Big Sur benchmarks
Please find my Geekbench OpenCL and Metal benchmarks. There is improvement in Geekbench, but in Luxmark and GFXBench Metal the results are predictably the same as before because they were already optimal.
@craftsman, is this consistent or one-off?
@mac_editor, consistent with the usual margin of error. This is on external display only and clamshell mode, just in case anyone wonders about the previously reported issues with multiple displays when running Geekbench.
So Geekbench GPU scores on macOS seem to be related to the resolution of the external monitor, which makes absolutely no sense since the tests are performed off screen in memory only.
Big Sur beta 3
5700XT with Eizo 1200p display - circa 60000 points
5700XT with internal retina display only - circa 42000 points
5700XT with external 4K display - circa 33000 points
As the onscreen resolution increases the scores go down.
When Geekbench gives you three wildly different scores... for the same card.
Big Sur beta 4
Geekbench the same.
GFXBench has lost 30% performance in offscreen Aztec Ruins. I'm getting around 130fps now. Used to get circa 200fps in Mojave and Catalina.
Unigene Valley has lost 10%. Now getting about 2950 points. Used to get about 3300 points.
DisplayPort output suddenly stopped working. Big Sur will detect the display and then turn it off after a second before it displays an image there.
Solution if this happens to you : Choose the reset option in the display's settings. Clear everything.
