Looking around, I'm seeing reports of 1.4-1.5V core voltages using Intel's stock profiles, with some even going to 1.7V. That's insanely high for a 10nm process and I'm not surprised about the degradation. For comparison, in the 45/32nm days 1.2-1.3V was the norm, with some extreme overclockers (who don't expect CPUs to survive for more than a few minutes, using liquid nitrogen etc.) hitting ~1.5V, and 1.4V was a commonly quoted safe upper limit for 24x7 operation.

This is why I think it's going to be much harder for Xeon to be affected by this, as they're normally running in a more conservative voltage settings. I don't have Xeon E-2400 to look at, but Raptor Lake should be able to do 5.6 GHz at 1.3-1.4V-ish, which should be within a safe voltage range. (even the "power hungry" w9-3495X only runs at ~1.25V during 4.8 GHz TVB, and ~1.15V at non-TVB 4.6 GHz boost.)
