Yet another reason for switching to AMD. 4 Pcores ? Really?

 

[Amdlova]

Intel is F.. they have fear from arm (Apple) invest tons of money on e-cores they need to launch it to try grab something. If the e-core can provide 80% of a p-core maybe they have something on the hands...

 

[rluker5]

16 Raptor Cove+ cores doesn't sound too bad for mobile.
Even with 18A that will be tough to keep the power consumption reasonable. Limiting the larger, more power hungry cores on mobile sounds like a good idea.
You have to remember that these e cores are faster than Zen 4, even if they are slower than the Panther Lake p cores.

Would you provide a link to the test results

If that was the case they would make a full processor out of that. These won't be close to Zen 4. Probably not even close to Zen 3.

They're going to score low on Cinebench and Geekbench so they're going to be trash since that's all that matters in 2024.

Performance wise I will wait for the reviews, but power handling and stability will be utmost important for a lot of ppl

Per leaks, Panther Lake will be for mobile, probably the successor to Lunar Lake. Nova Lake will be for desktop and mobile, replacing Arrow Lake. In between is Arrow Lake Refresh.

Intel's Panther Lake-U/H processors are designed with a multi-die architecture. They will include three active dies: one for compute tasks, one for graphics, and a Platform Connectivity Hub (PCD). Additionally, there will be two passive dies that provide structural support to enhance rigidity.

It would be a baller move to have a high-end SKU where these "filler" dies get replaced with SRAM dies, for extra L3 or L4 cache.

these e cores are faster than Zen 4,

How exactly, do you mean!?

The E-cores got too fat, and now they only have enough silicon budget left for 4 P-cores.
: D

I'm half joking, though. I think this won't be their high-end mobile part. However, it does look like the Alder/Raptor/Meteor Lake era of mainstream mobile CPUs with 6 P-cores is at an end.

What I don't get is why go to 4x LP E-cores? Are there really so many cases where you need more than 2 of them, but not more than 4?

 

[bit_user]

When Intel announced Lunar Lake, they said the Skymont E-cores have about the same IPC as Raptor Cove. Raptor Cove has better IPC than Zen 4. So, depending on how fast you think they'll clock, the 8x E-cores of Panther Lake could be slightly faster than 8x Zen 4 cores in one of their mobile APUs, if not a desktop part like the 7700X.

It's a somewhat flawed comparison, since it doesn't take into account SMT. It's also quite an extrapolation, so I'll wait for performance data on launched product.

Yeah, that was kinda my point. It's not really a known quantity, and as such comparisons don't hold up. Having hard data to explain why this may or may not be true makes it easier for everyone to understand.

Starting with Meteor, Intel had bifurcated the mobile segment into two parts, premium thin&light, and everything else. MTL's distinguishing factors are superior iGPU and better power efficiency.

That continued with Lunar, which alone has Xe2 cores out of all Intel parts for this gen, along with improved power efficiency. LNL's emphasis on efficiency does come at the expense of reducing its range on applicable laptops, which I think will cause some loss of marketshare to Ryzen 300.

Perhaps that can't be avoided, as Intel also had to worry about ARM chips making inroads with its better power efficiency--it'll be interesting to see how LNL compares to ARM on this front--and had to make efficiency the main goal. Moreover, since LNL relies mostly on TSMC silicon, perhaps it was an intentional decision to limit its target market to reduce cost.

We can reasonably say that Intel will continue the above strategy, and Panther (PTL) will again be a premium thin&light part, focusing on graphics and efficiency, and replacing LNL. But if PTL's higher core count and power limits in the rumor prove true, then PTL will have a substantially wider range than LNL, and will appear in more laptop segments to better compete against Ryzen.

Looking forward to LNL's announcement tomorrow.

I guess it would be mean of me to point out that the Ryzen AI 9 SKUs only have 4 P-cores huh?

I guess it'd depend on what they're being used for, but technically the LNL E-cores are LPE so if it's similar to that where the primary difference is being disconnected from the ring for power purposes it could make sense. If they're like the MTL implementation then yeah I'd have to agree completely that it would be weird.

LoL, I swear to god the world has turned into a bunch of grifters from game devs to the titans of chip manufacturing well Intel is losing money hand over fist now they are turning into AMD pre Dr. Lisa Su. Anyone trying to claim these E-cores are faster than Zen4 are either a TROLL or ignorant as can be. Intel is going backwards these are straight FACTS at this point. AMD has yet to launch its x3d zen5 chips and zen5 is way more efficient than zen4 while zen4 is way more efficient than Intel 13th and 14th gen and MOST likely 15th gen. Zen6 is where it changes even more dramatically for AMD as they go to 16core CCD and 32core ccx for desktop users. While on the server side is going to have up to 32core on a single CCD tell me how InFELL is going to catch up at this rate lol. Dr. Lisa Su called it saying thanks for the last 50 years but we got the next 50. mic drop...

What she has done with AMD is nothing short of remarkable. Give that woman a raise. I've ran Intel processors since 1997 but when it came time for this new build AMD was the obvious choice.

 

[rluker5]

I can give you a hint of what to expect.
They will be power limited.
More p cores means more power throttling. Not much of a point in a mobile chip.

 

[BFretts]

Hello experts, A question about x86 multicores these days. It used to be that if one core suffered an uncorrectable machine check such an SEU, there were so many opcodes in flight, and cache entanglements it was impossible to restart or resume a core without rebooting the whole processor. Is this still the case now that core counts are on the rise?

Intel Lunar Lake compute tiles are built buy TSMC just like AMD. There won't be any competitive advantage node wise for either company. If Intel's fabs fail, you will all get your fanboy products built in the same factory for the foreseeable future . Call it a Toyota or BMW, it will be pretty much the same thing. AMD rode TSMC to success, and Intel's fab issues have held them back. StRaIgHt fActS, mIC dRoP!

Starting with Meteor, Intel had bifurcated the mobile segment into two parts, premium thin&light, and everything else. MTL's distinguishing factors are superior iGPU and better power efficiency.

Starting with? They've had a die focused on the premium thin & light market + big iGPU for ages. The "GT3" iGPU goes back at least as far as Haswell U-series and R-series SoCs:

https://www.anandtech.com/show/6926/intel-iris-iris-pro-graphics-haswell-gt3gt3e-gets-a-brand
​

You can see the entire history of big iGPUs, here:

https://en.wikipedia.org/wiki/List_of_Intel_graphics_processing_units
​

There are plenty of GT3 models, a couple GT3e (with embedded DRAM) and even some GT4's.

From this, you can't exactly tell which laptop generations had a separate die for the mainstream vs. the high-end iGPU segment, but I'm sure some of them did. Certainly, Alder Lake had that with the 2P+8E die for the low-end (mostly U-series) models and the 6P+8E die for the P-series.

LNL's emphasis on efficiency does come at the expense of reducing its range on applicable laptops,
...
Moreover, since LNL relies mostly on TSMC silicon, perhaps it was an intentional decision to limit its target market to reduce cost.

I agree with the second take - it's about controlling costs.

Perhaps that can't be avoided, as Intel also had to worry about ARM chips making inroads with its better power efficiency--it'll be interesting to see how LNL compares to ARM on this front--and had to make efficiency the main goal.

I figured that was the rationale behind Meteor Lake, which seemed very efficiency-focused. It's not that hard for Intel to cut down on idle power. What's especially difficult for them is ST efficiency. In that case, at least they're on a better node than Snapdragon X.

We can reasonably say that Intel will continue the above strategy, and Panther (PTL) will again be a premium thin&light part, focusing on graphics and efficiency, and replacing LNL. But if PTL's higher core count and power limits in the rumor prove true, then PTL will have a substantially wider range than LNL, and will appear in more laptop segments to better compete against Ryzen.

The main question I have is how many different CPU chiplets Panther Lake will have. Is it just the 4P + 8E the article mentions, or could there be more? Maybe a 6P + 16E ?

Looking forward to LNL's announcement tomorrow.

Yeah, real world benchies on Lions Cove and Skymont will be super interesting!

Also slightly off the mark, since those aren't complemented by 8x E-cores, but rather 8x Zen 5C cores. The distinction being that the latter have virtually the same IPC as the regular Zen 5 cores and feature SMT.

 

[kjfatl]

I see a lot of complaints about CPU performance for the thing and light models and no mention of battery live. Most laptop users would give up performance for battery life. Personally, I would prefer a model with a '24 hour rated battery.
