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.

Halo is N4P + tech from 2022/2023 (by 90%, the rest is LP, unified memory etc)

And what's your point? Intel in 2019 vs Zen 3: "Intel has an outdated core from 2015 with 14nm process versus AMD's 2019 core and 7nm process". Were you defending Bulldozer in 2010?

AMD chose not to implement the latest tech in their consumer lineup.

Battery life might be pretty good on Panther Lake. That's about it. Intel shouldn't be charging THAT MUCH just for some extra battery life though.

They are not though. Pantherlake is only 30 Euros(1770) versus more than AMD's Gorgon Point(1740). If Pantherlake goes up in price compared to predecessor, so does AMD's Gorgon Point over Strix Point.

@Hulk Integer differences can't be explained by memory system differences. It's mostly uarch. SpecFP at some point is basically a memory benchmark. Also Geekerwan shows different results for E vs LPE.

It's because Zen 5C is clocked lower, and ipc generally decreases as clock speed increases, esp if u are memory bound.

Ding Ding Ding! Likely in that review they just took the score and divided by the GHz numbers. In Geekerwan's review, it looks like they actually took the liberty of lowering the P core clocks.

 

[DavidC1]

The 4 Xe core version doing that well reminds me when they introed Celeron D based on the Prescott core and that chip beat the Northwood based Celeron by 25%+. The uarch gains are having oversized gains in lower end where it's artificially segmented, thus crippled. It only has 4MB cache, meaning it's uarch doing all the work.

Also, this is actually proof that it can't be memory bandwidth bound. Actually there's two proofs. One is that with 1.5x compute it gets 1.7-1.8x gains. And the other is the 4 Xe core version with only 4MB cache is doing this well.

Wildcatlake's 2 Xe can probably beat 96 EU in Iris Xe of pre-Meteorlake processors. That means ~4x faster than predecessor, allowing low setting gaming for modern titles.

One big difference among many:

In 2019, Intel didn't have any better tech to implement 😉 they waited for Alderlake which saved them.

AMD does have plenty: Vcache, RDNA4... isn't 2nm Zen6 also almost ready?

It makes no difference. It's all a black box. None of what we argue here makes an ounce of difference. AMD chose not to implement them. Right now Intel is the more consumer friendly vendor. They actually talked decently about PCs, versus AIMD and NVAIDIA.

It seems you always need to feed people a slice of humble pie once in a while at least.

Looking back the ST IPC equivalence of new/old cpu's is astounding.
Cinebench accelerators/E core spam used to be our top dog Skylake
Then the spam morphed into Golden/Raptor Cove!
Are they still spam I wonder?

Skylake~Gracemont~Zen 3
Raptor/Golden Cove~Skymont~Zen 4
Lion Cove~Zen 5

 

[Tachyonism]

MSI Prestige with Panther Lake 385h is $1300.

Do you mean the X7 358H instead?

I wouldn't count Multiple Cores with Int/FP of Golden Cove Spam cores.

Skylake~Gracemont~Zen 3
Raptor/Golden Cove~Skymont~Zen 4
Lion Cove~Zen 5

Zen 3 is a decent bit better than Skylake gracemont it's in the same class as sunny cove iirc

I did, my bad.

I don't think they are spam either. But some in here do.

For ST, Gracemont and Skylake are pretty even, but not core-for-core.

It seems Gracemont has the capability to do it, but in actual implementations held back by the shared L2 cache and generally slower uncore.

But Skymont shows that it was close enough that you can substitute instead of the P core in even gaming scenarios. Remember the Arrowlake test where 1+16 is faster than 8+16? Or how in Pantherlake they are prioritizing E instead of P?

Jim Keller said Skymont was made to directly compete with Zen 5. With Gracemont it was architecturally a slower core than Zen 4C. It no longer is the case.

 

[DrMrLordX]

Wasn’t that intended/expected and 18AP and 14A will be for higher clocking CPUs?

Diamond Rapids-SP was supposed to be 18a. Diamond Rapids-AP may wind up being on 18AP.

Was there time and effort for 18a that can’t be used for upcoming nodes and products?

Sorry, but what?

They are not though. Pantherlake is only 30 Euros(1770) versus more than AMD's Gorgon Point(1740).

Where are the sub-$1000 Pantherlakes? This is supposed to be a low-power SoC that doesn't even operate above 25W. It's like Lunar Lake all over again. Also how is Gorgon Point relevant when Pantherlake is competing with the now-quite-old Strix Point?
