AMD Radeon RX 6000 graphics cards will be introduced in a month, but gradually more and more details are coming online. For example, today there is a confirmation of previously appeared information about the number of CU blocks in the new generation of graphics processors.
So, Navi 21 will have 80 blocks, Navi 22 – 40 blocks, and Navi 23 – 32 blocks. However, we do not know yet how many thread processors we are talking about. If the ratio remains unchanged, the GPUs will get 5120, 2560 and 2048 thread processors in the same order. However, Nvidia has already surprised us by doubling the number of CUDA cores per compute module, so we have to wait for details.
And if you’re not impressed with the 5120 streaming processors against a background of more than 10,000 CUDA cores on the RTX 3090, the source also shows an increased GPU frequency of 2050 MHz for Navi 21A and 2200 MHz for Navi 21B. These are very high frequencies, so the new AMD cards may well “go” to them. Moreover, for the Navi 22 the frequency indicated is equal to an incredible 2500 MHz, which is hard to believe, but everything can be.
In addition, in the code of the AMD ROCm 3.8 set there was found a mention of Navi 31 GPU with the same 80 CU blocks. What kind of GPU is this and why its characteristics already exist, despite the fact that Navi 21 has not even been introduced yet, it is unclear.
