%20-25 cpu overhead
everyone went crazy when zen 3 pushed %25-30 performance over zen 2
nvidia gpus with their software scheduling casually eat away %20 cpu bound performance on average compared to amd gpus and no one bats an eye
imagine having a 5800x with an amd gpu
and imagine having a 5800x with an nvidia gpu
now imagine a %25 faster r7 6800x
5800x+nvidia gpu's cpu bound performance = 3700x+amd gpu's cpu bound performance
6800x+nvidia gpu's cpu bound performance = 5800x+amd gpu's cpu bound performance
practically, if you have a 5800x you will probably be still fine with the nextgen RDNA GPU. chances are it will suck with nextgen Nvidia GPU is very HIGH. a %25 cpu increase means LOTS when CPU becomes the bottleneck. a 5800x+6800xt build can easily upgrade to a 7800xt GPu and still gets lots of benefits. 5800x already struggles to differentiate the 3070 from 3080 at 1080p due to heavy CPU bottlenecks. this means that it will fail to feed a potential 4080 that can be much faster than a 3090. this is just pure tragedy at this point
you can say you're GPU bound all you want, all modern games have intense CPU bound locations that will push EVEN a 5800x below 60 fps. reviewers are afraid of consequences so they will never, ever expose THIS part of the overhead issue. instead, they will just pick some old CPUs and come to conclusions that you're fine with newer CPUs. yet here we are, 5800x dropping below 60 FPS in CPU bound locations when playing Cyberpunk, WD Legion and many other titles when combined with an Nvidia GPU (waddaya know, ray tracing itself adds enormous CPU load) sadly i don't have the data or exact comparisons for the similar situations. wish some of the reviewers who had the idea of exposing the idea had the GUTS of actually making a comparison in CPU bound locations in such places. due to the cowardice of such reviewers, nvidia has gotten away without any bad press and the situation is forgotten altogether. nv probably paid some good cash to certain specific people to stop them from observing the situation in CPU bound locations in games (jig jig street in cyberpunk, certain locations in metro exodus ee which can drop a 3900x below 45 fps, ac odyssey with its infamous 'cpu bound' athens and many more)
all i want is a simple comparison. when 5800x drops below 60 fps in wd:legion with an nv gpu, does the same scene plays %20 faster with an amd gpu instead? no one has yet to test such a situation.
