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.

I know, but can you game with it below 10W? In those few games which Notebookcheck tested it use significant more power to game compare to LNL.

M5 offers around the same perf in CB2077 as Lunar in 1080P Ultra testing and the power consumption at the wall is the same or a bit lower than Lunar(depends on the laptop model)

not sure where you got significantly more power hungry from.

No guarantee unified core will be all that great either tbh. Esp in perf, even if we see a large uplift for Intel in perf/mm2 and perf/watt.

It will be cause actual competent people are leading this time I trust Stephen Robinson cause they made a core worth giving a damm with better branch prediction than

I don't think skymont is the best core in it's area class either. And perf/area is by far Skymont's best attribute.

Tbh it is if given proper cache not cache starved it's like 1.1mm2 Core+L1 don't forget that on N3B it clocks like 4.6Ghz easily and on refresh it's going at 4.8 GHz

Link please.

N3 is N3B here

Different laptop shows different results, some LNL laptop use as low as 27W while giving almost same perfomance as Macbook pro m5,

Thinkpad T14 gen 6

For comparison Macbook M5 use 43W same game. Apart from that lenovo there are number of laptops which use 30ish watts play that game at ultra settings.

Am not sure what cause that difference but my guess is scheduler, you get less power consumption by using Skymont over LC.

Ahh that’s using the Thinkpads internal screen which is 1200P and LED which is less power consumption than the 120hz mini-led





If we check with the external monitor it’s the same

Keep in mind that Cyberpunk 2.2 used in Notebookcheck's benchmark is not using the Apple Silicon native version. Cyberpunk only became Apple native in 2.3.

I was mistaken. Thanks.

That doesn't make sense, even if display is efficient it shouldnt use more power with external display unless scheduler detect external display and assume it's on table with adapter connected hence it run at full power.

There are plenty of other LNL design which use less than 40W while using external display.

yep in which case fps is lower. to maintain a near 30fps in fhd ultra, LNL must use around 40watts when using an external monitor

I don't think the E-cores rn are all that great in comparison to ARM stuff either.

It's not gonna be uncore/cache starved in comparisons to mobile CPUs.
The mediatek 9400 X4 looks like an outright better core in the same area class. It might be close in perf and area but should get dog walked in power.

 

[511]

Yup nope it is it might not be better than the Cortex X series but it is damm good vs A720/A725 FWIW it's 4MB L2+8MB SLC vs 512KL2+16MB L3 and that is it's area class

It's not gonna be uncore/cache starved in comparisons to mobile CPUs.

caches have to be fast not as poor and botched as ARL's L3 85Cycles is very bad and on mobile i think it's even worse than that
