Wildcat Lake (WCL) Preliminary Specs

Intel Wildcat Lake (WCL) is upcoming mobile SoC replacing ADL-N. WCL consists of 2 tiles: compute tile and PCD tile. It is true single die consists of CPU, GPU and NPU that is fabbed by 18-A process. Last time I checked, PCD tile is fabbed by TSMC N6 process. They are connected through UCIe, not D2D; a first from Intel. Expecting launching in Q2/Computex 2026. In case people don't remember AlderLake-N, I have created a table below to compare the detail specs of ADL-N and WCL. Just for fun, I am throwing LNL and upcoming Mediatek D9500 SoC.

As Hot Chips 34 starting this week, Intel will unveil technical information of upcoming Meteor Lake (MTL) and Arrow Lake (ARL), new generation platform after Raptor Lake. Both MTL and ARL represent new direction which Intel will move to multiple chiplets and combine as one SoC platform.

MTL also represents new compute tile that based on Intel 4 process which is based on EUV lithography, a first from Intel. Intel expects to ship MTL mobile SoC in 2023.

ARL will come after MTL so Intel should be shipping it in 2024, that is what Intel roadmap is telling us. ARL compute tile will be manufactured by Intel 20A process, a first from Intel to use GAA transistors called RibbonFET.

It will not cross 170 cause the geekbench inflation is due to the Matrix extension it will be around 165

Fair enough. Using Geekbench 5 where that additional bump due to SME isn’t utilized in the benchmark, the improvement is ~16.75%, so going by that and the correlation remains it could breach 165 maybe up to 167.

Looks like the score is improving nicely for LNL

Thats interesting. If LNL is posting such good ST scores, ARL-S might actually beat the competition in ST (and obviously MT too).

256V is the lowest tier Ultra 7 SKU, too. It only boosts to 4.8GHz (confirmed by the Geekbench results page) while 266/8V go up to 5.0. Not a massive difference but not insignificant either. (The 30W PL1 chip goes up to 5.1 but it's not really comparable.)

I wonder what the clock speed was in ST mode.

[AMDK11]

That is 0.9-1.0GHz less than the flagship ArrowLake-S.

Is there any possibility of comparison with Zen5?

An excerpt from TweakTown:

"The new Ryzen AI 9 HX 370 "Strix Point" APU scored 2010 points in Cinebench R23's single-core test and 23302 points in the multi-core test. The single-core result beats Intel's current flagship mobile CPU, the Core Ultra 9 185 "Meteor Lake" CPU (which scores 1935 points), and just 17147 in the multi-core run against 23302 from the Ryzen AI 9 HX 370.

Intel still has the lead with its desktop-class 55W version of the Core i9-14900HX, which scores 2193 points in the single-core run of Cinebench R23, and 30411 points in the multi-core run. AMD's own Ryzen 9 7945HX3D processor also beats the new Zen 5-based Ryzen AI 9 HX 370 "Strix Point" APU, but not in single core (the 7945X3D scores 1935 points in single-core) but beats them all in multi-core scores with 32782 points.

Looking at this, it appears ARL might match or beat the competition in ST.

Geekbench 6.1.0 for Windows AVX2?

 

[controlflow]

I expect LNL will be the closest thing to the Apple M series but for Windows. I really think it will make the current Snapdragon X stuff largely irrelevant since LNL will not have compatibility issues and will have a better NPU and a massively better GPU. I think it is likely that it will finally put to rest this notion that ARM ISA magically has some kind of significant low power advantage over x86. It really just comes down to core microarchitecture, system architecture and strong software/OS integration to do low power properly. LNL should be much improved in all of those areas and is probably the first real sane low power effort from the x86 camp.

Wildcat Lake is a low-cost SoC line-up that is meant to slot in products between ADL-N and MTL/ARL/PTL-U series (So, basically, budget laptops). It will feature P, E and LPE cores of unknown uArchs (Raptor/Grace? Redwood/Crest? Lion/Sky?) and also will feature a NPU based on Meteor Lake NPU (Or so was the original plan of the project).

IMO It's very likely to be an optimization/waterfall version of Meteor Lake with smaller ACM+ GPU and reduced IO/SoC (Fused tiles?).

I'm not sure if this was posted before: https://news.mynavi.jp/article/20240629-2975570/

It's a series of articles (3 parts) detailing LNL architecture. It's in JP so translator is needed (unless you know Japanese ).

Based on translate the guy is saying the 2x3 cluster on Gracemont was used for Hyperthreading. I stopped reading. When "technical" writers lack fundamental understanding of what they are writing about, it's worth less than toilet paper after being used for it's intended purpose.

@Geddagod AFAIK Sierra Forest does not have SMT.

Why do I get the feeling that this article was "generated" with AI? [Edit:] Yeah, the link about the 576 threads leads to a slide from Intel's deck... showcasing a dual socket Sierra Forest.

Spoiler

They are either complete amateurs or using LLM to generate articles, which is basically the same these days.

Afaik the 576 thread version had dual 288 cores SRF which is Insane NGL

A 17% increase in CB23 from the 14900K doesn't look good? What I'm missing here.

Stil a qs sample.. tsmc n3B doesn't look efficient yet

I think the 14900K does a little better at CB23 than that Xitter post shows. For example, from TechPowerUp:


Idk how AT’s sample scored so high either:


From Tweaktown:

 

[inf64]

I'm not sure which profile was used for 14900K but according to CPU monkey, the SKU should score 38700 pts.
For reference 7950x gets 38.6K , while unofficially the 9950X gets 43.9K pts.

nah, disregard my post, the issue is with the ST performance. Also MT is behind expectation, still a QS sample tho.
