Discussion Intel Meteor, Arrow, Lunar & Panther Lakes + WCL Discussion Threads

[Tigerick]

Wildcat Lake (WCL) Specs

Intel Wildcat Lake (WCL) is upcoming mobile SoC replacing Raptor Lake-U. 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 Q1 2026.

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.

Any 18A yield discussion that doesn't include the opening of fab 52 is quite lacking.

Oh, there hasn't been an announcement or confirmation of fab52 PTL production yet? Guess that would also be on the menu for the earnings call then.

 

[Doug S]

Okay, you want to play that game? Then state a number. What's the 18A yield on either the PTL 484 or 404 die? Or would you prefer to tell us how many PTL parts Intel has shipped?

His response would be the usual "trust me, bro"

 

[DKR]

• PTL shipping expectations (example 1 million units by end of 2026)

FYI, that example number is too low. Just for comparison, Meteor Lake shipped roughly 18-19 million units in 2024 (launched in December'23).On CES 2025, they said they shipped >20 Mu of AI PCs with 1.5Mu contribution from LNL in Q4'24. Their current target is to ship 100Mu AI PC (MTL, ARL, LNL & PTL) in 2024 & 2025 combined which the management said they will be able to meet that target. I expect them to ship at least 20Mu of PTL in 2026 same as MTL (likely will be higher if they catch the Windows 11 refresh tailwind bar the memory prices headwinds).

Sorry, I mean this SKU. I can't remember the numbers

Yields may be impacting things. But I'm not sure it is a big issue. 200MHz miss around launch is not a huge concern. 288Vs were near mythical too and that wasn't Intel fab.

It’s not the frequency I’m worried abou. Intel cannot fab as many 484 dies hence the delay or OOS.

 

[Khato]

Yeah, frequency is only an issue for the top bin as usual. Same story as ARL there.

There's no question that Intel launches aren't the same as they were 10+ years ago where they had 2-3 months worth of production stockpiled before launch. Their launches are still a far cry from what we see done by their competition though where it can take months for initial laptops to be available. I'd guess PTL launch volume is somewhere around 1Mu.

 

[adroc_thurston]

Yeah, frequency is only an issue for the top bin as usual.

It's the issue for all >4.7G bins.

 

[regen1]

Their launches are still a far cry from what we see done by their competition though where it can take months for initial laptops to be available

Yeah, Strix Point had such poor availability(just a few Asus models) for quite some period after the launch(all with a mature node, btw).

May be some supply issues can happen but RAM situation(DDR5 and esp. high speed LPDDR5X) could potentially impact availability and sales more but that would affect most OEMs(and both x86 vendors) although to a varied degree.

 

[Khato]

It's the issue for all >4.7G bins.

No it isn't. If you want to claim it is, then what are the bin splits for the 368H part?

 

[adroc_thurston]

No it isn't.

yeah it is, we're about to have #fakeboost 2, revenge of 2019 all over again.

then what are the bin splits for the 368H part?

you know well enough that begging gets you *nothing* and yet you still do it. why even.

 

[gdansk]

Intel has made difficult to ship SKUs. 288V was nearly vaporware. And that wasn't a yield problem with N3B.
I really do not think we can deduce yield information from the lack of availability of top SKUs especially near launch.

 

[adroc_thurston]

I really do not think we can deduce yield information from the lack of availability of top SKUs especially near launch.

you can deduce it by not having any of the >4.7G SKUs hold the rated 1t boost.

 

[Khato]

you know well enough that begging gets you *nothing* and yet you still do it. why even.

Curious definition of begging. Here I thought you'd appreciate the opportunity to demonstrate to everyone that you have factual information. Here's another opportunity to prove you know something other than hearsay internet rumor - what process revision is Intel currently running for PTL?

Regardless, for anyone who prefers reality to delusion, bin splits are just fine for the 368H. And they'll be even better with the next minor process revision.

 

[adroc_thurston]

Regardless, for anyone who prefers reality to delusion, bin splits are just fine for the 368H.

they're so fine it never actually hits 5G.
Curious definition of 'fine' but whatever I guess.

 

[regen1]

Any 18A yield discussion that doesn't include the opening of fab 52 is quite lacking.

Initial 18A production in the Oregon research fabs did have low yields a year ago, probably under 20%. This is common for new nodes. Yields then go up. Once fab 52 started 18A production, you can't just use the Oregon fab research yields in discussions.

Intel said 18A yields were going up 7% per month. https://www.tomshardware.com/pc-com...eals-and-cutting-edge-18a-process-is-on-track The latest analyst statement was "over 60%" for 18A yield. https://www.investors.com/news/technology/intel-stock-intc-could-become-number-2-chip-foundry/

Is this the 70% to 80% that TSMC gets? No. Is over 60% abysmal or "toiletbowl-tier"? No. Would we like a detailed list of yield on every size chip on 18A? Of course, but we'll never get that type of info.

18A isn't some broken node like Intel 10nm was but that "7% per month" yield improvement comment from John Pitzer is unclear about what he is claiming that on. Is it like absolute or relative, (like 10+7= 17 or 10+0.7=10.7) ? On what die size (Is he talking about something like 750mm^2 die) ?, etc.
Tomshardware(Anton Shilov) seems to project it in absolute terms which seems iffy/sketchy.

This is very concerning Dell has removed the X7 12Xe core of the LCD XPS 14 and 16.

It now starts at $1599 for the ultra 5 4Xe core.

Is there not enough stock? I thought Panther lake was ramping well.

Upgrade break-down is interesting.
U5 325(4+0+4 and 4Xe3) to X7 358H(4+8+4+12Xe3) is charged 100$ less than 16GB 7467MT/s to 32GB 9600MT/s. Bit weird times for PC guys.

That RAM price looks reasonableat this point of time can't believe I said that
