AVX-512 is certainly irrelevant today, but who knows in a couple years?

For Instance, Phenom-based processors couldn't start some games after 2015 anymore since those needed SSE 4.1 and/or 4.2, but those only had the AMD-exclusive 4.a. But in 2009, SSE4 was still even just barely used in HPC.

Either way, it would be funny if in a couple years some game would make use of AVX-512 and then run on Rocket lake, but not it's immediate successors...

Intel Core i9-12900K 16 Core Alder Lake CPU Benchmarked on ASUS ROG STRIX Z690-E Gaming WIFI Motherboard, Faster Than Core i9-11900K

https://wccftech.com/intel-core-i9-12900k-16-core-desktop-cpu-benchmarked-asus-rog-strix-z690-e-gaming-wifi-motherboard-faster-than-amd-ryzen-9-5950x/

Now these are early samples but man, if this is true, Alder Lake S is gonna be a flop. The benchmark is clearly not taking advantage of the 5950x's 16 cores 32 threads because of how close it is to an 11900k. So the fact that the i9-12900k is this close means that it's in big trouble! We will see what happens when the CPU actually comes out but if this is what Intel's answer to AMD is... This ain't it chief!

We clearly need some more test samples to see the full picture, but since Alder Lake is supposed to be released in October, I doubt it will change much over what we have right now in the leaks.

So for the high end, I expect Intel to revive it's HEDT platform with Sapphire Rapids and fight both the 5950X and the Threadrippers 5960X and 5970X with that one while Alder Lake will compete with the 5900X at best.

And that's all without the boost AMD is about to give their CPUs with the infinity cache they'll be getting for their refresh...

Interesting would have been to know the TGP or TBP of Arc to see if it can keep up in that regard or run very hot.

Another funny thing is that if Zen 4 does have AVX512, all those benches that Intel was ahead in due to AVX512 support will then be reversed.

I am personally not feeling Alder Lake S anymore as there were early leaks of Rocket Lake before it launched and the performance wasn't much different post launch. Alder Lake could be a really hot mess when it comes out, maybe even worse than Zen 1. New Memory, New PCI-E, big.LITTLE scheduling and etc. I am sure there's going to be tons of Windows and BIOS updates gonna be needed to make it all viable. Meanwhile Zen 3 gets heavily discounted and Zen 3 Vcache comes out with tried and true formula with DDR4 and gen 4 while giving people more performance. And by the time AMD comes out with their own big.LITTLE, all these issues will be fixed. If Alder Lake isn't 15-20% faster than Zen 3 with their big cores, Intel is gonna be in big big trouble.

Also they do have TDP estimates in the bottom table but I'd take it with some salt.

A reason why Alder Lake doesn't have AVX-512 but Sapphire Rapids, which comes with the same CPU chiplets does, could be because the Atom cores don't support the instruction, and this could probably be problematic if a workload gets bounced from an AVX-512 core to one that doesn't support the said instruction. So this will probably get resolved on future chips by either including the instruction into their Atom chips or through an updated scheduler in Windows and Linux that can handle this problem and ensures workloads with specific instructions don't bounce to cores who can't handle those.

Alder Lake's big cores are basically Tiger Lake, and as such only on par with Zen 3. The only way it could get significantly faster is through clock speeds in excess of 5.3 Ghz on more than one core. Which is probably gonna happen more or less considering it's power draws...
