Unfortunately no gaming tests, but we are still getting a first look at more relevant benchmarks like video encoding, CPU rendering in Blender and PC Mark. Of course, Alder Lake is dominating in the single core Geekbench 5 tests, but beyond that, performance is either on par or slightly lower compared to the competition. It all might come down to pricing, as Intel's models seem to be at least $100 cheaper than the AMD counterparts, and the i5-12600K could indeed emerge as a best buy.
