They aren't, that game test above at locked 5GHz is IPC-test - that's fine but RocketLake clock frequency is regressed compared to Cometlake. 10900K with locked 5GHz is probably slower than stock, 5GHz 11700K is overclocked to pretty much insane power levels.
The clocks have regressed by 100Mhz, that's basically nothing, if those IPC gains turn out to be real they will still be big even with 100Mhz less if someone doesn't want the additional power draw.

You have to look more than max turbo clocks. RocketLake uses way more power than Cometlake at same clock frequency so when turbo works like it normally do, extracting all clock from available cooling capacity resulting clock will be much lower for RocketLake than Cometlake. Fixed clocks are just for IPC-comparison or overclocks - for normal use and for best performance with normal cooling default turbo behavior is the right way to operate.

You can't judge that from just one motherboard applying whatever the worst settings possible for 'infinite turbo' , O/C benchmarks and reviews of many mobos and/or actual intel suggested stock settings are going to tell us if and by how much they use more power.

Yes we can, for sure more complex CPU-core will use more power at same frequency. For lowest works it won't matter as power budget allows max turbo with single thread anyway but for moderately heavy multi-thread work it's actually perf/watt which effects mostly. Simpler cores can boost to higher clock than more complex - and that complex core's IPC has to compensate for that. Exactly same happens with Zen3 vs Zen2, within TDP there are many cases where Zen2 boosts to higher clock.

Anandtech's review did use massive cooler and infinite power budget for those test - that's actually the best possible situation for Rocketlake.

Maybe you are right, but dont forget you are comparing 8 cores to 10, so until we see a lot more data, I dont think you can assume 11900k will use more power than 10900k.

It could come close. From the 11700K review on AT, the found that it drew an extra 20W over top of the 10700K. Going back to the 10900K review, they had that pulling 50W over the 10700K, so if the 11900K uses more than 30W compared to the 11700K it could actually could top the 10900K. The AVX results certainly show that Rocket Lake is capable of being fed 290W, though whether the 11900K could pull that much outside of AVX remains to be seen, though it does seem unlikely.

Last time Intel sold a chip this big to the desktop market was 2008 with X58 and Bloomfield (~263mm²), despite using these same dies for the server market.

Intel's need to keep their margins up with a chip this big explains the head scratching MSRPs I guess.


That die is too clean for a soldered chip... is.. is this thing back to using paste???

edit: had a better look at the rest of the pictures, the one with the flash right on top shows lots of scratches. That had a thorough solder TIM cleaning done.

edit2: the blue color on top throws me off. If it was soldered it'd look like the 10900k on the right after cleaning. Something's off..

Just for the record, Cap is now defending Nvidia from Hardware Unboxed latest "attack".
"See how much overhead AMD CPUs have on Assassins Creed Origins under DX11? Hypocrites!", or something like that.


But man, that chip is big.
Intel chose to go for the "hybrid solution". Why is that, when they had demonstrated MCM chips years ago? Will Intel really continue with monolithic chips for domestic consumers?

what % of that die is IGP at this point?

About... 18-20%?

Tiger Lake's is around ~40%.

Intel releases are no longer a big deal. AMD has all of the momentum now, but not enough product.

I thought the competition would awaken a sleeping giant, but instead they were caught off guard. Thought for sure they would slap back with something other than more cores, more heat and more 14nm.

NVidia and AMD sold huge amounts of stock this week.
Looks like investors can see the trends too.
