 256-bit GDDR6 memory interface, and a nearly identical typical board power value of around 260 W, AMD's board partners get to use their RX 7800 XT custom board designs for RX 7900 GRE products.

The XFX RX 7900 GRE Phoenix Nirvana White features a significantly different board design to the company's Merc 319 product that's available in the west. The heatsink is noticeably larger, the cooler shroud appears better ventilated, and XFX is using thicker 100 mm fans for higher static pressure than from the ones you find in the global Merc 319 card. The most striking design element of course is its color trim. White makes up the cooler shroud, the fan impellers, and the backplate. The heatsink protrudes out of the edges of the black PCB that's barely noticeable. The card is 33.7 cm long, and 5.9 cm-thick, with a 13.2 cm height. The RX 7900 GRE Phoenix Nirvana White comes with a hearty 6.7% factory overclock, with a 2394 MHz boost clock (vs. 2245 MHz reference); while the RX 7800 XT Phoenix Nirvana White ticks AMD reference 2430 MHz boost. Both these cards, unfortunately, are China-exclusive products, just like the RX 7900 XTX card XFX launched earlier this month.

Vastarmor is a relatively young graphics card manufacturer and AMD board partner (since the RDNA 2 days)—their Alloy product range was updated with new Radeon RX 7800 XT and RX 7700 XT triple-fan "PRO" models last September. VideoCardz has discovered a new dual-fan "non-PRO" white variant—the Vastarmor RX 7700 XT Alloy White 12 GB. TPU's GPU database entry lists a release date of August 25—according to the VideoCardz report, Vastarmor has not settled on final pricing or an official launch date. The standard black (with small red accents) RX 7700 XT Alloy model did reach Chinese retailers last year—the pale variant is predicted to cost about the same, or demand a slight premium over the black version.

Specifications remain consistent across both—according to VideoCardz: "Vastarmor has verified that the card maintains a base clock of 1784 MHz, a game clock of 2276 MHz, and a boost clock that reaches up to 2600 MHz (an overclock of 2.2% for boost). Despite its compact size, measuring at 26.3 x 13.2 cm, the card demands three slots due to its thickness of 5.6 cm. Power-wise, it relies on standard 8-pin power connectors, installed in pairs." The factory-set overclocks are identical to the numbers designated to Vastarmor's RX 7700 XT Alloy PRO model, although their triple-fan design is slightly slimmer. The longer design accommodates a 90 mm fan, positioned between two 100 mm units.

XFX is reported to be updating its existing Speedster QICK 319 RX 7800 XT Core Edition model—VideoCardz has discovered a pale variant, imaginatively dubbed as the "White Edition." The article does not disclose their source of information and photos, but a quick Google search reveals that Bermor Techzone (BTZ), a Philippines-based e-tailer, has the white version in stock—their listing indicates a price of ₱30,900 (~$552), with no added premium over the existing black model. VideoCardz believes that this is XFX's first foray into white RDNA 3 territories, perhaps in reaction to rival graphics card manufacturers offering a growing pool of almost colorless options.

A SNOW WOLF variant of the Radeon RX 6750 GRE 10 GB card was added to XFX's Chinese product lineup last October, marking the release of their first ever white design deployed on an AMD GPU. We hope to see alternative color options rolled out further up in XFX Radeon RX 7000-series hierarchy, but the QICK 319's treatment does not extend to its PCB (judging from the leaked photos)—fellow Team Red Navi hardware-specialist PowerColor has this market segment cornered it seems. VideoCardz reckons that an official unveiling of XFX's Radeon RX 7800 XT Speedster QICK 319 "white subvariant" is "imminent."

Memory PC GmbH has unveiled an exclusive reskin of Sapphire Technology's standard PULSE RX 7800 XT graphics card—the German e-tailer is advertising this special edition model as a "world first," with a design that is both "unique and eye-catching." We reckon that there is some marketing spiel + exaggeration in effect here, although Memory PC's branding, messaging and extra swathes of red and white do add up to be a more visually appealing package. Sapphire's PULSE card designs tend to focus on function rather than fancy livery—the normal PULSE RX 7800 XT card is almost entirely black, save for some red line accents on its shroud and backplate, plus white text on the twin cooling fans.

This special model sports white PULSE fans with abbreviated Memory PC logo branding, while the shroud has red and white stealth-effect polygonal patterning. This effect adorns almost the entire stretch of backplate, a pixellated heart graphic and a "WE LOVE GAMING" statement sit within an island of black. The Memory PC + Sapphire Technology Navi 32 XT GPU collaboration is only available in pre-built PC systems—starting at €999, with an AMD Ryzen 7 5700X build.

AMD's small Radeon RX 7000M and RX 7000S lines of mobile GPUs based on the latest RDNA 3 graphics architecture includes just five SKUs, spanning the "Navi 31" and "Navi 33" chips. The RX 7000M series only has enthusiast-segment RX 7900M series based on the "Navi 31," and the RX 7600M series based on the "Navi 33," leaving a vast gap that the company plans to fill with RX 7800M series and RX 7700M series SKUs based on the "Navi 32," referred to internally as "Cuarzo Verde." The GPU is meant to be hardwired onto the mainboards of gaming notebooks, however, AMD hands out reference-design MXM boards to OEMs. These were sniffed out in a public shipping manifest harukaze5719 on Twitter.

The "Navi 32" package is roughly similar in size to the compacted "Navi 31" package powering the RX 7900M series. It has a physically smaller 5 nm GCD with 60 compute units compared to the 96 on the "Navi 31" GCD; and is surrounded by four 6 nm MCDs, which give it 64 MB of Infinity Cache, and a 256-bit GDDR6 memory bus. With this, AMD has the option of not just carving out RX 7800M series and RX 7700M series SKUs, but also RX 7900S series SKUs within its segment aimed at gaming-grade ultraportables. We could see some product announcements to this effect Q1 2024, alongside some new desktop SKUs.

Even as NVIDIA inches close to the launch of its RTX 40-series SUPER graphics cards in January, AMD could be preparing a product stack update of its own. While NVIDIA's refresh focuses on the higher end of its lineup, AMD looks to spread out more into the mainstream-performance segments. A regulatory filing with the Eurasian Economic Commission mentions the terms "RX 7600 XT," "RX 7700," and "RX 7800," which fill gaps between the RX 7600, RX 7700 XT, and RX 7800 XT.

There exists a rather big gap between the $230 Radeon RX 7600 and the $450 RX 7700 XT, which AMD is looking to fill with the RX 7600 XT and RX 7700 (non-XT). How AMD goes about carving out these two will be interesting to see. The RX 7600 already maxes out the 6 nm "Navi 33" silicon that it's based on, which means to create the RX 7600 XT, AMD might have to tap into the larger (and much more expensive) "Navi 32" MCM. There is a vast gap between the 32 CU (compute units) available to the RX 7600, and the 54 CU that the RX 7700 XT has (while the silicon itself has 60). Besides CU count, AMD has other levers, such as the MCD (memory cache die) count, which could be down to just 2 for the RX 7600 XT, or 3 for the RX 7700. The Radeon RX 7800 is a different beast. AMD faced quite some flack for positioning the RX 7700 XT within $50 of the RX 7800 XT, and now the former can be had for a street price of roughly $430. To be able to squeeze the RX 7800 between the two, AMD might need to widen the gap by pushing the RX 7700 XT down.

Vastarmor has updated their Alloy graphics card cooling solution with the introduction of customized Radeon RX 7800 XT and RX 7700 XT models—the Chinese manufacturer is keeping things local, so their latest products are unlikely to reach retailers outside of the PRC. This small sticking point has not deterred TPU's GPU database curator—entries have been created for both cards. 4499 RMB (~$612) bags you Vastarmor's Radeon RX 7800 XT Alloy, while their Radeon RX 7700 XT Alloy starts at 3999 RMB (~$545). The two Navi 32 chiplet-based cards appear to share the exact same shroud design and triple-fan setup.

Vastarmor's robust cooling system relies on a 100 + 90 + 100 mm fan array with a somewhat unique visual twist—RGB enthusiasts will be stoked to know that lighting has been integrated into each individual fan. VideoCardz digs the resultant effects: "as the fans spin, gamers will be treated to the mesmerizing sight of what can be described as RGB rings, hopefully nothing too hypnotic." The new Alloy cards arrive with factory set overclocks—providing a rough 5 to 6% climb over AMD's reference figures. Vastarmor has their Radeon RX 7800 XT model configured with 1624/2254/2565 MHz (base/game/boost). The Radeon RX 7700 XT Alloy's spec sheet states 1784/2276/2600 MHz.

GIGABYTE, the world's leading computer brand, announced the GIGABYTE Radeon RX 7800 XT and RX 7700 XT GAMING OC graphics cards hit the market today. Based on AMD's Navi 32 chip using the RDNA 3 architecture, the RX 7800 XT GAMING OC excels in demanding 1440p gaming backed by substantial VRAM and computing power. Meanwhile, the RX 7700 XT GAMING OC emerges as an attractive mid-range option, also promising exceptional performance at 1440p.

Both RX 7800 XT and RX 7700 XT GAMING OC models are equipped with GIGABYTE's acclaimed WINDFORCE cooling system, engineered to ensure peak performance even during extended gaming sessions. This innovative cooling solution features a triple-fan design with Alternating Spinning technology, composite copper heat pipes, Screen Cooling, and an array of exclusive features. These components work in tandem to facilitate efficient heat dissipation, enabling the cards to maintain optimal operating temperatures while keeping noise levels at a minimum.

Argentina's HD Tecnología site has obtained and published AMD's official data outlining the performance prowess of the soon-to-be released Radeon RX 7800 XT & RX 7700 XT GPUs, when stacked up against their closest rivals—NVIDIA GeForce RTX 4060 Ti 16 GB and RTX 4070 12 GB. Team Red could have "cherry-picked" some of this information, and presented resultant performance charts during the grand unveiling of their mid-range RDNA 3 cards at last month's Gamescom press event. HD Tecnología claims that the fuzzy batch of screengrabs were obtained from an official review guide, they chose to not share pages containing precise details of system specifications. An embargo imposed on media outlets is set to be lifted tomorrow, which coincides with the launch of AMD's Navi 32-based contenders.

The test system was running games within a DirectX 12 environment, possibly at maximum settings—general hardware specs included an non-specific AMD Ryzen 7000-series CPU coupled with DDR5 memory on unidentified AM5 motherboard. VideoCardz's abbreviated analysis of the numbers stated: "In summary, without ray tracing, the Radeon RX 7800 XT outperforms the GeForce RTX 4070 by almost 7% on average, while with ray tracing enabled, it maintains a slight 0.5% lead. Conversely, the RX 7700 XT exhibits 16% higher performance over the RTX 4060 Ti 16 GB. However, the presence of ray tracing can tip the scales slightly in NVIDIA's favor, resulting in an 8.5% lead over the AMD GPU."

Scott Herkelman, senior vice president and general manager of AMD's Graphics Business Unit made a slightly unexpected announcement during an IGN live streamed discussion at Gamescom 2023. Following the official unveiling of Radeon RX 7800 XT and RX 7700 XT GPUs on Friday, Herkelman sat down for a brief interview regarding the future of Team Red's RDNA 3 generation—he was asked whether there were any additional Radeon RX 7000-series models on the horizon. In response he stated: "Well, the RDNA3 portfolio is now complete. Of all products that we have planned to launch, that is, this is the last few products that we will launch. We may have some different versions, but they are not a new ASIC…It's been a journey, it's been about a year since we launched the very first RDNA 3 and now we are a year later finishing up the series. We should be done, we are done and we are excited. And now I think we have a broad spectrum covered for people who want RDNA 3 up and down the price tag."

His announcement seemingly confirms that Team Red is satisfied enough to conclude RDNA 3 post the September 6 launch of their Navi 32-based Radeon RX 7800 XT and RX 7700 XT cards, with a grand total of a mere six desktop-oriented SKUs—Herkelman perhaps forgot to mention possible mobile variants. This is slightly odd given that non-XT Radeon RX 7800 and 7700 GPUs have cropped up via leaks in the recent past, and speculation has also pointed to a true entry-level RX 7500 model being in the works. Herkelman hinted that refreshed variants could be released down the road, perhaps akin to the mid-gen update of existing RDNA 2 ASICs (e.g RX 6700 XT -> RX 6750 XT). AMD may rely on its previous generation Radeon technology to fill in the gaps not occupied by RDNA 3—it is believed that an RX 6750 GRE graphics card (RX 6700 non-XT variant) is in the pipeline.

Yeston is reported to be returning to an older Sakura cooler design for its forthcoming AMD Radeon RX 7800 XT and 7700 XT custom graphic cards, as well as a new GeForce RTX 4070 model. The Chinese brand continues to distinguish itself from other graphics card manufacturers with bold aesthetics and bright pastel colors, which also extends to its choice of printed circuit boards. The yet-to-be-released Sakura RX 7800 XT & RX 7700 XT models are set to be the first Navi 32 silicon-based cards to sport white PCBs and I/O brackets. The Yeston design team has made adjustments to the original cooling solution's dimensions—the updated Sakura shroud is now longer (by 3.4 cm) and a bit chunkier (refer to their diagram below) with larger cooling fans attached—VideoCardz posits that the "diameter increased from 83 mm to 91 mm."

Yeston has not published full details about specs, pricing or regional availability for their latest RDNA 3 cards—it has been quite difficult to procure their very unique looking cards outside of the company's home base of China, although Newegg has reportedly managed to sell price-inflated stock of older models in North America. We expect to see more information disclosed by Yeston closer to AMD's officially mandated launch date of September 6 for the much needed mid-range Radeon RX 7000-series entries.

AMD today at Gamescom unveiled the Radeon RX 7800 XT and Radeon RX 7700 XT performance-segment graphics cards. Designed for maxed out gaming at 1440p with ray tracing, the two are designed to square off against NVIDIA's GeForce RTX 4070 series, offering competitive performance and pricing. The two are based on AMD's latest RDNA3 graphics architecture, and use the 5 nm foundry process where it matters. Both cards claim to offer not just superior performance to the specific NVIDIA RTX 40-series SKUs they're designed to compete with, but also better future-proofing, with more video memory on offer.

At the heart of the two is the new "Navi 32" GPU, AMD's second largest chip from this generation. It is a chiplet GPU, just like the "Navi 31" that powers the RX 7900 series, albeit slightly scaled down. The graphics compute die (GCD), the die with the main graphics rendering and compute machinery, is built on the 5 nm EUV foundry node. It is flanked by four memory cache dies (MCDs), each built on the 6 nm foundry node. These are the same MCDs found in the "Navi 31," but four in number instead of six, which gives the "Navi 32" a 256-bit wide GDDR6 memory interface.

AMD, in a now-deleted tweet, revealed what it is probably going to announce later today—the Radeon RX 7800 XT and RX 7700 XT desktop graphics cards. The company briefly tweeted the marketing flier for these cards, before deleting it, but not before VideoCardz saved a copy. This flier confirms the SKU names RX 7800 XT and RX 7700 XT up for launch; and gives us two images of the Made by AMD (reference design) graphics card. It appears like AMD is using a common board design for both SKUs.

The reference Radeon RX 7800 XT appears to be a slightly shrunk down version of the RX 7900 XT reference. The dual-slot card comes with two axial-flow fans instead of three on the RX 7900 XT. The card draws power from two 8-pin PCIe power connectors. Earlier this month, a leak by PowerColor spilled the beans on the RX 7800 XT being based on the "Navi 32" silicon. A chiplet-based GPU just like the "Navi 31" powering the RX 7900 series; the Navi 32 is maxed out by the RX 7800 XT, and packs 3,840 stream processors, 120 AI accelerators, 60 Ray accelerators, 64 MB of Infinity Cache memory, and a 256-bit GDDR6 memory interface, which holds 16 GB of memory on the RX 7800 XT. Specs of the RX 7700 XT remain under the wraps.

AMD Radeon RX 7700 XT is confirmed to feature 12 GB as its standard memory size, and feature a 192-bit wide GDDR6 memory interface, according to a leaked regulatory filing by ASRock for its upcoming graphics cards. We already know from last week's mega leak of the PowerColor RX 7800 XT Red Devil that the card maxes out the "Navi 32" silicon, enabling all 60 RDNA3 CU, and comes with 16 GB of memory across the chip's full 256-bit memory bus. This filing suggests how AMD will carve the RX 7700 XT out.

Probably designed to compete with the GeForce RTX 4070, the RX 7700 XT is based on the same "Navi 32" silicon as the RX 7800 XT, but cut down. AMD is expected to disable some of the 60 CU physically present on the 5 nm GCD, while one of the four 6 nm MCDs will be disabled, giving the chip a 192-bit memory bus to drive its 12 GB of memory. We know from the PowerColor leak that the RX 7800 XT gets 18 Gbps memory speed. It remains to be seen if AMD sticks with this speed for even the RX 7700 XT, in which case, it gets 432 GB/s of memory bandwidth at its disposal. AMD is expected to launch the RX 7800 XT and RX 7700 XT within this quarter (before October).

PowerColor inadvertently released the first pictures of its AMD Radeon RX 7800 XT Red Devil graphics card. These pictures confirm that the RX 7800 XT is based on a maxed out version of the "Navi 32" GPU, and not the compact "Navi 31" powering the limited edition RX 7900 GRE. The "Navi 32" is a chiplet-based GPU, just like the "Navi 31," albeit smaller. Its 5 nm GCD (graphics compute die) physically features 60 RDNA3 compute units, which work out to 3,840 stream processors, 120 AI accelerators, 60 Ray accelerators, 192 TMUs, and possibly 128 ROPs. This GCD is surrounded by four 6 nm MCDs (memory cache dies), which each has a 16 MB segment of the GPU's 64 MB Infinity Cache memory, and make up its 256-bit GDDR6 memory interface.

The specs sheet put out by PowerColor confirms that the RX 7800 XT maxes out the "Navi 32," enabling all 60 CUs, and the chip's full 256-bit memory interface, to drive 16 GB of memory. The RX 7800 XT uses 18 Gbps memory speed, and hence has 576 GB/s of memory bandwidth at its disposal. The PowerColor RX 7800 XT Red Devil has dual-BIOS, and assuming the "standard/silent" BIOS runs the card at AMD reference clock speeds, we're looking at Game clocks of 2210 MHz, and 2565 MHz boost. The Red Devil draws power from a dual 8-pin PCIe power connector set up (375 W max); the cooler is visibly smaller than the one on the company's RX 7900 series Red Devil cards. A 16+2 phase VRM powers the card. With pictures of the card out, we expect a global product launch within the next 30 days.

AMD's Chinese office has announced that company representatives will be present at this year's ChinaJoy event—their Weibo social media account confirmed that: "from July 28th to July 31st, 2023, in Hall E6 of Shanghai New International Expo Center, super hardcore and mega cool AMD hardware will be on the scene, bringing you a fast and fun gaming experience. We are looking forward to meeting you!" ITHome thinks that the timing of this announcement points to a possible official unveiling of the Radeon RX 7900 GRE (Golden Rabbit Edition) on the showroom floor.

The publication has cited a tip provided by the one and only momomo_us—the Chinese market exclusive Golden Rabbit Edition will be released tomorrow, which lines up with ChinaJoy 2023's kick off time. Recent leaks have revealed that the 84 Compute Units + 16 GB configured graphics card is a new SKU, sitting below the RX 7900 XT in Team Red's Radeon RDNA 3 hierarchy. It seems to be "built on the mysterious Navi 31 + Navi 32 hybrid GPU." Additionally, ITHome reports that AMD has partnered up with ASUS, and will be exhibiting ROG Moba 7 Plus series laptops (sporting Ryzen Dragon Range APUs) at the Shanghai event.

A set of intriguing 3DMark Time Spy benchmark results have been released by hardware leaker All_The_Watts!!—these are alleged to have been produced by prototype Radeon RX 7700 and Radeon RX 7800 graphics cards (rumored to be based on variants of the Navi 32 GPU). The current RDNA 3 lineup of mainstream GPUs is severely lacking in middle ground representation, but Team Red is reported to be working on a number of models to fill in the gap. We expect a number of leaks to emerge as we get closer to a rumored product reveal scheduled for late August (to coincide with Gamescon).

The recently released 3DMark Time Spy scores reveal that the alleged Radeon RX 7700 candidate scored 15,465 points, while the RX 7800 achieved 18,197 points—both running on an unspecified test system. The results (refer to the Tom's Hardware-produced chart placed below) are not going to generate a lot of excitement at this stage when compared to predecessors and some of the competition—evaluation samples are not really expected to be optimized to a great degree. We hope to see finalized products with decent drivers putting in a good appearance and performing better later on this year.

AMD is planning to plug the Atlantic gap between its mainstream Radeon RX 7600 and enthusiast-class RX 7900 XT with the RX 7800 series and RX 7700 series, with either an announcement or teaser planned for 2023 Gamescom, which is scheduled for August. There could be up to four new graphics card SKUs announced, with their product launches spread across Q3 and Q4 2023. The "Navi 32" MCM is expected to power at least three of these SKUs, while it was recently rumored that AMD could design a new GPU that has the GCD of the "Navi 31" on the package of "Navi 32" with its four MCDs, to end up with a higher CU count than what the "Navi 32" can offer.

The "Navi 32" GPU is an MCM, just like the "Navi 31" powering the RX 7900 series. It is rumored to feature a 5 nm GCD (graphics compute die) with 60 RDNA3 compute units, which work out to 3,840 stream processors, 120 AI accelerators, 60 Ray Accelerators, 240 TMUs, and possibly 128 ROPs. The four 6 nm MCDs give it 64 MB of Infinity Cache, and a 256-bit wide GDDR6 memory interface. Assuming the RX 7800 XT uses the unnamed new MCM with the GCD of the "Navi 31" that has a CU count somewhere between 60 and 72, a maxed-out "Navi 32" could power the RX 7800, while its cut-down variants power the RX 7700 XT and RX 7700.

AMD Radeon RX 7800 XT will be a much-needed performance-segment addition to the company's Radeon RX 7000-series, which has a massive performance gap between the enthusiast-class RX 7900 series, and the mainstream RX 7600. A report by "Moore's Law is Dead" makes a sensational claim that it is based on a whole new ASIC that's neither the "Navi 31" powering the RX 7900 series, nor the "Navi 32" designed for lower performance tiers, but something in between. This GPU will be AMD's answer to the "AD103." Apparently, the GPU features the same exact 350 mm² graphics compute die (GCD) as the "Navi 31," but on a smaller package resembling that of the "Navi 32." This large GCD is surrounded by four MCDs (memory cache dies), which amount to a 256-bit wide GDDR6 memory interface, and 64 MB of 2nd Gen Infinity Cache memory.

The GCD physically features 96 RDNA3 compute units, but AMD's product managers now have the ability to give the RX 7800 XT a much higher CU count than that of the "Navi 32," while being lower than that of the RX 7900 XT (which is configured with 84). It's rumored that the smaller "Navi 32" GCD tops out at 60 CU (3,840 stream processors), so the new ASIC will enable the RX 7800 XT to have a CU count anywhere between 60 to 84. The resulting RX 7800 XT could have an ASIC with a lower manufacturing cost than that of a theoretical Navi 31 with two disabled MCDs (>60 mm² of wasted 6 nm dies), and even if it ends up performing within 10% of the RX 7900 XT (and matching the GeForce RTX 4070 Ti in the process), it would do so with better pricing headroom. The same ASIC could even power mobile RX 7900 series, where the smaller package and narrower memory bus will conserve precious PCB footprint.

An AMD Navi 32 die was belatedly observed in a Forbes video feature on the company's CEO and President Lisa Su—this small tidbit fired up the PC hardware community once again with speculation about why Team Red has not yet released proper mid-range RDNA 3 game-oriented models. A handful of news sites have recently reported that a Navi 32 GPU sits at the heart of AMD's fairly new workstation-grade AMD Radeon Pro W7800 32 GB GDDR6 graphics card, but fact checkers have quickly pointed out that the $2499 (MSRP) product is actually based on Navi 31. Sites have theorized about the makeup of a possible "Radeon RX 7800" GPU and assumed that a similarly named/numbered workstation model would offer a preview of things to come.

Igor Wallossek (of Igor's Lab fame) has conducted an interesting investigation into this matter. He has put a Radeon Pro W7800 test unit through its paces as a gaming card, but the high-end nature of the Navi 31 GPU leads him to believe that the performance level on tap would be roughly equivalent to a hypothetical "RX 7800 XT." Igor assumes that his simulated gaming card will have access to a smaller pool of VRAM (16 GB instead of 32 GB)—he achieves this via the memtestcl program, since "RDNA 3 no longer allows us to emulate the cards directly." He also sets provisions for differing power consumption due to the workstation card being an efficiency-focused product: "The Radeon Pro W7800 has a TBP of 260 watts, my own extrapolation results in a TBP of around 270 watts for the RTX 7800XT based on the efficiency values of the other two Navi 31 cards."

Forbes published its video interview with AMD CEO and President Lisa Su at the end of May, but it has taken two weeks for hardware news sites to realize that unreleased silicon was in plain view within the spotlight piece. Folks likely regarded it as a simple puff piece due to the title reading "This CEO Made AMD Billions - Now She Wants To Dominate The Market With AI." Hoang Anh Phu, a Vietnamese technology enthusiast, managed to pay close attention to a curious segment in the Forbes video and uploaded AI-upscaled screengrabs to Twitter along with the comment/question: "Navi 32 die shot(?!)."

RDNA3 Navi 31 and Navi 33 GPU products have already reached the retail market—AMD's high-end (chiplet design) Radeon RX 7900-series is based on the former and it launched last December. The latter arrived in the (monolithic N33 XL) form of Radeon RX 7600 cards at the end of May 2023. Even board partners are seemingly becoming impatient about a lack of new offerings in the mid-range—Sapphire is very likely to release another previous gen Radeon RX 6750 XT custom card this week in China. Team Red has not publicly acknowledged that Navi 32 is a work in-progress, so it is slightly odd that an example sat next to EPYC Genoa, Raphael, and Raphael X3D dies on a table—as spotted in the Forbes feature. Screenshots show an Infinity Cache setup with four memory stacks on a previously unseen die. Leaks have indicated that Navi 32 will be a chiplet design with a GCD (200 mm²) in the middle, surrounded by the four MCDs (37.5 mm²). The full package area size is eyeball estimated to occupy around 350 mm² of space, which corroborates info uncovered in the past.

A bunch of unreleased AMD Radeon RX 7000 series graphics card have been spotted in ROCm 5.6 pull request, including the Radeon RX 7950 XTX, 7950 XT, 7800 XT, 7700 XT, 7600 XT, and 7500 XT. AMD has not yet launched its mainstream Radeon RX 7000 graphics cards, but according to the latest pull request, there are several unreleased graphics cards in for both high-end and mainstream segments. While the pull request has been removed from GitHub, it has been saved on Reddit. So far, it appears that AMD's RDNA 3 Radeon 7000 series lineup will be based on just three GPUs, Navi 33, Navi 32, and the Navi 31.

According to the list, we can expect a high-end refresh with Radeon RX 7950 XTX/XT version, also based on Navi 31 GPU. The list also shows that the Radeon RX 7800 series will be the only one based on the Navi 32 GPU, at least for now, while the Navi 33 GPU should cover the entire mainstream lineup, including the Radeon RX 7700 series, Radeon RX 7600 series, and the Radeon RX 7500 series. The list only includes XT versions, while non-XT should show up later, as it was the case with the Radeon RX 6000 series graphics cards. AMD's President and CEO, Dr. Lisa Su, already confirmed during Q1 2023 earnings call that mainstream Radeon RX 7000 series GPUs based on RDNA 3 architecture will launch during this quarter, and earlier rumors suggest we might see them at Computex 2023.

The unified shader (stream processor) counts of AMD's upcoming second- and third-largest GPUs based on the RDNA3 graphics architecture, have been leaked in some ROCm code, discovered by Kepler_L2 on Twitter. The "performance.hpp" file references "Navi 32" with a compute unit count of 60, and the "Navi 33" with 32 compute units. We know from the "Navi 31" specifications that an RDNA3 compute unit still amounts to 64 stream processors (although with significant IPC uplifts over the RDNA2 stream processor due to dual-instruction issue-rate).

60 compute units would give the "Navi 32" silicon a stream processor count of 3,840, a 50% numerical increase over the 2,560 of its predecessor, the "Navi 22," powering graphics cards such as the Radeon RX 6750 XT. Meanwhile, the 32 CU count of the "Navi 33" amounts to 2,048 stream processors, which is numerically unchanged from that of the "Navi 23" powering the RX 6650 XT. The new RDNA3 compute unit has significant changes over RDNA2, besides the dual-issue stream processors—it gets second-generation Ray Accelerators, and two AI accelerators for matrix-multiplication.
