*** GPU Hierarchy ***

Do cards have the same ranking running in Linux? Not absolute performance, which I expect to be different. But the ranks ie 1st running in Windows still 1st in Linux for a given task.

I'm interested in getting a card for AI in linux.

I ask because stable diffusion performance is much higher for AMD on linux.
No this is purely compiled based on gaming performance.

Linux performance should be similar, and you'd expect ai performance to be similar in that more powerful cards should be better at it, but there are a few intricacies that may affect ai, e.g. which Cuda version is supported for Nvidia cards (e.g. old high end cards might not even be able to run it, as don't support a new enough version) and amount of vram (e.g. new low end cards might not have enough vram for the models you require)
 
Was looking at upgrading my nieces Xbox One X to the Series S
But this charts shows the old Xbox One X as being faster then the newer Xbox Series S :(
I've no experience with the Xbox side of things (I've got a PS4 and PS5) but the theoretical specs at least list the One X GPU at 6 TFlops Vs only 4 TFlops for the Series S.
 
Shouldnt the 7900xt be in tier D?

And shouldnt the RX 7900 GRE be in tier E?

From the latest rankings here, that seems pretty clear:


I use several sources to make a decision, and one of the other sources I use still reinforces the position of where they currently are.

The biggest difficulty is that by assigning "tiers" rather than a position on a graph, you inherently have to group cards together. Some of the tiers are particularly odd in that there might be 15% difference between the "top" and "bottom" cards in a tier, but yet they are probably only 2-3% faster or slower than the cards in the next tier up or down... you have to draw a line somewhere.
The 7900XT and 7900GRE probably fall into that trap too, as the 7900XT is definitely the slowest card in Tier C, but probably has enough of a jump over cards in Tier D that it feels wrong to be there.

Personal view is 3-4 tiers if you are somewhere in the middle of the list. If you are nearer the top then 2-3 tiers should be your aim.

The only 1 tier move that really made sense would be from say a 4080 to a 4090, and that was simply because the performance increase from a 4090 was so good there probably should be an empty tier below it :)
