I was able to recently get a Radeon 6700 XT 12 GB and put together a third gamer config entirely based on AMD hardware.
Warning ! This is a test in real use, ie each config records its own video using Streamlabs, in ultrafast CPU encoding. This is important to me because it really reflects the way I use these 2 PCs, where most testers try graphics cards on identical PCs, with the same CPU.
So I wanted to compare the Intel Core i9-9900KF monster supported by its RTX 3070 to my new Full AMD config, with a Ryzen 9 3900X, which benefits from Smart Access Memory, giving it a serious boost. In use, that is to say in stream or in recording during the game, the AMD config literally explodes, to my surprise, the Intel + nVidia offer, however very swift. Right now, it's Assassin's Creed Valhalla that's occupying my evenings, and it's very clearly optimized for AMD hardware. Here is what I was able to measure, the framerate goes from single to double.
