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 a Comparison of The 13700HX which is a Alder Lake refresh(You could call it a rebranded 12900HX) with Gracemont Core Clusters(2.00 MiB Per Cluster) and The 13700K with Raptormont Core Clusters(4.00 MiB Per Cluster)

Your link isn't a comparison (both of them are the same 13700HX CPU). The URL shows benchmark 5871651 vs the same baseline benchmark 5871651.

Rebranding CPUs (sometimes with a slight frequency bin tweak) is common. It allows a company to lower prices ~25% in a year for the same CPU without calling it a price cut. It is a good thing.

Thanks, I must have put the wrong link, but you can see the screen shot right?

This is the correct link

What I am trying to say is.. The Only Mobile CPU Intel is releasing with Raptor Cove and Raptormont Hybrid design is The 13900HX. That's it.

Thanks for pointing that out. That's a glaring omission.

TPU should have them soon. But they are also biased.
The other reason I bring it up, is that some people will use anything, no matter how biased to make their favorite company look good. Quoting crap like that is even worse than the originator.

5900X is looking really good there. I almost got a 5950X+mobo+RAM for $650 on these forums. But then the seller pulled out coz he had some sort of fit against AMD mobos for being too expensive and sold off his 7950X+RAM and kept the 5950X :(

Those bar graphs show how impressive 12th and 13th gen are versus 10th and 11th gen. The gap between the 13900kf and 11900k is massive. Intel found their mojo.

I wouldn't disparage Rocket lake over its performance though. This is a game where a locked 60fps is all you need, and the stock 11600K handles it with very high + RT.

Plenty of sites will have the best AMD CPUs tested. This one would have done better to leave AMD out completely. It only draws criticism and detracts from the huge uplift that LGA 1700 brought. And how fierce the Raptor is; feasting on its predecessors.

This game seems to reward the presence of more cores with good mutlicore scaling. Hence why 5900X is near the top. I think there's a good chance the 7950X could be the winner here.
It should be similar to Spiderman Remastered, since it is the same teams porting it over. In which case the 13900K is the fastest CPU. They added RT shadows but that should hit all CPUs the same.

13900K is out in front by a significant margin in Spiderman which uses the exact same engine minus the RT shadows:

When RT is turned on, the CPU has to build and maintain the BVH structure, and that is CPU and bandwidth intensive apparently. The overclocked 12900K with DDR5 6400 nearly catches up with the stock 13900K with slower DDR5 5600 RAM and that is very indicative of how bandwidth plays a major role.

But this goes into what I've been saying about how when there is a high amount of ILP in a workload, RPL and ADL just pull ahead like no one's business. Usually most desktop applications lack high ILP in the code, but in certain types of workloads they are much more common. I'm not presenting this as a fact, just a theory.

Games with ray tracing love wider and deeper cores.. 512 rb is too strong
Or maybe Windows 11 2H22 doesn't like Ryzen


Ryzen does much better with Windows 10 (not tested with Zen 4, but Zen 3 results look fine)

PCGH has 13900K over 100% faster than Zen 2 with 8 Cores, at gamecpu.ru RTL is not even 40% faster.. so it would not suprise me, if Zen 4 is actually stronger in this game if both test systems would use Windows 10.
