I know, I know. Another comparison. I was curious how the MacBook will perform for video editing scenario.

2019 Mac Pro 16c (Vega II + RX 6900 XT OC)

2021 MacBook Pro M1 Pro (32GB RAM)

I was surprised that the Xeon would beat the M1 Pro in 8K CPU handling, but lose in 8K Metal? I thought it would be the other way around.

Those are great results. I'm sporting 2 GPU in there, but with the Vega II as my main display just because it works better with the Pro Display.

When I switch to the RX 6900 XT OC, this is what I get. We practically have similar specs on the 7,1 so not sure why the 4320p60 BRAW 3:1 on the CPU is not producing a check mark.

I didn't realise the two 32" displays (one running at 6K and the other at 4K) are taxing the GPU. So if I remove the Pro Display XDR from the RX 6900 XT, I get higher results.

Asus PG32UQ 4K display only (without the XDR) connected to the RX 6900 XT:

With both Apple Pro Display XDR at 6K + Asus PG32UQ at 4K:

Here's an old test I dug up with the Apple Pro Display XDR at 6K + LG 27UK850-W at 4K (also on older 12.3.1 OS):

Goes to show how much displays do tax the GPU.

Displays do tax the GPU as you say, plus geek bench updates change things. the bench mark its self is not that great, you can run it at different times and scores can vary by thousands.

The apple drivers are not updated like windows versions, just recently OGL drivers have had a big boost in windows but OSX drivers seem few and far between for updates. Plus i don't think Apple will want to boost AMD drivers much as Apple silicon will look worse against AMD.

Its a shame AMD are not allowed to release OSX drivers direct as they do for windows. we might well get better performance.

I have no idea why 4320P60 gives you a X in the result, unless its a display issue it can't produce.

But very good scores, and close enough for same spec machines.

Yeah, it's all about the quality of the GPU drivers. I re-ran the RAW Speed Test with the Vega II and I get even higher Metal FPS than the 6900? lol

Apple is crippling AMD drivers altogether from it's true potential.

Still unsure of my CPU. Probably also taking resources for the two displays is all I can think of.

Black magic isn't that reliable lol every time is different same as geek bench can vary by thousands every time. but apple drivers sit way behind windows version's for sure. I don't think apple want AMD cards slaughtering the new M chips to much.
