The recent Intel desktop processors have a “base” frequency and a “max turbo” frequency. On the i5-12600k I believe the base is 3.7 and the max turbo default is 4.9.
With various settings you can force them to always run at the “max turbo” frequency, and with many motherboards (including the Asus Prime Z690) you can pretty reliably overclock them higher to 5.1 or 5.2 gHz if desired.
The system I’m on right now is an i5-12600k that I have running at 5.0gHz all the time.
My experience with audio on Windows PCs is that you get much more benefit from forcing them to always run at the “max turbo” speed than by pushing the overclocking.
The simple reason is that in the name of saving power Windows will slow your CPU speed down to the “base” frequency under light load, and even shut down cores if you let it. The nature of running “real time” audio is that the loads will on average tend to be fairly light, so your CPU will tend to run at “base frequency” (or at least drop to it frequently) if you let it, then you’ll get glitching if the base frequency wasn’t quite enough to handle one sample buffer.
In the gaming world the tradeoffs tend to be different. There you might be better off letting the CPU run at 3.7GHz most of the time but overclocking the “max turbo” to 5.5GHz, but most systems will only be able to sustain the thermal load at that speed briefly before thermal throttling happens. In my experience that kind of thing doesn’t help audio. Your glitches will happen when the CPU is running below top speed, and the system won’t decide to ramp up the speed until after the glitch has happened. Then it’s too late.
Bottom line, I’m “overclocking” mine from 4.9GHz to 5.0GHz, but the overclocking part is less important than forcing it to not drop down to 3.7. You can force windows to run at “max turbo” all the time without getting into more elaborate “overclocking”.
