Since we already have the first Raptor Lake leak I'm thinking it should have it's own thread.
What do we know so far?
From Anandtech's Intel Process Roadmap articles from July:

Built on Intel 7 with upgraded FinFET
10-15% PPW (performance-per-watt)
Last non-tiled consumer CPU as Meteor Lake will be tiled

I'm guessing this will be a minor update to ADL with just a few microarchitecture changes to the cores. The larger change will be the new process refinement allowing 8+16 at the top of the stack.

Will it work with current z690 motherboards? If yes then that could be a major selling point for people to move to ADL rather than wait.

There is a reason Intel doesn't claim 5.8 Ghz Max Boost you know right? If they did they would be in alot of trouble when reviewers get their hands on them...As AMD Did with the rated boost claims on the 3950X.
They can claim that, as long as they provide their own certified cooling solution with the CPU.

It's been widely reported:




Intel shouldn't play these tricks anymore. I couldn't remember how many times I saw the 5.8Ghz even 6Ghz examples 'leak' around though internet.......even before the announcement. Now they 'accidentally' tear down the camouflege by themselves. I think Intel PR was drunk this time.

I'm sorry, what? Anything below the 5950x is not a top bin. The 5800X uses more power for lower clocks. The only fair comparison would be 8 cores of a 5950X vs a 12900k with the 8 P-Cores, at equal power. No overclocking, no manual clocks, just simple power limits set to the same.

Anything outside of that will show you nothing about the efficiency of either chip.

EDIT: and in either scenario, you will want to test multithreaded applications, and total power consumption in each. That is why simply running the 12900k and 5950x at similar power limits (142W and below) will tell you far more about the efficiency of both chips.

All of this is meaningless, of course, because Rocket Lake was the competitor to Zen 3, not Alder Lake. Alder Lake launched well after Zen 3. Technically Zen 4 is the competitor to Alder Lake, however...oh boy.
Yeap, the test was done against a 5950x with 8 cores off. If you just power limit with no manual tuning zen 3 stands no chance man, the difference will be 30+%

Intel said yesterday that Raptorlake delivers 15% improvement in single threaded performance and 41% in multi-thread.

The previously announced "Keem Bay" VPU by the acquired Movidius corporation is going to be the one that'll be used with the 13th Gen Core systems in an M.2 module. In a demonstration, it reduced GPU utilization from 20% to 5% with the VPU active in an image recognition application. Meteorlake will go further and have an integrated VPU.

Do we know what they used in the ST comparison, which SKUs and in what benchmark? I tried looking for the info but found nothing. Is it 6Ghz on unreleased Raptor Lake part vs 12900K?

This CB R15 ST score amount to 5.45GHz...

Dunno, don't think his numbers are legit. I just run it at stock 5.2ghz and I scored 283. It's hard to accurately measure CBR15 cause it keeps bouncing threads around, cpuz doesn't have that problem

Curious to see screenshot showing 6 GHz on three cores. That's on air, correct?
6 ghz? Can't really make it to 6ghz, havent tried but I was already hitting 1.61 volts for 5.8 so yeah...

Yes it's on air, single tower cooler, and the temps were actually toasty at those ST workloads. Don't remember exactly but I think the core that was boosting was at around 85c

Sorry. I'm tired :) 85 degrees for 5.8 GHz is not bad.

Well it's not terrible but after 80c you kiss stability goodbye on Intel Cpu's, that's why it needs 1.61v. If i could keep it under 80c it can probably do it with 1.55v or something

That s not true, temp on short term reach 96°C in Prime 95 and 100°C after 2 minutes in Blender whose duration is about 4mn, so 80-85°C is still far from instability.

I think you don't understand what im saying. OF COURSE at stock it's stable, Intel and AMD give the CPUS enough voltage at stock to have them work in extreme conditions, like 100C, without stability issues. That's how people can actually undervolt them.
