Hardware / Intel Adler Lake i9-12900K CPU - poor performance.
« on: 2022-03-08, 03:15:39 »
Hi All,
I just got a system with the following spec:
i9-12900K Processor, 128G RAM, 2TB SSD, RTX3080 GPU on Windows 10 Pro Build 21H2
When I kick off a render, I see that only 8 of 24 of my cores go to 100%. On my old machine (Core i7 7900X), I don't have this problem - all cores go to 100%.
I know that the new i9 CPUs have some p-Cores some e-Cores, however it should still hit 100%. I thought this was an issue with CPU core parking, so I used a bitsum's "ParkControl" utility to force-unpark all the cores. Still, I only see 8 of the 24 "cores" showing full usage. Overall CPU usage is about 40-50% max.
At the same time, I ran IntelBurnTest for testing. All of the cores straight away shoot up to 100%, and Overall CPU usage shows 100% as well.
How can I get Corona to use 100% of the CPU?
