Leaker claims new AMD RDNA 5 GPU details

While the current-gen RDNA 4 architecture has been a solid performer in the mid-range, enthusiasts have been waiting for AMD to return to the high-end GPU market. Now, the first whispers of that return are beginning to surface with a new report on RDNA 5.

Hardware leaker Kepler_L2 (via Wccftech) has shared what appear to be the first architectural details of the next-generation RDNA5 GPU family, which includes a proper flagship contender. The report shows a top-tier GPU internally codenamed “AT0”, which is expected to power AMD's high-end graphics cards. This chip is rumoured to feature 96 CUs paired with up to a 512-bit memory bus, which would provide a significant performance boost to compete with Nvidia's alternatives at 4K and beyond.

The rest of the RDNA 5 lineup was also detailed, including a 40 CU “AT2” chip that appears to have a 192-bit memory bus (384-bit also possible). Moreover, there was also the smaller “AT3” with 24 CUs and either a 256-bit or a 128-bit memory bus, and finally the “AT4”, featuring 12 CUs and a 128-bit or a 64-bit memory bus.

As the leaker points out, there is no evidence that these chips have even been taped out yet, meaning these are very early architectural plans. Final specifications, naming, and so on are all still a long way from being finalised and are subject to change. However, based on what we have right now, AMD appears to have a plan to take on Nvidia's next-gen GPUs.
