Previously circulated the specifications of Navi 33 are similar to the current Navi 21, there will be 5120 stream processors (20 WGP). According to Twitter user @Greymon55
, the news shows that the number of stream processors is not that many. Navi 33 will only be configured with 16 WGP, which is 4096 stream processors. However, this does not mean that performance will decrease, and it may still be better than Radeon RX 6900 XT. Even if it does not surpass the Radeon RX 6900 XT, the performance is almost the same, which may explain the improvement in the efficiency of the RDNA 3 architecture compared to the RDNA 2 architecture.
In addition, unlike Navi 31 and Navi 32, which are manufactured using 5nm and 6nm processes, Navi 33 will use a 6nm process, Infinity Cache is 128 or 256MB, memory width is 128 bits, and it is equipped with GDDR6 memory. It is reported that the remaining products of the Radeon RX 7000 series still use RDNA 2 architecture GPUs, but they will be manufactured on a 6nm process. It seems that with the exception of Navi 31 and Navi 32 in the MCM multi-chip package, AMD does not intend to introduce the 5nm process to other products in the Radeon RX 7000 series.
It is expected that the Navi 33 core will be released soon and will be launched on the market around October 2022.
