I believe it was more to do with memory bandwidth and people generally running faster ram speeds with raptor lake where as AMD users seem abit more limited on this part due to the controller? That's what i read anyway but have yet to test it myself. Waiting for 14th gen before i jump on faster memory, 7000+mhz might see a substantial boost in performance.
But they are still using fast ddr5 for the 7xxx series, and the same speed ddr5 for the 12th and 13th gen intel stuff.
There seems to be some secret sauce beyond memory speed that is giving Raptor Lake a big win here. Combination of clock speed/architecture/l2 cache maybe?
Also, they actually have a memory benchmark in that video, and it didnt make a massive amount of difference (on Raptor Lake at least). I mean, a 10% bump going from ddr4 3800 to ddr5 7200.
