What brand card are you running? I struggle to get my Gigabyte Aorus Master 6900XTXH above 200k on GB6. This is the most i've gotten, and it fluctuates drastically between 175k - 200k.

The most i get on GB5 Is around 180k, drops as low as 155k. Where i've seen others with the same card get way higher metal scores with GB5 (GB6 would be even higher).. Is there something wrong my card? Or does this have something to do with my OC/MacOS config?

What's your card max out at on GB5?

Thanks

MSI Radeon RX 6900 XT GAMING Z TRIO.yes can't rely on GB Benchmarks are up and down on all versions.

I suggest updating to modern GeekBench, ensuring the version you have is the same on both (!) and then redoing your test.

That said, you’re getting 1/2 what you should be getting. (Edit: Nope; I am thinking of metal; can you share your metal score pls?) What happens in 13.2.1 ?

even later edit: 186k in GB6 metal. That’s odd; I’m getting 224k in GB6 metal on a 6900xtxh.

Both Windows and Mac were using Geekbench 5 but not exact same release - Windows 5.4 and Mac 5.5.1. I can re-run tonight when I'm back in front of my rig.

Metal score

Geekbench 6 scores higher than 5. I can re-run all the tests using GB6 but I'm assuming I'll see a similar difference.

Is this before or after first sleep?

I tried before and after sleep. No change.

When I had my Vega56, my scores were nearly identical between Mac and Windows and in line with expectations for the card.

Thanks everyone for the suggestions, keep them coming!

With what GPU?

Separately, I suggest that when you see this GPU issue that you also (in GB6; let’s all flip to the modern version…) run several CPU tests and see if your CPU scores similarly move around, to try to isolate the issue to ‘just GPU’ vs. both.

I’ve not noticed mine varying.

I just tested both Win11 and Monterey 12.6.2, same result, Windows has a higher score.

I'll run more tests but the one i did, showed me a slight increase in single core performance but quite a hit in multi-score when compared to GB5.
GB5 Multi - 25k
GB6 Multi - 16k. <--?

One cannot compare across versions, the intent is for you to run gb6 in both platforms and compare there.

Tested GB6 across both platforms, same version, 3 tests on each one after another, Metal x3 , OpenCL x3, Cpu x3 (Mac), Vulcan x3, OpenCL x3, Cpu x3 (Win11), so 18 tests all together.

Results were very similar with little variation to each other (as you stated). More noticeable between OS's.

My Results;

OpenCL

Vulcan/Metal

Note: i updated to the latest AMD driver (released Feb 2023) and now my metal scores are staying around 180k mark. I think there's something going on with my card or config, according to GB6 results, i should be reaching over 200k on GB6. Anyone have any ideas?

I'm one of the unlucky guys who got a RX 6700 XT, which is not supported by macOS. I dual boot Windows (for gaming) and macOS (for work). Thus, I also bought a secondary GPU just for macOS a RX 560. Back then (in March 2021), it was the only option. Now with the introduction of the 7900 XT in Germany, the GPU prices are significantly dropping:

RX 6600 XT: 265€
RX 6800 XT: 600€
RX 6900 XT: 690€

RX 7900 XT: 849€ - not supported by macOS

So my idea is to replace my dual-GPU setup, for better desktop performance (I use a 2x 4k monitors). My questions are:

1. Should I wait for 7900 XT driver support that might never come?

2. Is there any reason to panic, because sooner or later the RX 6800/6900 XT will be sold out and the only option to get one will be used from eBay? Or should I just wait and chill, the prices will continue to decrease.

3. Should I get a 6900 XT because it is just 90€ more? Is it worth it, considering the higher power consumption?

@root2
I don't expect support for the 7000 serie but who knows, maybe Apple has different opinion.
Only 90€, I prefer 6900 XT, but really both 6800 and 6900 are great cards for macOS (and Windows).
