Intel has officially launched its Bartlett Lake CPUs, which are P-core-only processors with up to 12 cores and maintain compatibility with the LGA 1700 socket. These chips are not for consumer retail but are designed for embedded and edge computing applications, focusing on reliability, deterministic performance, and long-term support.
The product line consists of 11 commercial SKUs based on three core designs (12, 10, and 8 cores), offered at 125W, 65W, and 45W TDPs. The P-core-only architecture aims to reduce complexity and improve performance for latency-sensitive tasks in mission-critical systems.
Key features include support for Windows LTSC, Intel TCC and TSN technologies, DDR5 memory with ECC, and PCIe 5.0 connectivity. While Intel makes performance claims compared to competitors like AMD's Ryzen embedded chips, it has not published supporting benchmarks, emphasizing that these are specialized chips not intended for consumer markets or peak gaming performance.

Intel keeps socket LGA 1700 alive with new P-core-only CPUs — 'Bartlett Lake' is official, but targets embedded applications with up to 12 cores

Intel has finally introduced its long-rumored Bartlett Lake CPUs, which use a P-core-only design with up to 12 cores and are compatible with the LGA 1700 socket used on 12th- to 14th-Gen Intel chips. Contrary to speculation, however, these aren’t value-packed chips vying to earn a spot among the best CPUs for gaming. Rather, they’re commercial chips targeting embedded and edge applications.
In total, Intel is introducing 11 new SKUs, though they’re all slight variations of three different designs. There’s a 12-, 10-, and 8-core design, with slightly different clock speeds depending on the TDP. Intel is offering the chips at 125W, 65W, and 45W. At the 65W and 45W levels, there’s an additional Core 5 SKU that shaves 200MHz off the maximum boost clock and base clock of the main Core 5 offering.
The rationale for a P-core-only design is presumably the latency-sensitive applications in embedded systems and at the edge. Intel has stuck with hybrid core architectures in its consumer releases since 12th-Gen Alder Lake CPUs, but a heterogeneous architecture introduces additional complexity with scheduling tasks on the proper threads. With only performance cores, that complexity is eliminated.

As with most embedded chips, the focus is on stability and consistency, hence the several variations at different TDPs and stiff all-core boost clocks.
The chips are built on Intel 7 (10nm class) and use the Raptor Cove microarchitecture that we saw with Raptor Lake consumer chips. Elsewhere, the chips are familiar. You get up to 16 PCIe 5 lanes from the CPU, plus an additional four PCIe 4 lanes. The PCH provides up to an additional 12 PCIe 4 lanes and 16 PCIe 3 lanes. There are also up to eight lanes of Intel’s Direct Media Interface 4 (DMI 4), which was first introduced with 600-series chipsets.
On the memory front, Intel officially supports up to 5,600 MT/s DDR5, and up to 192GB in capacity with ECC support.
For performance, Intel claims the Core 9 273PE — 12 cores and 65W TDP — offers up to 4.4x lower max PCIe latency, 2.5x more deterministic response time, and 3.8x better deterministic performance compared to the Ryzen 7 9700X, which is also available in an embedded version. Unfortunately, Intel has yet to publish the benchmarks it ran for these claims in its performance index, so it’s hard to put much weight behind them.

As for broader performance comparisons, Intel didn’t share any benchmarks. Once again, these are embedded chips highly focused on reliability and deterministic behavior, not peak performance.
Because Bartlett Lake isn’t heading to retail, Intel hasn’t released any pricing information, nor a strict release date. Those details are going to be subject to Intel’s individual deals with different companies. Intel tells Tom’s Hardware that there’s no plan for a consumer release in the future. If we ever see how Bartlett Lake performs in a consumer system, it’ll likely be through gray market channels.
In addition to Bartlett Lake, Intel highlighted its edge deployments for Core Ultra Series 3, previously known as Panther Lake. Compared to Nvidia’s Jetson AGX Orin 64GB for robotics, Intel claims up to 1.7x higher performance in image classification, 1.9x lower LLM latency, and 4.5x higher throughput for vision action models. Intel also claims savings in TCO (Total Cost of Ownership) compared to dual-systems in robotics, estimating up to $5,549 in savings with a single Panther Lake SoC compared to discrete accelerators like the Jetson AGX Orin and Jetson Thor.

It’s not like you can just order these as an upgrade for your pc, but at least the platform is on life support instead of dead and buried.ezst036 said:Wait.
Intel extended a socket past "tick" "tock"?
That's awesome! -

They're using Raptor Cove cores. So, you can think of it like a variant of Raptor Lake that just replaces the 4 quad-core E clusters with 4 P-cores.ezst036 said:Intel extended a socket past "tick" "tock"?

The main issue for gamers & other home users is that most LGA 1700 boards probably won't get BIOS updates to support these CPU models, since they're being produced exclusively for the embedded computing market. So, even if you can get your hands on one of these CPUs, you'd probably have to use an industrial motherboard that would lack good support for memory OC.
I do half-expect some boutique workstation vendors to introduce products based on them, at some point. And I'm sure gaming benchmarks on the industrial motherboards that support them will show up on Youtube, before long.
It would've been cool if the 10-core and 12-core models supported AVX-512. But, I think we'd have heard about it by now, if that were going to happen. Intel has not enabled AVX-512 on any of the P-core Xeon E models that shipped thus far. -

Guaranteed 10-year availability means LGA1700 will be supported for another 10 years! Intel does designate some of their platforms as having long-term availability. Skylake was one of those.VizzieTheViz said:at least the platform is on life support instead of dead and buried.
