    Dr-Noob here. Created an account just to comment on this post. I appreciate all of your comments.

    For the ones who think that cpufetch uses lscpu (especially the one who wrote the title of this post), please see

    About the peak performance, nezirus, the purpose is to have a quick look of how powerful a CPU is supposed to be. Peak performance does not measure the real performance of a CPU but it is a rough estimate of it. The peak performance is one of the distinguishing marks of cpufetch and is one of my favorite fields of cpufetch. Concerning the fight between Gold 6238 and EPYC 7702P, is not the other way around. If you are able to use the full power of the CPU, Gold is much more powerful. However, in a real program, this is not always true. For more information about the peak performance, see There you will understand how peak performance is calculated and how it works.

    Thank you very much for your "text screenshots", I really like to see my program on all this variety of hardware!
