Sure if you only test examples using certain titles then it will favour one brand over the other. For example if you only tested a few specific RT titles, my 6900 XT is faster than my 3090. That’s why it’s important to take a balanced view and test over a range of titles. That Computerbase article is quite revealing I think.
That's exactly right. The strengths and weakness or how good/bad a GPU shouldn't be based on a handful of games. As you say, certain games favour one brand or another. That attitude should be applied in all Graphic card discussions going forward. That's including the RT debate and the Vram debate. One game been better on GPU than the other doesn't mean anything.
