Looks like we have new data on Navi 2X graphics processors. AMD Navi 21 – 80 CUs, Navi 22 – 40 CUs, Navi 23 – 32 CUs The speciations of the Navi 21 and Navi 22 were already ‘confirmed’ by AMD through ROCm 3.8 software update earlier. The data was pieced together by a Redditor […]
This GPU would allegedly feature up to 80 Compute Units (5120 Stream Processors if each CU has 64 cores). The variant listed in macOS11 appears to have a boost clock at 2050 MHz with Navi 21A variant and up to 2200 MHz with Navi 21B variant.
With a boost clock of 2200 MHz, the Navi 21B would have a shader performance of 22.5 TFLOPs. For comparison, with NVIDIA’s new dual SM architecture, the GeForce RTX 3080 graphics card has a maximum FP32 throughput of 29.8 TFLOPs.
Navi 22 – Navy Flounder
The mid-tier GPU in a lineup appears to feature 40 CUs, so just as many as Navi 10. Therefore, the GPU is expected to be an RDNA2 version of mid-range graphics for the upcoming RX 6700 series. The GPU is listed with a (maximum) GPU clock of 2500 MHz, so even higher than Navi 21.
Navi 23 – Dimgrey Cavefish
The entry-level GPU called Navi 23 is also listed in the firmware. Judging from the data collected by the Reddit stblr, we can conclude that the full number of CUs is 32 (so around 2048 Stream Processors). The frequency charts are not featured in the firmware yet.
We can already say that AMD will gain in efficiency this time ?
