Just upgraded from an i5-2500K at 4.4 GHz to an i7-7820X at 4.8 GHz. All benchmarks show that the processor is considerably more powerful than my 2500K.
The issue? Every day use seems sluggish. I've narrowed the problem down to the processor spending almost all of its time at 1.2 GHz - even up to ~15% utilization. My 2500K was quick to boost up to 4.4 GHz from 1.6 GHz, but my 7820X just sits there until a massive load gets dropped on it.
Disabling energy efficient features (C-states, EIST, Speedshift) locks the CPU to 4.8 GHz and makes the issue go away, but it also causes my idle power consumption to almost double.
Anyone ever dealt with an issue like this? I'd rather not have to keep an instance of Prime95 running on a single thread to make my computer feel "snappy."
