Out of curiosity what jobs need a good CPU but also can't take advantage of a good GPU?

It seems like most of the high performance numerical computing software today is GPU-accelerated. If performance for your job is super important, why isn't your software GPU-accelerated?

I might just be naive but it's honestly hard for me to imagine why anybody would need a good CPU and not also want a good GPU.

I work on static analysis (points-to analysis) that does not use any GPU at all and is mostly single threaded.

Static code analysis on 100s of mb of code. Pins my m1max for 3min, my 2015 for 15-20ish.

Because here in the real world software isn’t GPU optimized in many cases.

Since this is HN... compiling.

Good point, not sure how I didn't see that, I'm a software engineer too.

Compiling is IO/RAM bound. CPU has impact but not much for most cases.

Nah, I only see minimal difference when building on a ram disk (source tree copied there too) compared to a nvme SSD.

You clearly aren't writing c++ :D
