Intel i7-11700K Memory Benchmarks: Gear 1 vs. Gear 2 on 3200MHz
The Anandtech early review of the 11700K says this about the memory controller setting " For the avoidance of doubt, in our testing on every microcode to date, all of our motherboards were running at a 1:1 ratio". So, not looking good for Rocket Lake, considering the performance and UK pre-order pricing...
Also, now I'm wondering if there will be any problems running the memory controller at 1:1 at DDR 4 frequencies higher than 3200mhz...
I suppose we will need to see a proper review from Gamer Nexus, comparing the 11700K and 5600X / 5800X, to get a clearer view of how it compares.

3200mhz is where the official memory support cuts off, no gaurantee to get over 3200mhz with 1:1 with the IMC. However there are a few people who have managed to get 3733mhz 1:1 but not a single person has gone higher, the IMC absolutely refuses to let the system boot of you go over 3733mhz

Only on the UK site as the US still has both. Supply issues
Pretty sure its AMD chips with supply issues.
It's also not just the UK. They've probably dropped the Intel systems in lots of large markets because no one was buying them.

Oh really? Does this apply to the Ryzen 5000 series too?
Limit eerily similar to Zen 2/3 memory controller. And much lower than previous gen.
Except Zen 3 can now work up to 4000MHz if lucky.
Wonder how high clock 4000+MHz memory runs on Rocket Lake now. Will we have another "sweet spot 3600" case?
you can still run your memory past 3733mhz but you have to set the IMC to "gear2" in the bios or the system won't boot, that makes the IMC run at 50% of the memory speed instead of 100% - downside is gear2 adds 10ns extra memory latency.
As you say very similiar to ryzen's memory architecture, but Ryzen does it better since some can manage 4000mhz and boot with IMC at 100%. AMD also gives more options: With Ryzen you can set the exact IMC frequency you want, Rocket Lake only gives you two options, 100% of ram speed with a 3200mhz soft cap and 3733mhz hard cap or 50% of ram speed with 3200mhz soft cap and unknown hard cap

Wonder why Intel went this route, when previous memory controller would happily run up to 4500MHz without any sync/async penalties.
And while on topic of old controller, why was the official supported speed capped so low for so long? 2933 even on top of line overclocker friendly models? Which now gets bumped to 3200 with a mile of footnotes and caveats?

I think it's safe to say this isn't where Intel wants to be right now.

The architecture was designed for 10nm. Because Intel can't get their 10nm production working adequately it was backported to 14nm and it appears to have gone poorly.
They've rolled it out anyway just to be seen to be putting out something new.
Yeah I've been vaguely following their process troubles, I just wondered if they went ahead with RL knowing it wouldn't set the world on fire, but rather to shall we say 'beta test' the new desktop arch and make a few quid along the way. I only have a passing knowledge of these things though and out of the loop
If I remember correctly, in the past Intel used to use memory straps or something like that. If you go over certain (predetermined) memory speed, motherboard would set RAM/mem controller ratio and would drop mem controller speed to keep RAM stable. That was long time ago though, back in x79/x99 socket days.
JEDEC doesn't really care about 0.1% of the market. Besides, if JEDEC certifies the speed, that means that whichever 2933/3200Mhz RAM module you slot into your motherboard, it will work straight out of the bat. Everything above it is not as straight forward as we might think it is.
I have 3600Mhz "Tested on Ryzen" 8 Pack 2x16GB RAM with b-dies, Asrock x570 Taichi and 5950x. And for the love of every voltage tweak for SOC, IOD, I cannot make them run stable at their xmp settings, even with much higher RAM voltage than required on paper. AMD has to make sure that 100% of memory modules will work at their advertised speeds
They're not

Yep that USA market is tiny...
When did I say they dropped it in the USA?

'large markets', wouldn't that be one of the largest? What about Japan, China, India, Australia....
