Reviews of that cpu including benchmarks.
The Core i5-12600K is the price/performance king in the Intel Alder Lake lineup. With its competitive pricing of $300, it's a clear winner against AMD's Ryzen 5 5600X and faster than even the 5800X in many applications and games. This is the gaming CPU you want.
