I understand why reviewers don't review at these resolutions given what
@Brent_Justice mentioned. From the numbers I've seen at the higher resolutions I am not impressed enough to consider upgrading my 7800X3D since I game at 4K.
Because you are GPU-bound at the higher resolutions.
But what happens if you upgrade your GPU, instantly the CPU choice will show a difference, and it becomes more pronounced and more pronounced over time. In the goal of reviewing CPU performance, we have to test in a way that does exactly that, because the goal is to find out if the CPUs offer anything in terms of gameplay performance improvement over another, this will tell you which is better suited for gaming, and how they will react to situations that are CPU bound in games, and that would hold back your GPU.
Keep in mind that different areas in games do affect CPUs differently, and thus in one part of the game you may be GPU bound, but come through a village or town with a lot of NPCs, and suddenly that CPU is holding your GPU back, reducing its utilization. Then there are badly optimized games that are also more CPU bound, even on fast GPUs, and the GPU just simply has less GPU utilization. A CPU review, focused on CPU performance, can tell you which CPU handles those areas better. But we have to put the system into a CPU-bound scenario, else we aren't testing the CPU, but testing the GPU instead.
Watch Daniel's video I posted first, above. It explains the difference that the reader/end-user is looking for, versus the question the reviewer has to answer. I cannot tell you how your system performs with each CPU, I cannot test every possible scenario and variable, the only thing I can do is test CPU performance, and make sure things are configured to do so. CPU will matter at 4K, again watch HUBs last video, on that topic. Seriously, the videos I just showed above explain this entire situation very well. There's a lot of misunderstanding in regards to what's expected.
