becouse this is cpu testThey have to do the CPU testing with a 4090 in 1080p or even lower. Like every other benchmarking site. Otherwise the charts would be very boring for the readers.
In 4k I.e., one would think of the 9700x and 5800x3D as the same, almost to the point identical in gaming performance. The same goes with a GPU like a 3060 12GB or RX 6600 8GB, which seems more proportional to 1080p. So a CPU review needs to artificially create a CPU bound situation, and the 4090 with it's power is a godsend for that, even if it doesn't reesemle a real life scenario for a 4090.
So if you want to have some benchmarks with differences to talk about, you need to tolerate that. If you game at 4k or even 1440p, and or if you use a GPU <4090, like a 7800xt or 4070 or even slower ones, differences between CPUs will be smaller, of course depending in the games. Because then the situation changes to a GPU bound real world scenario, which is where most of us are or want to be in reality, and then even a slower CPU seems to perform on par with faster ones. But those reviews are telling us something important, nonetheless: How those CPUs will presumably age with new hardware (GPUs) and new software (games).
For example: Do prepare for lots and lots of 'absurd' 1080p reviews with the even mightier 5090, once it launches. Seems absurd, okay. But it's logical. Because you need the fastest GPU and lowest resolutions to clearly show the differences in CPU performance in this context. And a 5090, and that's the point, will show greater differences of the CPUs than todays flagship, the 4090. Those reviews will provide us with a better view on what type of silicon will age better with the faster GPUs and more demanding games of the future.
that is way I do not need better cpu than my 5800x3d becouse no benefit in 1044p or higher
gpu is most inportant
