Power Tests
We've made mention that the two Core i9 chips are almost identical. It's curious the 10850K draws 26W fewer from the mains. Looking into it further, it runs at a marginally lower voltage - 1.2V vs. 1.247V - which helps explain the power saving.
Gaming is mostly driven by the RTX 2080 Ti graphics card. Reason enough we don't see a large deviation between results.
