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.

AMD's future RDNA 5 graphics architecture will bear a "clean sheet" design, and may probably not even have the RDNA branding, says WJM47196, a source of AMD leaks on ChipHell. Two generations ahead of the current RDNA 3 architecture powering the Radeon RX 7000 series discrete GPUs, RDNA 5 could see AMD reimagine the GPU and its key components, much in the same way RDNA did over the former "Vega" architecture, bringing in a significant performance/watt jump, which AMD could build upon with its successful RDNA 2 powered Radeon RX 6000 series.

Performance per Watt is the biggest metric on which a generation of GPUs can be assessed, and analysts believe that RDNA 3 missed the mark with generational gains in performance/watt despite the switch to the advanced 5 nm EUV process from the 7 nm DUV. AMD's decision to disaggregate the GPU, with some of its components being built on the older 6 nm node may have also impacted the performance/watt curve. The leaker also makes a sensational claim that "Navi 31" was originally supposed to feature 192 MB of Infinity Cache, which would have meant 32 MB segments of it per memory cache die (MCD). The company instead went with 16 MB per MCD, or just 96 MB per GPU, which only get reduced as AMD segmented the RX 7900 XT and RX 7900 GRE by disabling one or two MCDs.

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.

"Navi 4C" is a future high-end GPU from AMD that will likely not see the light of day, as the company is pivoting away from the high-end GPU segment with its next RDNA4 generation. For AMD to continue investing in the development of this GPU, the gaming graphics card segment should have posted better sales, especially in the high-end, which it didn't. Moore's Law is Dead scored details of what could have been a fascinating technological endeavor for AMD, in building a highly disaggregated GPU.

AMD's current "Navi 31" GPU sees a disaggregation of the main logic components of the GPU that benefit from the latest 5 nm foundry node to be located in a central Graphics Compute Die; surrounded by up to six little chiplets built on the older 6 nm foundry node, which contain segments of the GPU's Infinity Cache memory, and its memory interface—hence the name memory cache die. With "Navi 4C," AMD had intended to further disaggregate the GPU, identifying even more components on the GCD that can be spun out into chiplets; as well as breaking up the shader engines themselves into smaller self-contained chiplets (smaller dies == greater yields and lower foundry costs).

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.

The GPU at the heart of the China-exclusive AMD Radeon RX 7900 GRE (Golden Rabbit Edition) sparked much curiosity. It is a physically different GPU from the one found in desktop Radeon RX 7900 XT and RX 7900 XTX graphics cards. AMD wouldn't go through all that effort designing a whole different GPU just for a limited edition graphics card, which means this silicon could find greater use for the company—for example, this could be the package AMD uses for its upcoming mobile RX 7900 series. AMD wouldn't go through all the effort designing a first-party MBA (made by AMD) PCB for the silicon just for the RX 7900 GRE, and so this PCB, with this particular version of the "Navi 31" silicon, could see a wider global launch, probably as the rumored Radeon RX 7800 XT, or something else (although with a different set of specs from the RX 7900 GRE).

We compared the sizes of the new "Navi 31" package found in the RX 7900 GRE, with those of the regular "Navi 31" powering the RX 7900 XT/XTX, the previous-generation "Navi 21" powering the RX 6900 XT, and the NVIDIA AD103 silicon powering the desktop GeForce RTX 4080. There are some interesting findings. The new smaller "Navi 31" package is visibly smaller than the one powering the RX 7900 XT/XTX. It is a square package, compared to the larger rectangular one, and has a significantly thinner metal reinforcement brace. What's interesting is that the 5 nm GCD is still surrounded by six 6 nm MCDs. We don't know if they've disabled two of the six MCDs, or whether they're dummies. AMD uses dummy chiplets as structural reinforcement in some of its EPYC server processors. The dummies spread some of the mounting pressure applied by the IHS or cooling solution, so the logic behind surrounding the GCD with six of these MCDs could be the same.

Here are some of the first pictures of the Sapphire Radeon RX 7900 GRE, a unique China-specific product that isn't just its own Sapphire custom-design, but also a whole different SKU. We first learned about the existence of the RX 7900 GRE earlier this month, and this would be one of its first custom design implementations. The Golden Rabbit Edition (GRE), is a limited edition SKU of the Radeon RX 7900 series. It's neither the RX 7900 XTX nor the RX 7900 XT, but positioned a notch below the latter. Based on the same "Navi 31" silicon as the two, the RX 7900 GRE is equipped with 84 CU (5,376 stream processors), or the same GCD core-configuration as the RX 7900 XT. It however, gets just 16 GB of memory, across a narrower 256-bit wide memory bus.

The Radeon RX 7900 GRE is carved out of the "Navi 31" by disabling two of the six MCDs, which reduces the Infinity Cache size to 64 MB, and the GDDR6 memory bus width to 256-bit. The 5 nm GCD is carried over from the RX 7900 XT—you get 5,376 stream processors, 168 AI accelerators, 84 Ray accelerators, 336 TMUs, and 192 ROPs. It is possible that the Sapphire RX 7900 GRE uses a variation of the company's NITRO+ cooling solution that's similar to the NITRO+ Lite SKUs available in markets outside China. The key difference here is that the cooler lacks a vapor-chamber plate, and instead uses a solid copper base-plate to pull heat from the GPU and memory. AMD needs to fill the vast gap in its product stack between the $250 RX 7600 and the $700+ RX 7900 XT, and SKUs such as the RX 7900 GRE could help it compete better against the likes of the RTX 4070 Ti in competitive markets such as China.

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.
