I maintain that both Radeon RX 9070 XT and RX 9060 XT 16GB are great graphics cards. However, part of me mourns the RDNA 4 GPUs that never were, the dies that may have gone toe-to-toe with GeForce RTX 5080.
I’d love to see AMD make a return to the high-end market, and I know I’m not alone in feeling this way. Thankfully, leaks indicate the company plans to do just that with its next-generation architecture, RDNA 5.
YouTuber Moore’s Law Is Dead (MLID) has shared alleged specifications of two RDNA 5 GPUs: AT0 and AT2. The leaker claims AMD is also working on a third die, AT3, but information on the silicon is scarce.
Let’s start with AT0, the flagship. According to documents shared by MLID, the GPU will feature an enormous 184 CUs (Compute Units), far more than counts previously rumoured. For context, Radeon RX 7900 XTX with a full-fat Navi 31 die only had 96 CUs to its name.
Unfortunately for consumers, that particular configuration appears destined for the enterprise market. That said, an ‘AT0 XL’ variant with 154 CUs appears within the specifications chart that should find its way into a desktop graphics card.
Further information on AT0 details that the GPU will sport a maximum TDP of 600W, with AT0 XL dropping to 380W. The full-fat die will have a 512-bit memory bus, whereas cutdown versions will shrink down to 384-bits.
Shifting focus to AT2, we’re staring down up 64 CUs, as AMD currently plans to ship three desktop gaming variants. MLID claims this is the midrange success to Navi 48, and at least one of these die designs will likely appears in PS6 and/or next-gen Xbox.
Other notable specs include the use of GDDR7 memory modules across the entire stack, all running at 36Gb/s. This would make RDNA 5 VRAM faster than GeForce RTX 5080, which boasts the fastest chips at 30Gb/s.
Excitingly, AMD may finally bid farewell to 8GB buffers with RDNA 5. The document MLID provides lists AT0 XL as having 36GB of VRAM, with AT2 variants rocking 12-18GB of memory. Looks like AMD is hearing consumer preferences for more VRAM, through Radeon RX 9060 XT 16GB, loud and clear.
Given how recently AMD launched RDNA 4-based graphics cards, next-generation offerings are understandably a few years away. More specifically, the table places ‘Wave 1’ (AT2 XT and AT2 XL) in April 2027 at the earliest.
MLID states that this information comes from some of their most reliable sources, with multiple confirmations. However, as they rightly highlight, much is subject to change given how early the GPUs are in their development cycle.
Much as I’m taking all this information with a pinch of salt, I can’t help but get excited at what AMD seems to be cooking up. Of course, the devil’s in the performance, particularly in how these cards will compared to GeForce RTX 60 Series offerings from Nvidia.
In the meantime, AMD may need to scramble a counter-offensive to GeForce RTX 50 Super Series cards which rumours say will launch later this year. As you might imagine, I’m doing my best to say on top of all these graphics card rumours and you can too by visiting the Club386 Google News page and dropping the site a follow.
