Now, first things first. I should give a shout out to our friends over at VCZ who have also managed to track down this result. The database entry is for 3DMark 11 “Performance” and shows a yet unidentified “Generic” AMD GPU with 32GB of HBM2 vRAM clocked at a whopping 1.25GHz, the highest clock we’ve seen on HBM to date.
Now, the most interesting part here is the GPU clock speed. If the reported figure is to be believed this early engineering sample of Vega 20 is running at exactly 1GHz. It’s possible that this is because 3DMark is misreporting the clock speed. However, if we go back to really early Vega Frontier Edition database entries we find that when 3DMark fails to read the clock speed it simply reports it as 0, rather than 1GHz. And misreadings of the UEFI data have also led to misreadings of the HBM2 vRAM by 3DMark. We don’t see any of that with this particular Vega 20 entry.
