Think about it... CD = 44Khz, DVD= 96Khz, PC computer > 1GHz.
The clock responsible for the jitter level is an independent hardware device (provided by the soundcard or provided by the motherboard for the USB controller for USB adaptive mode), irrelevant to the CPU clock. CPU cannot influence the final clock directly (except for some hardly predictable induced power supply noise due to CPU consumption fluctuations).
