The Navi 23 silicon in the AMD RX 6000 is called Dimgrey Cavefish

Yesterday thanks to the open source ROCm drivers for Linux operating systems we met Navy Flounder. It was unclear if it would be a mid-range or high-end Navi GPU, but today it seems to be clearer. Now we know the Dimgrey Cavefish graphic that would correspond to AMD Navi 23, or what is the same, the simplest solution of the new RX 6000.

If yesterday it was thanks to the ROCm drivers, today we know Dimgrey Cavefish thanks to Mesa 20.3-devel. Thus we already know the code name of the silicon for the new AMD RX 6000 of RDNA2 architecture. Sienna Cichild corresponds to Navi 21, Navy Flounder corresponds to Navi 22 and finally Dimgrey Cavefish corresponds to Navi 23.

Dimgrey Cavefish is the codename for the Navi 23 silicon for the AMD RX 6000

The official presentation of the RX 6000 is set by AMD for next October 28. As usually happens, a month before, more or less, different data from the graphs begin to filter. These charts will require support at launch, so it is normal for the software to start adding information from these charts.

Currently it is pointed out that RDNA2 will continue to maintain 64 Stream Processors for every 1 Compute Unit. This could change, at the moment we do not have clear references, since only the number of Compute Units have been filtered. For example, Sienna Cichild has 80 CU and therefore it would have 5.120 SP (based on CU / SP ratio of current RX 5000).

Although the names are unclear, Sienna Cichild is targeting the RX 6900, Navy Flounder is targeting the RX 6800/6700, and Dimgrey Cavefish is targeting the RX 6600/6500. This is all based on rumors and speculation, we still cannot confirm or deny anything. But remember that the current RX 5000 were baptized in three different ways and in the end they came with another list of names.
