In the new clean session, DSP load:
i9-10920X - 11%
i7-3930K - 3%

The same version of linux is freshly installed on both computers.

The CPU often has little to do with this.

It's usually the mainboard or some other component that block the flow of data for some time:

Thanks! Removed Intel Speed Shift in the BIOS and the DSP load became 3%
