There is Threadripper and Epyc for those who need a faster CPU or better to say with more cores.
About GPU, rumours whisper that the next GPU will be like TR, with a lot of chiplets, yeah probably RDNA5.
Don't expect much this is 3D test, it suppose to test your video card, not your CPU.

I have a UPS, but it didn't help when the PC reset by too high/unstable CPU/GPU overclock :D
