Is the Core i9-12900K worth mining on?
The Core i9-12900K earns about $15.37 per month — that ranks #19 of 119 CPUs in the FlowHash profitability ranking.
In efficiency (66 H/s per W) it trails most models in the catalog. Income covers electricity only at rates up to $0.11 per kWh, so the Core i9-12900K pays off only with cheap electricity.
The catalog hashrate is a FlowHash estimate: the app shows the exact value after launch, and in the calculator you can replace it with your own measurement.
The CPU mines in the background and does not get in the way of the GPU: in FlowHash you can mine Monero on the CPU and Pearl on an NVIDIA RTX GPU at the same time.
