New specifications for AMD’s upcoming next-generation “Navi 3x” GPUs, which will be based on the RDNA3 graphics architecture have been shared by Twitter user Greymon55. These new specifications contradict previous reports we’ve had on these GPUs. The new specifications show a more toned-down outlook. The flagship GPU, the Navi 31 is now said to have 12288 Stream Processors, not 15360. It will also have 48 WGP (workgroup processors), 12 SA (shader arrays), and 6 SE (shader engines). Even though these are toned-down specifications that are still a 140% increase in Stream Processors over the Navi 21. These GPU is expected to power cards that will succeed the Radeon RX 6800 and RX 6900 series.

The next chip is the Navi 32 which instead of 10240 Stream Processors will only have 8192 with 32 WGPs, 8 SAs, and 4 SEs. Then finally there is the 33, which appears to have the same specifications are earlier reported with 4096 stream processors, 16 WGPs, 4 SAs, and 2 SEs.
This is one of the first major update to the rumored specifications that we’ve had in about a year. Do keep in mind we are still months away from the launch of RDNA3 GPUs. For a break-down of the chips here is a nice graph compiled by VideoCardz.
