Radeon VS Radeon Pro Performance

[Perkka]

I've noticed something that i feel is kinda odd.
But it seems like there is something that caps the performance on non Apple cards that should perform the same

For example if we look at Geekbench Metal scores

AMD Radeon VII gets 54814 points
VS
AMD Radeon Pro VII gets 94556 points
and
AMD Radeon Pro II gets 97701 points

The Radeon Pro II should get a few percent higher score since it got 64CU instead of Radeon VII 60CU. but what is this discrepancy between Radeon VII and Radeon Pro VII


We got the same with 14nm Vega:

Vega 64 53007 points
VS
Vega Pro 64 64118 points


Vega 56 51159 points
VS
Vega Pro 56 61485 points

Also looking at Navi:

AMD Radeon RX 5700 XT 44038 points
VS
AMD Radeon Pro 5700XT 74805 points


All those cards should have more or less the same score but they do not.

So is there a way to trick osx to think it's the official apple version to get extra performance?

Yes, this really is interesting, I am also wondering whether this could be done by some FrameBuffer injection or Kext ...

According to the following, the Radeon VIIs perform about as expected when compared to the Vega IIs.

It simply is a Geekbench issue. Try other compute benchmarks (for example Luxmark) and you will notice the PC cards perform as expected. Also, there is no "AMD Radeon Pro VII" or "AMD Radeon Pro 5700XT".
