How to chose a CPU (Single Thread Rating?)

Hi :slight_smile:
Let me know if I’m making a mistake here…

AFAIU modern CPUs have more cores than Yuzu can actually use (since the switch has a limited number of cores and Yuzu emulates that). This means multi-core scores in CPU benchmarks will be irrelevant if we only consider the performance of Yuzu.
So I should rather chose a CPU based on its Single Thread Rating (score) on Passmark, for instance, right?


In order for us to provide better support, we need to see the log generated by yuzu. This guide will walk you through how you can obtain the log file: Getting Log Files - yuzu

Basically yes, but with some extra steps.
Make sure to look for at least 6 real cores CPUs if the budget allows, so stuff like the 10400, 11400, 12400, 3600, 5600, etc are the price/performance sweet spot for yuzu.
The PCIe version and RAM clock speed also matter for performance, so you may want a 5600 to get the best of both options (Intel locked CPUs won’t let you run 3600MHz RAM for example).

Thank you so much :smiley:

Could you elaborate on “The PCIe version and RAM clock speed also matter for performance”.

What about Alder Lake? good? bad? (e-cores etc…).

Would a 12600 be any better than a 5600? (on Passmark, it has a similar CPU Mark but a higher Single Tread Rating)

Alder Lake seems to provide the best performance, but yuzu and most emulators face issues with the e-cores. It’s a gamble on how much time it will take to solve those.
