Intel trusts the Core i9-10900K processor, which it calls the most powerful. The processor goes up to 3.7 GHz as normal frequency and 5.3 GHz at maximum frequency.
The processor runs at 125 W as normal operating power. In 100 to 100 uses, it can go up to 350W. For this reason, you must use a liquid cooler cooling system.
When the processor was overclocked, it set a world record, reaching a speed of 7.7 Ghz.
Technology is improving every day...
