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.

Intel's "official" slides for Raptor Lake, courtesy Igor's Lab.

In case anyone is wondering if that’s all for today: No! At 2 p.m. sharp, there will be a product launch with two test samples, one of which is a hot candidate for an absolute top spot in its crawl group and the other of which at least doesn’t send cold shivers down your spine. But you’ll have to come back again, but you like to do that, I know you do.
Not quite sure i understand what he is saying, but i think igors will preview 7950x vs 13900k later today (?)

With Zen3 i dont actually think it was the asynced fclk:mclk that was the problem contrary to people beliefs.. It was rather that the uclk (memory controller) dropped to half the memory speed when doing so..
On Zen4 we can run mclk and uclk synced (1:1) even if are unsycned with fclk, hence the auto:1:1* setting is recommended
* = fclk:mclk:uclk
View attachment 67244
There's another issue in that usually people tested if higher FCLKs were better by just adding 33-133MHz to FCLK and testing.

Like a I said earlier, it sounds like the optimal memory configuration is always going to be whenever you can have a neat ratio like 1:1:1, 2:1:1, 3:2:2 etc.

You know, the 13600K does have a lower stock boost than the 7600X. And the 13700K and 13900K only have the same boost as the 7700X and 7950X when using Turbo Boost Max, which Intel doesn't guarantee that all cores can actually hit that at stock.

12600K scores 1858.
13600K only 1914? It is very small difference. It is even lower than change from 4900 to 5100 MHz boost would suggest with the same IPC (1933).

Can 13600K be just renamed Alder lake chip?

Word on the street is Intel plans to use old ADL stock for the low-end RPL SKUs (non-K i5s and lower).

If the leaks are true, it seems the only difference between the i3-12100 and i3-13100 (for example) is +100Mhz base clock on the latter (and maybe higher boost). In other words, no added value from RPL IPC improvements.

Seems pretty disingenuous.

This has been confirmed on the most recent presentation leaks
