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.

This is the one place where I'm hyped for Zen 4 - for use in handhelds. I have the Steam Deck currently and the chip's low ST boost really hurts it for PS2 emulation in some cases, like Ratchet and Clank it dips below 60fps in moderately intensive scenes.

Zen 4 with the ability to hit drastically higher clocks at the same power combined with AVX-512 should make a much more competent handheld chip for emulation in general.

More specifically, Zen 4c, right?
Which leads me to ask, how good is Gracemont for emulation? And will Intel not release any CPU dies made only of little cores?

There is an Alder Lake-N. When you will see it who knows.

Supposedly it needs to be announced, but until now there are no news about it.
And considering that Raptor Lake is near, I don't be surprised if AL-N gets replaced by Raptor Lake-N. Yeah having 16 small cores could be interesting to see how it works.
 
Raptor Lake-N makes no sense because both Alder Lake and Raptor Lake uses Gracemonts as E Cores. So what would the changes between Alder Lake-N and Raptor Lake-N be? Uncore or GPU, at most.

Bear in mind Alderlake's AVX-512 implementation is 512-bit only for Integer. For FP it still gangs up 2x256 units just like Icelake. This isn't to be confused with Zen 4's implementation where it executes AVX-512 instructions in 2 cycles. They both have same throughput, but Golden Cove has half the latency for instructions.

Right. It's just that currently Gracemont pukes if you feed it an AVX512 instruction (or rather, the software pukes when it finds no AVX512 capability in Gracemont). My suggestion was just so the CPU could accurately report AVX512 without adding too much silicon area to Gracemont. If Golden Cove and Raptor Cove gang units like IceLake on fp instructions then that amounts to no particular barrier to implementing such a feature on Gracemont. It's confusing as to why Intel didn't try it.

13900KS I believe.

13900KS 6ghz incoming next year to do battle with the 7950x3d ? :innocent:

Slow news 🙂

Intel confirms plans to launch 6 GHz stock Raptor Lake CPU (Core i9-13900KS incoming?) - VideoCardz.com

Intel Raptor Lake CPU to hit 6 GHz stock, 8 GHz world record confirmed At Intel Tech Tour in Israel, the company confirmed its plans for the Raptor Lake series. Intel Raptor Lake series only exist because Meteor Lake wouldn’t be ready on time, stated an Intel VP at the event. The company also...

I find this comment and the other slide about meeting targets constantly hilarious.

"Look guys, CCG are super consistent and we almost always ship on time!"

"In other entirely unrelated news, Meteor Lake was going to be late so we needed a stop-gap"

Anyway, Intel 7 is holding Intel over really well and damn are they squeezing quite a lot out of it. Makes you wonder why they're not planning on offerring it as a foundry option though. Or using it for any tiles on MTL. Or hell, even producing GPUs on it. Rather odd.

Because performance/watt under full load is exceptionally bad compared to the competition?
 
41% improved MT perf of RPL over ADL, 15% ST, based on SPECint207


So much for the double digits gains "it can't be more than 10%".

While I think MLID is over the top with his claims lately, he was accurate in many of his Intel leaks some time ago, Raptor Lake was spot on with the performance prediction:

6ghz to 8ghz on 10nm 😏 10nm is just as legendary as 14nm in terms of clock speed records.. intel 4 will break 10ghz when its more mature 😁
Click to expand...
This. I always said 10nm (Intel 7) has the potential to be Intel's best process, even more so than 14nm. I'm glad to see this shaping up to be the case. By extension, 6.2 to 6.5Ghz overclocks on RPL on water is looking feasible. Remember that the 8Ghz ln2 overclock was reported to be likely the base oc on ln2, and that better overclocks are to be expected once retail silicon floods the market. Here's hoping.

Very impressive, what Intel has managed to achieve with Intel 7. 6GHz stock is no small feat. Raptor Lake will be excellent in the desktop market. For something that only exists because of MTL delays, it’s a very solid improvement.

For all of their woes in servers, Intel doesn’t disappoint when it comes to desktop parts...excluding Rocket Lake, at least. 😀

Yields.

I'd be impressed if it was 6 Ghz with normal boost and not TVB, even if it was outrageously priced.

The sooner they release 13900KS the sooner AMD will release zen4 with 3D cache, so full steam ahead intel 😀

Not true actually. If you want to properly compare performance / watt you need to do it at the same wattage. And when you do that, there isnt a big difference between a 12900k and a 5950x,around 10% in heavy MT workloads. And that difference is mostly due to ecores having bad efficiency, the P cores are more efficient than zen 3.
