Alphacool Unveils New Eisblock Full-coverage Blocks for Radeon RX 7900 Series

The new AMD Radeon RX 7900 XT (X) GPU is here! And Alphacool offers its new Eisblock Aurora cooler, a new, innovative active water cooler for custom layouts of AMD Radeon graphics cards. With significant improvements over the previous Aurora generation, Alphacool now takes it a big step further. What's new. Going forward, Alphacool is now using chrome plating on the copper radiators for all graphics card coolers instead of nickel plating. This is significantly harder and more resistant than nickel plating. The addressable RGB LED lighting also shines better because the chrome plating is much smoother and distributes the light even more beautifully in the cooler.

To dissipate the enormous amount of waste heat, the water flow has been completely redesigned. The jetplate is embedded in the cooling fins and is pressed onto them by a completely redesigned inlet with an O-ring. This ensures that the water is reliably forced through the cooling fins. Optimization of the cooling fins leads to a further increase in performance. The cooling fins were reduced to 0.4 mm and the distance between the fins was minimized to 0.4 mm. This creates a larger cooling surface and reduces the flow resistance of the cooler. This results in a performance plus.

First Alleged AMD Radeon RX 7900-series Benchmarks Leaked

With only a couple of days to go until the AMD RX 7900-series benchmarks go live, some alleged benchmarks from both the RX 7900 XTX and RX 7900 XT have leaked on Twitter. The two cards are being compared to a NVIDIA RTX 4080 card in no less than seven different game titles, all running at 4K resolution. The games are God of War, Cyberpunk 2077, Assassin's Creed Valhalla, Watchdogs Legion, Red Dead Redemption 2, Doom Eternal and Horizon Zero Dawn. The cards were tested on a system with a Core i9-12900K CPU which was paired with 32 GB of RAM of unknown type.

It's too early to draw any real conclusions from this test, but in general, the RX 7900 XTX comes out on top, ahead of the RTX 4080, so no surprises here. The RX 7900 XT is either tied with the RTX 4080 or a fair bit slower, with the exception being Red Dead Redemption 2, where the RTX 4080 is the slowest card, although it also appears to have some issues, since the one percent lows are hitting 2 FPS. Soon, the reviews will be out and everything will become more clear, but it appears that AMD's RX 7900 XTX will give NVIDIA's RTX 4080 a run for its money, if these benchmarks are anything to go by.

Update Dec 11th: The original tweet has been removed, for unknown reasons. It could be because the numbers were fake, or because they were in breach of AMD's NDA.

PowerColor Reveals the Red Devil 7900-series

Three weeks ago, PowerColor teased its Radeon RX 7900-series Red Devil cards on social media, but now the company has revealed more details of its upcoming cards. Oddly enough, PowerColor hasn't gone for RGB fans here, unlike its Hellhound cards, although the Red Devil cards do have a lot of RGB accents. A unique, if somewhat pointless feature is that the Red Devil cards come with a removable backplate cover, so you can choose to have a "plain" metal backplate, or a rather unusual looking backplate that appears to be made mostly out of plastic.

As with the Hellhound cards, PowerColour has used a 14-layer PCB for the Red Devil cards, but has added a 21st VRM for some reason, as the Hellhound cards "only" have 20 VRMs. The heatsinks with eight heatpipes appear to be nigh on identical to the one used on the Hellhound cards. PowerColour has also installed a side-mounted metal bracket to help prevent GPU sag, but it appears as if the bracket only reaches half way down the length of the card. The Red Devil cards have three 8-pin power connectors. What is unclear is what type of display interfaces the cards will have, as PowerColor didn't provide an image of that side of the cards, but based on the PCB picture, USB-C doesn't appear to be part of the mix.

GIGABYTE Launches AMD Radeon RX 7900 Series Graphics Cards

GIGABYTE TECHNOLOGY Co. Ltd, a leading manufacturer of premium gaming hardware, today announced the new AMD Radeon RX 7900 Series graphics cards powered by the high-performance, energy-efficient AMD RDNA 3 architecture - the AORUS Radeon RX 7900 XTX ELITE 24G, Radeon RX 7900 XTX GAMING OC 24G, Radeon RX 7900 XTX 24G, Radeon RX 7900 XT GAMING OC 20G and Radeon RX 7900 XT 20G graphics cards. The new graphics cards will be available for purchase on December 13, 2022.

The new graphics cards are the world's first gaming graphics cards to feature an advanced AMD chiplet design, delivering exceptional performance and superb energy efficiency to power high-framerate 4K and higher resolution gaming in the most demanding titles.

Gigabyte's and Sapphire's Radeon RX 7900-series Cards Pictured

Courtesy of VideoCardz, we now know what Gigabyte's and Sapphire's upcoming Radeon RX 7900-series cards will look like. Gigabyte will offer at least two different custom designed models, with the Aorus Elite being the higher-end one and the Gaming OC being the mainstream one. Both appear to come in RX 7900 XTX and RX 7900 XT SKUs. The Aorus Elite is said to be a 3.5-slot card sporting three 8-pin power connectors, whereas the Gaming OC is a 2.5-slot card with two 8-pin power connectors.

The Sapphire card in question is the Nitro+ which has been given a design overhaul compared to the Radeon RX 6000-series cards and it's quite a bright card thanks to its silver coloured shroud. We're once again looking at a massive cooler here, which is wider than three slots, but maybe not quite 3.5-slots wide. Unsurprisingly, Sapphire has kitted out the card with three 8-pin power connectors. None of the three cards have a USB-C port and it appears that those looking to get an AMD Radeon RX 7900-series card with a USB-C port, would have to go for the reference design cards.

ASRock Launches AMD Radeon RX 7900 Series Graphics Cards Unlock Your Gaming Power and Creativity

ASRock, the leading global motherboard, graphics card and mini PC manufacturer, today launched the new AQUA, Taichi and Phantom Gaming series graphics cards based on AMD Radeon RX 7900 Series GPUs.

The new graphics cards are built on the groundbreaking AMD RDNA 3 architecture with chiplet technology. AMD RDNA 3 architecture delivers up to 54% more performance per watt than AMD RDNA 2, features the world's fastest interconnect linking the graphics and memory system chiplets at up to 5.3 TB/s, and offers up to 96 new unified compute units and second-generation AMD Infinity Cache technology. It also delivers increased AI throughput that provides up to 2.7X higher AI performance, and rearchitected compute units with second-generation ray tracing technology that provides up to 1.8X higher ray tracing architectural performance in select titles versus AMD RDNA 2 architecture.

ASRock and XFX Radeon RX 7900-series Custom Design Cards Leak

As we're getting closer to the official launch date, pictures of AMD Radeon RX 7900-series cards from both ASRock and XFX have tipped up online. The ASRock cards are part of its Phantom Gaming and Taichi series of cards, whereas the XFX card is part of the MERC line. Sadly none of the cards appear to sport a USB-C port, suggesting that it's not a feature that any of the OEM's have thought worthwhile to include in their custom board designs.

The ASRock Phantom Gaming cards appear to be 2.5-slot cards, whereas the Taichi cards are triple slot. The Phantom Gaming cards seem to be equipped with a short backplate that only covers the rear of the PCB, rather than the full length of the card, with the Taichi cards seemingly having a full-length backplate. The XFX MERC 310 also appears to be a 2.5-slot design, but it has a very different backplate design which appears to act much more as a heatsink than most backplate designs we've seen to date. The fact that it appears to be made of a large chunk of aluminium that wraps around the back edge of the card is also rather unusual. XFX also appears to have gone with the same size for its RX 7900 XT and RX 7900 XTX cards. We can also see that XFX has gone for three 8-pin power connectors for their cards.

NVIDIA GeForce RTX 4080 Could Get a Price Cut to Better Compete with RDNA3

NVIDIA GeForce RTX 4080 graphics card has been out since mid-November and is a great performer in many resolutions and titles. However, with NVIDIA setting its price tag at $1200, it is an expensive product to afford and represents a considerable price jump compared to older xx80 GPU generations. According to MyDrivers, NVIDIA could lower the price starting in mid-December, to better suit the needs of consumers and have a competitive product. With AMD's RDNA3-based graphics cards releasing in the following days, the Radeon RX 7900 XTX costing $999 is a direct competitor to GeForce RTX 4080. If NVIDIA plans to cut the massive MSRP of the RTX 4080, then we expect it to be in the range of Radeon RX 7900 XTX to create better market competition.

Of course, this is only wishful thinking and a rumor that MyDrivers has reported, so we have to wait until the middle of this month to find out if NVIDIA announces the alleged price cut.

Sapphire's Radeon RX 7900 Cards Make an Early Appearance on Amazon

Although we're almost two weeks away from the official launch of AMD's Radeon RX 7900-series, Sapphire's reference design cards have already made an early appearance on Amazon. Both of its cards are listed on the e-tailers website, but sadly without pricing. No new specs were provided either, but at least we did get some more detailed pictures of the two cards. The cards are simply named the Radeon RX 7900 XT Gaming (21323-01-20G) and the Radeon RX 7900 XTX Gaming (21322-01-20G).

It's very clear from the pictures that the Radeon RX 7900 XTX is a much chunkier card than the RX 7900 XT. This also confirms Sapphire as one of the partners that will sell reference cards, but it's unclear if Sapphire will have custom cards ready in time for the launch, or if the company will add those to its line-up at a later date. Note that the model number for the Radeon RX 7900 XTX lists it as having 20 GB of VRAM, although the packaging clearly lists it as having 24 GB. Searching for the model numbers provided by Amazon, it appears that the cards will be in stock in Sweden as well, as one of the local distributors is listing the cards. More pictures after the break.

PowerColor Announces its Hellhound 7900-series Graphics Cards

With 11 days to go until the official launch of AMD's Radeon 7900-series graphics cards, PowerColor decided to share some more details about its upcoming cards. The two models appear to be the Hellhound Radeon RX 7900 XTX and the Hellhound Radeon RX 7900 XT, with both cards apparently sharing the same design and cooler. The cards appear to be at least triple-slot, but it's not entirely clear from the provided pictures. PowerColor is using a nine-blade fan design and the fans are of course kitted out with LEDs, where PowerColor is pushing what it calls an "amethyst purple" colour for this generation of Hellhound cards. The new fans are said to improve the GPU temperatures by as much as three degrees Celsius compared to the previous generation of fans.

More importantly, the cards have been given an improved backplate, as well as a larger copper plate for the heatsink, for improved cooling. The new copper plate doesn't just cover the GPU now, but also the VRAM chips. The copper plate is connected to eight 6 mm heatpipes. PowerColor also shared that it's using a 14-layer high TG PCB, which uses a two ounce copper power layer. The RX 7900 XTX is kitted out with 20 VRMs, although this appears to be straight from the AMD reference design. PowerColor appears to have implemented a dual BIOS on the card, as there's a switch for OC/Silent operation and the card also appears to have a hardware LED switch, which is nice for those that don't care about lighting up their computer like a Christmas tree. Keep in mind that this is not PowerColor's top-of-the-range card, which is the Red Devil, so we should expect more details on those cards in the future too.

Sapphire Teases its Radeon RX 7900-series Nitro Card

It appears that we're in the Radeon RX 7900-series teaser season, as yet another upcoming card has been teased on social media, this time by Sapphire. The company didn't share any details about the card, beyond the fact that's its an RX 7900 based card of some kind. The company shared a short video of the fans spinning on the card, from an angle that gives away as few details as possible. Beyond being able to tell that the card has triple-fan cooling solution and a silver coloured shroud, the only thing visible appears to be two RGB LED strips that runs along the length of the card.

Non-reference AMD Radeon RX 7900 Series RDNA3 to Launch by Late-December

AMD Radeon RX 7900 XTX and RX 7900 XT RDNA3 graphics cards debut on December 13, 2022. This is when you will be able to buy one, at an MSRP of $999 for the RX 7900 XTX, and $899 for the RX 7900 XT. These will, however, only be reference-design MBA (made by AMD) graphics cards sold though the company's various add-in board (AIB) partners. The non-reference (custom design) RX 7900 series reportedly releases to the market 1 to 2 weeks after December 13, according to a Board Channels report seen by Wccftech.

Unlike the NVIDIA Founders Edition graphics card that's sold exclusively under the NVIDIA marquee, AMD's reference-design cards are sold by its AIB partners, with minimal or nil partner branding on the cards. The after-sales support, including product warranties and other brand-specific inclusions, are handled by the AIBs themselves. Custom-design cards are those designed by the AIB partners, with customization extending to both the cooling solution and the PCB; and with some cards even featuring factory-overclocked speeds. These are the ones that could launch 1 to 2 weeks after December 13, which would put their launch anywhere between December 20 to 27 (our yikes go out to reviewers).

PowerColor Shows Off the Radeon RX 7900 Red Devil on Social Media

Although we're only some three weeks away from the launch of AMD's Radeon RX 7000-series cards, it has been pretty quiet from its partners. That said, PowerColor has finally revealed more than just a tiny detail of its upcoming Radeon RX 7900 Red Devil via a post on Facebook. The company didn't reveal any specs and it's unclear if this will be an RX 7900 XT or an RX 7900 XTX based card.

What we can see from the picture is that it's a triple-slot card with air being vented out the rear, something AMD's reference cards don't do. It's obviously a triple-fan card and PowerColor has equipped it with some LED lights as one would expect. Not much else is revealed by the single picture of the card, due to the angle the card sits at, so we don't know what kind of ports to expect, or what kind of power connectors the card will have. Hopefully PowerColor will reveal more details before the official launch on the 13th of December.

AMD Confirms Radeon RX 7900 Series Clocks, Direct Competition with RTX 4080

AMD in its technical presentation confirmed the reference clock speeds of the Radeon RX 7900 XTX and RX 7900 XT RDNA3 graphics cards. The company also made its first reference to a GeForce RTX 40-series "Ada" product, the RTX 4080 (16 GB), which is going to launch later today. The RX 7900 XTX maxes out the "Navi 31" silicon, featuring all 96 RDNA3 compute units or 6,144 stream processors; while the RX 7900 XT is configured with 84 compute units, or 5,376 stream processors. The two cards also differ with memory configuration. While the RX 7900 XTX gets 24 GB of 20 Gbps GDDR6 across a 384-bit memory interface (960 GB/s); the RX 7900 XT gets 20 GB of 20 Gbps GDDR6 across 320-bit (800 GB/s).

The RX 7900 XTX comes with a Game Clocks frequency of 2300 MHz, and 2500 MHz boost clocks, whereas the RX 7900 XT comes with 2000 MHz Game Clocks, and 2400 MHz boost clocks. The Game Clocks frequency is more relevant between the two. AMD achieves 20 GB memory on the RX 7900 XT by using ten 16 Gbit GDDR6 memory chips across a 320-bit wide memory bus created by disabling one of the six 64-bit MCDs, which also subtracts 16 MB from the GPU's 96 MB Infinity Cache memory, leaving the RX 7900 XT with 80 MB of it. The slide describing the specs of the two cards compares them to the GeForce RTX 4080, which is what the two could compete more against, especially given their pricing. The RX 7900 XTX is 16% cheaper than the RTX 4080, and the RX 7900 XT is 25% cheaper.

AMD Radeon RX 7900 XTX Reference Design PCB and Cooler Detailed

AMD Radeon RX 7900 XTX reference-design isn't a first-party product with limited availability like the NVIDIA Founders Edition; but rather a classic reference-design that's sold by AMD's add-in board partners under their marquee (without sticking their own labels on the product). AMD and its partners internally refer to reference-design cards as "MBA cards" (made by AMD cards). The company gave us a technical overview of the reference-design PCB. As with every reference AMD PCB for the past several generations, the RX 7900 XTX PCB has a premium selection of components. The card uses an expensive 14-layer PCB with 4 additional layers of 2-oz copper. 14-layer PCBs are typically used with enterprise-grade products, and graphics cards typically tend to have PCB layer counts of around 10. The PCB also uses ITEQ IT-170GRA epoxy and laminate materials, which enable a glass transition temperature (Tg) of 175 °C (no, the GPU won't get anywhere near as hot).

The reference-design RX 7900 XTX PCB draws power from two 8-pin PCIe power connectors. With the typical board power of the RX 7900 XTX rated at 355 W, this falls inside the 375 total power-draw capability when you add up the 150 W input from the two connectors, and 75 W from the PCIe slot. AMD worked to minimize power-draw spikes at least from the PCIe slot. Excursions, if any, should be localized to the 8-pin power connectors. The card features 20-phase VRM solution, using "high efficiency" DrMOS power-stage phases (could be very high current). The "Navi 31" GPU is surrounded by 12 GDDR6 memory chips given the GPU's 384-bit memory interface. Two of these memory pads could end up unused on the RX 7900 XT, which has a 320-bit memory interface. Display outputs of the RX 7900 series include two standard-size DisplayPort 2.1, one USB type-C with DisplayPort passthrough; and one HDMI 2.1a.

AMD Radeon RX 7900 XTX RDNA3 Reference Design Features Fan Intake Temp Sensors, ARGB LEDs

AMD Radeon RX 7900 XTX reference design graphics card features an innovative new real-time monitoring feature, the Fan Intake Temperature Sensors. The reference-design RX 7900 XTX cooler has the ability to report individual fan-speeds to software (which isn't new, given that each fan will independently connect to the PCB); but what's new is that each of the fans has a temperature sensor that can detect the temperature of the air as it's being drawn in, before reaching the heatsink.

The temperature measurement of the fan intake sensors should give you a fair idea of what is the ambient temperature inside your case. At this point we don't know if the feature is exclusive to the AMD reference design, or if the company has shared the know-how with its add-in board (AIB) partners to add to their custom-design products. This sensor should be accessible by AMD Software, the utilities included by AIB partners, and we will try to add ability to read from this sensor to TechPowerUp GPU-Z. The reference RX 7900 XTX cooler also features addressable RGB LEDs, first ever for a reference-design graphics card (they've had single-color lighting).

PowerColor Radeon RX 7900 XTX HellHound Pictured

PowerColor put out its first teaser of a custom-design Radeon RX 7900 XTX graphics card, the RX 7900 XTX HellHound. The teaser is a back 3-quarter picture of the card, revealing its well-ventilated dual aluminium fin-stack heatsink and a triple fan setup, which make up a triple-slot cooling solution. The cooler's fans, and the HellHound logo on the backplate, are illuminated.

A striking aspect of this card is that it has the same set of power connectors as the AMD reference design, with just two 8-pin PCIe power connectors for a power-delivery capability of 375 W. It's possible that PowerColor is using a common board design for both the RX 7900 XTX and RX 7900 XT HellHound products. Besides the two power connectors, we spot a switch to control the LED illumination. There's another switch toward the front-end of the card, which works as a dual-BIOS selector.

ASUS First OEM to Show Off Custom Radeon RX 7900-series Cards

Although we're over a month away from any kind of actual availability of AMD's just announced Radeon RX 7900 cards, ASUS has already shown off what is the first custom Radeon RX 7900-series cards. The two cards are the TUF Gaming Radeon RX 7900 XTX and unsurprisingly the TUF Gaming Radeon RX 7900 XT. ASUS has gone for what the company calls a 3.63-slot design and the TUF cards appear to be a fair bit taller than the AMD reference designs. ASUS has gone with larger fans, which requires a bigger cooler shroud and the company claims they provide 13.8 percent more airflow and an eight percent increase in static pressure compared to its last gen—presumably Radeon RX 6900—cards, while maintaining the same noise level.

ASUS claims to have added wider vents on the backplate to help improve airflow and to have increased the total heat dissipation area by 22.8 percent, whatever that actually means, as ASUS didn't show off the rear of its cards. The TUF Gaming Radeon RX 7900 XTX sports three 8-pin power connectors and has a 17+4 power stage design. Unlike AMD's reference cards, the ASUS TUF cards won't have a USB-C port at the rear, as the company has gone for three DP 2.1 ports and one HDMI 2.1 port. ASUS didn't reveal clock speeds and the remaining specs are as announced by AMD.

AMD Announces the $999 Radeon RX 7900 XTX and $899 RX 7900 XT, 5nm RDNA3, DisplayPort 2.1, FSR 3.0 FluidMotion

AMD today announced the Radeon RX 7900 XTX and Radeon RX 7900 XT gaming graphics cards debuting its next-generation RDNA3 graphics architecture. The two new cards come at $999 and $899—basically targeting the $1000 high-end premium price point.
Both cards will be available on December 13th, not only the AMD reference design, which is sold through AMD.com, but also custom-design variants from the many board partners on the same day. AIBs are expected to announce their products in the coming weeks.

The RX 7900 XTX is priced at USD $999, and the RX 7900 XT is $899, which is a surprisingly small difference of only $100, for a performance difference that will certainly be larger, probably in the 20% range. Both Radeon RX 7900 XTX and RX 7900 XT are using the PCI-Express 4.0 interface, Gen 5 is not supported with this generation. The RX 7900 XTX has a typical board power of 355 W, or about 95 W less than that of the GeForce RTX 4090. The reference-design RX 7900 XTX uses conventional 8-pin PCIe power connectors, as would custom-design cards, when they come out. AMD's board partners will create units with three 8-pin power connectors, for higher out of the box performance and better OC potential. The decision to not use the 16-pin power connector that NVIDIA uses was made "well over a year ago", mostly because of cost, complexity and the fact that these Radeons don't require that much power anyway.

AMD Radeon RX 7900 XTX RDNA3 Prototype Leaked, Confirms Reference Cooler Design

Here's what is possibly the very first picture of an AMD Radeon RX 7900 XTX RDNA3 graphics card. AMD engineering samples and prototypes tend to use red color PCBs, which is what this card is. It reveals what could be the final design of the reference cooling solution for the card, and it seems to match the teasers the company put out in its Ryzen 7000-series launch event.

The RX 7900 XTX cooling solution design builds on that of its predecessor. The card itself has 3 slots thick, but slightly longer than the RX 6900 XT. The aluminium fin-stack heatsink is bulkier than the one on the RX 6900 XT cooler, and appears to be bursting out of the vents. It stretches out to the edges of the cooler shroud. The bulge toward the tail-end could be housing the tips of the heat-pipes. The prototype card has two 8-pin PCIe power inputs. There's no backplate, because the PCB has several headers in place for diagnostics and developmental use by AIBs and OEMs.

AMD Radeon RX 7000 RDNA3 To Launch Early December

AMD's next-generation Radeon RX 7000-series graphics cards based on the RDNA3 graphics architecture, are expected to launch in early-December 2022, according to greymon55, a reliable source with AMD leaks. The cards will be unveiled at a media event to be held on November 3, 2022, with market availability following a month after (between 1st to 5th December). The company is expected to take a top-down product-stack release cycle similar to that of NVIDIA, with the release of two of its top SKUs, the Radeon RX 7900 XTX and the RX 7900 XT. Both these cards are based on the 5 nm Navi 31 MCM GPU. This will be AMD's first client-graphics MCM GPU with more than one logic die. The company has a decade of experience with MCMs, but past generations have been one logic die surrounded with on-package HBM. Navi 31 has on-package logic chiplets, but discrete GDDR6 memory, like most other GPUs in the market today. It's rumored that the company is targeting a 100% performance uplift over the previous-generation, which means team-red is on the prowl to compete with NVIDIA's fastest SKUs, including the RTX 4090 and upcoming RTX 4080.

AMD Radeon RX 7900 XTX to Lead the RDNA3 Pack?

AMD is reportedly bringing back the "XTX" brand extension to the main marketing names of its upcoming Radeon RX 7000-series SKUs. The company had, until now, reserved the "XTX" moniker for internal use, to denote SKUs that max out all hardware available on a given silicon. The RX 7000-series introduce the company's next-generation RDNA3 graphics architecture, and will see the company introduce its chiplets packaging design to the client-graphics space. The next-generation "Navi 31" GPU will likely be the first of its kind: while multi-chip module (MCM) GPUs aren't new, this would be the first time that multiple logic chips would sit on a single package for client GPUs. AMD has plenty of experience with MCM GPUs, but those have been single logic chips surrounded by memory stacks. "Navi 31" uses multiple logic chips on a package; which is then wired to conventional discrete GDDR6 memory devices like any other client GPU.

The rumored Radeon RX 7900 XTX is features 12,288 stream processors, likely across two logic tiles that contain the SIMD components. These tiles are [for now] rumored to be built on the TSMC N5 (5 nm EUV) foundry process. The Display CoreNext (DCN), and Video CoreNext (VCN) components, as well as the GDDR6 memory controllers, will be built on separate chiplets that are likely built on TSMC N6 (6 nm). The "Navi 31" has a 384-bit wide memory interface. This is 384-bit and not "2x 192-bit," because the logic tiles don't have memory interfaces of their own, but rely on memory controller tiles shared between the two logic tiles, much in the same as a dual-channel DDR4 memory interface being shared between the two 8-core CPU chiplets on a Ryzen 5950X processor.

Seasonic Lists Radeon RX 7000 Series in Wattage Calculator

Seasonic has recently updated their wattage calculator tool to include the unreleased AMD Radeon RX 7000 series however it is currently unknown if the power information comes directly from AMD. The RX 7900 XT and 7800 XT are both listed as requiring a 750 W power while for the RX 7700 XT a 650 W supply is recommended with these values all aligning with those of the corresponding Radeon RX 6000 models. The RDNA 3 architecture of these new graphics cards is expected to increase performance by up to 40% according to recent leaks with AMD confirming they are targeting a 50% performance/watt increase over RDNA 2.

AMD RX 7900 XT Reportedly Brings 40% Performance Uplift Over RX 6900 XT

AMD's RDNA 2 architecture provided a significant performance increase for the company and allowed them to re-enter the high-end GPU market. AMD hopes to keep this momentum up with the launch of its RX 7900 XT card featuring the RDNA 3 architecture which will reportedly bring a further performance increase of at least 40% over the RX 6900 XT with internal projections as high as 60% - 80%. The RDNA 3 architecture is expected to feature a chiplet-based design with discrete I/O and compute dies similar to Ryzen processors. AMD has officially said they are targetting a 50% performance/watt increase over RDNA 2 with the new architecture which lends weight to this rumor. The RX 7900 XT is not expected to launch in the foreseeable future so take these rumors with a healthy dose of skepticism but if these performance improvements are anything close to accurate AMD could have a winner with RDNA 3.
