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.

Raphael is already getting undercut by Raptor Lake at Micro Center. Seriously, who is the moron that thought 7600x @ $300 and 7700x @ $400 was a good 2022 sales strategy? I guess the supposed Intel "up to 20%" price increase is out the window. :rolleyes: View attachment 69465

In my country only 13700K is available for ~550€ so this might just be an excellent deal. Let's see in a couple of hours

It performs well I'll give it that, but the power!!!?

While Intel has put together a very competitive chip, they've also put together a chip that will guzzle power when allowed to – even more so than 12900K(S). In our testing, power consumption topped out at a absurd 335 Watts, over 100W more than the Ryzen 9 7950X. Those high frequencies and the additional E-cores don't come for free, even with Intel's v/f curve improvements reducing the cost.

People were complaining about AMD 95C temperature.

"The reason for this was simple, Zen 4 CPUs didn't suffer from thermal throttling and power consumption wasn't insane and this should really be the focus, not operating temperatures.

Illustrating this point is this comparison between the 13900K and 7950X, both using the Arctic Liquid Freezer II 120mm AIO liquid cooler. Now, you wouldn't pair either of these CPUs with a 120mm AIO, but with the 7950X you could and still receive performance that's comparable to what's been shown in this review.

Using the very best cooling, the 7950X maintains an all-core frequency of 5.1 GHz, with the 120mm AIO installed that frequency dropped by a mere 2% to 5.0 GHz. The 13900K on the other hand dropped from 5.2 GHz to 4.8 GHz, a more significant 8% decline in operating frequency, while also running 5c hotter."

Gaming IPC performance jump is 4% from the 12900K, so most of the uplift is due to higher frequencies, thermals and power consumption.

"The 13900K was just 4% faster on average, so if you were to overclock the 12900K to the same frequency as the 13900K, you'd for the most part receive a similar level of gaming performance"

Good news for gamers. 13900K is frugal with games.
Honestly, I don't know why anyone cares about power consumption in games. Who cares about 15 W differences when people are running GPUs at 300 W?
Computerbase: computerbase.de/2022-10/intel-core-i9-13900k-i7-13700-i5-13600k-test/
I like Computerbase, but their "single core" benchmark suite is so silly every time I see it. They really need to change it. Three different Cinebench versions and POV-Ray...seriously!?

Impressive gaming performance in CPU bound scenarios, though. The gap between Raptor Lake and Raphael would be even larger with tuned, fast DDR5.

The way is clear for Zen 4 3D to take 1st place as the best gaming CPU.

AT quote from SPEC testing, as expected IPC is basically neck and neck:
"Looking at the second set of SPEC2017 results (fp), the Ryzen 9 7950X is ahead of the Core i9-13900K by 16% in the 503.bwaves_r test, while the Raptor Lake chip is just under 10% better off in the 508.namd_r test. The key points to digest here is that Intel has done well to bridge the gap in single-threaded performance to Ryzen 7000 in most of the tests, and overall, it's a consistent trade-off between which test favors which mixture of architecture, frequency, and most importantly of all, IPC performance.

While we highlighted in our AMD Ryzen 9 7950X processor review, which at the time of publishing was the clear leader in single-core performance, it seems as though Intel's Raptor Lake is biting at the heels of the new Zen 4-core. In some instances, it's actually ahead, but stiff competition from elsewhere is always good as competition creates innovation.

With Raptor Lake being more of a transitional and enhanced core design that Intel's worked with before (Alder Lake), it remains to be seen what the future of 2023 holds for Intel's advancement in IPC and single-threaded performance. Right now, however SPEC paints a picture where it's pretty much neck and neck between Raptor Cove and Zen 4."
