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.

Ok, where are you getting 105W from?

That s my estimation when looking at the perf/power of the 12900K at different power points, if the 13900K@65W was to match the stock 12900K then it means that it would also match the 7950X@65W and that Intel s current process is as efficient, if not more, than TSMC s 5nm.

I'm referring to this one

Oh yes, that slide shows SPEC int_rate so it should be representative of an average performance jump in MT workloads (vs 12900K).

For reference, here is the aggregate MT performance that Computerbase compiled (useful as they used Eco mode on new Ryzens which you can use to compare to the slide you posted):

thats the thing, I believe now that its not an average, but just an "up to". Notice that the ST "up to" from the slide I posted is also the same number than this one

I think they must use the "up to" word because the Spec results are not published (official), or it's just lawyer talk (to be on the safe side). But I might be wrong, who knows.

So they bench the thing at 105W and then the base TDP is used as reference for comparison with the 12900K, that s very intel, indeed.

That sound rather desperation since they are saying that the 13900K@65W has same perf/watt than a 7950X@65W, wich of course you are ready to believe...

If you are a goose in the fog, yes everything is possible to believe. :mask:

Regardless of the lack of an i9 13900K in this comparison, "this is pretty inconvenient for Intel".In short, how to fit 8P+16E in 65W.

45W 8/16 R7 vs i9 8P+8E 65W.

Those two numbers are straight from SPECint, so no average with other benchmarks. So "up to" is Intel playing safe. Or Intel really couldn't find any use cases with better results like @deasd indicated and that's why the focus is on these two SPECint numbers instead on an average of many different benchmarks.

Intel Core i9-13900KS Special Edition 6GHz CPU to launch next year
But i'm pretty sure it wont be enough against Zen4 3d..
1664304053254.png
The new part, most likely called Core i9-13900KS will launch next year, and it will be limited in volume. The KS-series SKUs are pre-binned processors, offering the best power efficiency and stable operation at higher clocks. Last year, Intel launched its Core i9-12900KS model, which is the fastest SKU in Alder Lake-S series, offering 5.5 GHz with all cores out of the box.

It wouldn't have to mean Intel's process is better per se, just that all of the cores they're throwing at the problem actually work.

You(or maybe everybody here) can re-read the leak of 13900K QS 2 months ago:

View attachment 68286


this was very likely tested with unlimited power mode, its power peak at 420w for 1 second. most number are below 41% except 7z and cpuz.

There s other numbers but that s all Pugetbench or so :

7-640.ba036bb9.png



And for Exist50 about the improved process :

6-640.557d44a4.png

The problem I see is that they are comparing against the 5950x, and in those apps, the 7950x is WAY faster than the 5950x. And that CPU was out before the presentations were made. So we have no idea how it really does. We have to wait until the commercial results come in when it is released next month.

Pretty silly to criticize Intel for not addressing a product that left NDA just 24 or so hours before. Especially when AMD was a wuss and didn’t even address their own 5800x3d.

Indeed. Though nobody knows for sure when Raphael-X hits the streets. November? January? March? Complete unknown. So much waiting ugh.

Anyway it's hard to believe that Raptor Lake has to hold Intel over til Arrow Lake. It's a nice little upgrade for people that already liked Alder Lake, at least in those instances when it's actual Raptor Lake (and not just an Alder Lake refresh), but otherwise . . .

And on the Mobile/Laptop their Top 13900HK is an Alder Lake that will have to hold Dragon Range until Meteor Lake.
I'm curious about that bit. Is it rebranded Alder Lake, or Raptor Lake without the increase in L2? Not that it makes much of a difference either way, but still.
