Alright so this post might be a bit long but there are some interesting discussions about Rocket Lake from Reddit so I'll post it here. Also take it with a grain of salt.
TLDR: Intel could be gimping the Memory Frequency on every Rocket Lake CPU other than the i9.
Intel 11th Gen Core “Rocket Lake” full specifications allegedly leaked

So z590 has a new BIOS setting that allows the user to change the IMC ratio to be in Gear 1 (1:1) or Gear 2 (1:2). It's very similar to AMD's infinity fabric where if you go above 1900/2000 infinity fabric clock, the infinity fabric will change from 1:1 ratio to 1:2 which causes significant latency issues. With 10th gen, this setting didn't make any sense as all of their CPUs can do Gear 1 so why would you want to do Gear 2? Well with rocket lake... There is an interesting footnote in that leaked slide!
"11900K(F) SKUs are DDR4-3200 Gear 1. All other SKUs are DDR-3200 Gear 2. DDR4-2933 is Gear 1."
What his means is that if you were to run the RAM at 3200mhz on the i7 11700k like Anandtech did, you would see significant latency issues like they did.
Now they didn't actually test at 2933 as they wouldn't have known without the press review notes. So what this means is that if it's true, Intel will be artificially gimping every CPUs other than the i9 with lower memory frequencies. While memory doesn't affect Intel as much as AMD does, it will still be a shitty move as there are still a good amount of performance gains to be had with higher frequency ram. And people could have easily bought 3200mhz or above DDR4 ram 4-5 years ago.
