News Intel's P-Core only Bartlett Lake chip inches closer to reality with new Linux patch

[Admin]

An Intel engineer has validated the existence of a P-core only counterpart to Bartlett Lake-S, rumored to arrive with up to 12 Raptor Cove cores.

At CES, Intel formally introduced the Bartlett Lake-S platform, which includes three CPUs configured with hybrid cores intended for NEX (Network and Edge) applications. Since last year, rumors have alleged the existence of a performance-core-only analog, wielding up to 12P cores and 24 threads.

So if I understand it correctly, P-core-only is off the menu since the real Bartlett Lake-S ended up being heterogeneous. I wonder what the telcos thought of those hybrid chips.

Huh?

Yes, at lower TDPs, Bartlett Lake does include some hybrid models that are Alder Lake or Raptor Lake rebadges. The upper-end is still P-only, and that's likely using new silicon. You can find the full list in this article:

Intel Unveils Arrow Lake-S "non-K" Desktop CPUs; Bartlett Lake-S CPU Lineup Intended For Edge Applications

Intel has unveiled its next desktop CPUs at CES 2025, now bringing in more "non-K" Arrow Lake-S SKUs & the Bartlett Lake-S lineup.

Ok, there are a lot more of them than I remembered, with some of them including the E-cores.

So my dead platform will receive new batch cpus

It won't help you, because the low-TDP models you like will just be Alder Lake & Raptor Lake rebadges.

That list is just Jaykihn's leak, not that they haven't been spot on, but Intel still hasn't officially acknowledged the P-core only parts. It would definitely have to be new silicon for anything above 8 cores.

The biggest question really is just how much they're producing. Putting them out at the consumer level is basically a giant marketing nightmare for everyone involved. I can't imagine OEMs having an interest in trying to sell them and the DIY market is tiny. I also doubt they'd be any faster than the existing SKUs at anything in the consumer space.

Silly core nonsense. What do you do when your product peaks? You create silly spin offs. p-core, z-core, d-core. Electric power logic already built in so this silly core stuff is rather mute. This core differiation only adds to complexity and reliability and more lines of code. KISS. Keep it simple.

The application software running on a hybrid CPU usually has no special-case for such hardware. Normally, it's the same code that runs on both core types. It's normally left up to the kernel to decide which threads to run where, in order to maximize efficiency or performance.

On the matter of performance, companies like hybrid CPUs because E-cores have higher performance per mm^2 (which corresponds to perf per $). So, if your software can spin up enough threads, then it's faster (or at least more cost-effective) to use a hybrid CPU.

One of the main downsides of hybrid CPUs is in realtime applications, which I guess is why they're making a P-only CPU for realtime communications. Disabling E-cores also helps on some games, which you can think of as a kind of realtime application.

I hope it will work with DDR4 memory, my motherboard is B760 but has DDR4.

I wouldn't turn it down. Also if they do an Arrow Lake refresh, they might get me for one more go. Intel to Intel board swaps tend to go pretty well for me.

I think the chance of a LGA1700 CPU not supporting DDR4 is very small.
