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.

I measured lower load efficiency, I put the outcome in the disaster thread. At low load it is similarly efficient as 12600K, but at high load it is even less efficient.

BTW the IPC improvement in Cinebench seems to be slightly negative. The score improvement is just frequency driven.

I will try to find in the bios how to limit the power.

The wafer box is really nice and solid. I like it a lot... :D

Ok, I must say I did not expect 337W. Here are the results. It ran at 85°C with Arctic Liquid Freezer II 240.

EDIT: Now I got 40 774. P cores run at 5500 MHz and E cores at 4300 MHz.

Alder Lake running those frequencies with that number of cores would score about 38,900. Raptor is about 4.6% better. Either the clocks are floating around as they normally do and IPC for Raptor=Alder for this benchmark or there is a slight IPC improvement for Raptor.
Can you nail down a frequency for the ST score? At 5.7 Alder would do about 2220.

Really? Negative IPC?? Are you sure it's not just some Beta BIOS or just crappy Motherboard? Dud CPU?
It's probably a margin of error thing. The IPC is most likely within 1% so any difference can be disregarded. Not a bad frequency uplift but still much lower perf/watt than 7950X, at least in R23.

That is unlimited power. The picture showed 'Limited vykonu PL1/PL2' at 4095watts.

The question is, was that the stock motherboard setting? Based on the comments from @Kocicak , it seems like this is what the motherboard is set to out of the box. Hopefully he can confirm. If so, this is similar to what Intel/MB makers did previously where the "official" guidance was PL2 for a limited time (tau) which after it expired, power would drop to PL1 but then pretty much all the motherboards out of the box set tau to unlimited meaning you were always at PL2. This was not the "official" stock setting but it seemed Intel either didn't care, or was actually promoting this behind the scenes. Do we get a repeat here where "officially" the CPU should be limited to 250 W for sustained loads but pretty much every motherboard comes out of the box with an unlimited power setting? Maybe this is just the pre-release board BIOS behavior? Will be interesting to see how things end up with release reviews.

So 13900K around 8-9% faster than the 7950X in CB23? Intel will put a lot of pressure on the AM5 platform if these results are translated to real world performance. AMD is just to expensive to justify.

I do not play games, I do not have any discrete graphic card now. I want to get RX6600, but it is still not dropping in price for some reason.

At 335W and an AIO vs 220W air cooled 7950X, using the same air cooler as the latter it would run at 130°C...

So it's a HEDT/Workstation on a Budget? Yeah 13900K and budget would not seem to go hand to hand, but HEDT it's just too expensive at this time thanks to Intel Lagging behind.

Well it's running on an "older" node. Intel competing with a worse manufacturing process and even beating the competition (at the expense of efficiency) is good news for them. MTL-S should be a good test for Intel to see if they can regain a significant advantage over AMD again.

Seems like with good cooling and DDR5 41K, maybe 42K, should be doable.
The 40K figure is achieved with auto-OC feature in the BIOS, the P cores are running at 5.5Ghz and E cores at 4.3Ghz. The P cores might have a bit more room left but I doubt it's worth it as the chip is already consuming 330W using these settings.

I was not hitting any thermal limit during the test - maximal temperature was 85°C. I also did not tune the CPU in any way. I believe I could get higher score with this CPU if I tried to overclock it, undervolt it, etc.
Could you set the PL2 to 250W and see what the stock performance is?

For reference, this is the stock Turbo spec according to intel : https://www.intel.com/content/www/u...-36m-cache-up-to-5-80-ghz/specifications.html

The unlimited mode is analog to PBO2 on 7950X (when using a premium cooling), but no review so far (to my knowledge) has tested with PBO2 enabled.

If you tell me where it is, I looked in the BIOS and did not find it. It is 21:32 here already and I may do it tomorrow or over the weekend.

It should be called Power Limit or TDP limit, but I'm not sure to be honest. We had no BIOS leaks that show how it's called (probably depends on the motherboard maker).

R15 is more like a median result than R20/R23 when summarized together with other realworld workload. Computerbase has a good 7950X review, R23 gives Intel more advantage than any other tests.

It's quite funny that so many people blindly trust MAXON software.
