Looks quite a bit faster than a 5800X (https://www.mersenneforum.org/showpost.php?p=596448&postcount=857) at larger FFTs though!
Timings for 4096K FFT length (8 cores, 1 worker): 2.26 ms. ...

If you're going with Zen 3, I'd suggest going with 3600 RAM, especially with 8 cores. That's an extra 12.5% memory bandwidth, and 8 cores will definitely use it.
Thinking of getting the 5800X3D?...

I'd probably go Intel for power efficiency, performance, and price, as far as 4 core goes.
If going AMD, you definitely want Zen 3, and outside of mobile, it's 6+ cores. There is the 5300G, but...

I don't think it would work out well. That's 6 cores per memory channel, usually at 2933 or 3200, so very memory starved. The 12 core 2920X would be a better fit. But I still wouldn't buy one these...

You can get actual stats if you like. Here is mprime on my 6 core desktop running for seven days, with a bunch of background processes like Steam, Discord, a few browser tabs, and so on running:

The overhead comes in context switching. That happens when you make a system call, for instance, or the OS schedules a different process to run. Prime95/mprime hardly causes any context switching.

For what's it's worth, several years ago I went and did all the unrecorded work in situations where we had a record of "no factor to 2^62" and "no factor from 2^64 to 2^65" for exponents below 100M....

You may be running into memory bandwidth saturation. I'd see that frequently enough with old c3 instances. Cloud providers also tend to use high core count CPUs, with 4 or more cores per memory...

Simple as that. webp is a format that's been around a decade and is widely used for images on websites.
