In what is certainly the first in recent times, new rumors about RDNA3 suggest that its specifications may be small short than we expected. Usually these leaks point in the opposite direction, or at least that was the case with Nvidia’s GPUs. On the AMD front, we haven’t actually heard anything in almost six months. This new round of leaks is a revision of previous leaks. There is also the possibility that they are closer to reality than previous rumors. This is only because we are now closer to the market, so it is plausible that the new specifications are what AMD chose as the final numbers. Its RDNA3 family of GPUs is expected to launch in late 2022.

The “revised” update for AMD’s upcoming GPUs comes from a Twitter user Redfire through Video card. Overall, the new figures reduce important specifications from previous leaks by 22 percent. Previously, the flagship Navi 31 card, also known as the RX 7900 XT, was thought to have 60 Workgroup (WGP) processors with 15,360 stream processors (SP). This was reduced to only 48 WGP and 12,228 SP. This would provide up to 73 teraflops of FP32 performance on the card if the GPU was clocked at 3GHz. This is an interesting development, as it were recently reported both Nvidia and AMD were in the race for 100 teraflops. Nvidia’s AD102 matrix is ​​expected to hit the target first, but AMD may also be preparing a special card, similar to Nvidia’s Titan GPUs of the past. For context, the RTX 3090 Ti is sold as offering 40 teraflops of performance, so these next-generation GPUs will be quite powerful.

It is reported that the card under Navi 31 is on a similar diet. The RX 7700 XT (Navi 32) was previously thought to have 40 WGP and 10,240 SP, but is now rumored to offer 32 WGP and 8,192 SP. The last map, Navi 33, remains unchanged. This was also confirmed by a well-known GPU advisor Grayman55, who noted that the card will “retain the original specifications”. This card has 16 WGP and 4096 SP. We still don’t have details about the memory allocation or clock speed for these GPUs, unfortunately. Greymon55 also changed the biography of his Twitter account to reflect these updated specifications; a seemingly tacit approval of their truth.

Interestingly, Greymon55 also stated that although AMD is lowering the specifications for this family of GPUs, its performance targets remain unchanged. In fact, they wrote, they may even be taller. Unfortunately, we have no idea what this means in the real world. It is also important to keep in mind that we know that AMD’s RDNA3 GPUs will be quite complex. The best SKUs will include a multi-chip module (MCM) that takes care of TSMC’s design. It is reported that they will consist of seven chips using 5nm and 6nm TSMC processes. The flagship matrix is ​​said to be approximately 800 mm per square. For comparison, the RX 6900 XT matrix is ​​only 520 mm per square.
