It iscwell known that AMD are the ones who set up the launch date to coincide with Intel release date. I'm sick of the rumors these authors have put out to say Intel is the one who is doing the the same day launch is not true. AMD HAS STATED THAT THEY ARE LAUNCHING TO COINCIDE with intel.
AMD's Zen 4 announcement was jam-packed with the talk of performance gains of AMD CPUs over competing Intel Alder Lake chips. Intel is allegedly returning the favor on the same day as the AMD Zen 4 sale is set to go live by announcing the Core i9-13900K, the Core i7-13700K, and the Core i5-13600K.
