Intel "Bartlett Lake" Appears as a P/E-Core Hybrid, P-Core Only CPUs Could Soon Follow
Intel has launched its first wave of Bartlett Lake processors, introducing hybrid-core models specifically designed for embedded systems, with pure performance-core (P-core) variants scheduled to follow later. The initial release, unveiled at CES, showcases the processors through congatec's new COM-HPC modules. The flagship Core 7 251E leads the embedded lineup with 24 cores (8P + 16E) and impressive clock speeds reaching 5.6 GHz boost. Intel claims this processor outperforms the i7-14700 by 6% in single-core and 8% in multi-core benchmarks, despite maintaining a modest 65 W TDP. The series also includes the Core 5 211E with 10 cores (6P + 4E) and the Core 3 201E featuring 4 P-cores. However, the more intriguing development lies ahead.
Earlier sources indicate that Intel plans to release pure P-core variants of Bartlett Lake in Q3 2025, targeting desktop users. These processors will introduce a more traditional approach by replacing E-core clusters with additional P-cores, resulting in configurations of up to 12 P-cores in the upcoming Core 9 series. The pure P-core models will maintain compatibility with existing LGA1700 motherboards, potentially offering an attractive upgrade path for current Intel platform users. The lineup is expected to include 8-core, 10-core, and 12-core variants under the Core 5, 7, and 9 brands respectively, with TDP options ranging from 45 W to 125 W. While the current embedded models focus on specialized applications like medical imaging and edge computing, the future P-core variants seem positioned to appeal to gamers. The processors are expected to utilize Raptor Cove cores, though rumors suggest Intel might consider backporting Lion Cove architecture to the platform.

Their priority is still server, like AMD, then mobile chips & finally scraps for DIY :nutkick:
My apps are all mostly single threaded. (CAD/CAM)
A single 400 mm² die of the four-die big Sapphire Rapids processor would be a candidate... almost. It has 15 cores, DDR5 and PCIe5 controllers and everything. But Intel never mentioned that a single die can be made to work, and also the cores would be Golden Cove, not even Raptor Cove.
AMD did same kept releasing for old platform after new launched.
I think I might grab the 12 p core version myself. :)
I saw rumors like this last year, but I figured they'd changed their minds. I'd be tempted by a well priced 12 Pcore part with great clockspeeds. My 12700k is already pretty great. A bit more oomph for a lot less money than a 9800x3D would be convenient.
If you are a non gamer, yeah nothing to see here. 13/14900k will still be faster.
like a 12700k. Its multicore performance should outperform the 14900KS, when running in idle < 10 Watts.
If its a 12p core it could become to good of an cpu canabilising the arrow lake line or after, as such by 10p still coming in great with benchmarks somewhere even larger than what is released
than a 265k or even 285k would be it.
E-cores also come in clusters of 4, which roughly take the same die area as one P-core. I believe you wanted something like the Royal Core design, where there are P-cores and a couple of super big cores. This was supposed to be Beast Lake and to be marketed as Core Ultra series 4 (after Panther Lake/series 3, which would be Arrow Lake's refinement still on LGA 1851), but it was unfortunately canned last year.
I wonder now, will AMD still go with the Hybrid in the top tier desktop market or this efficiency cores will only be for laptops.
If Intel decides to get this one released for current boards, Intel is pulling all the stops. I think, that would have been brilliant. I'm not in the market for a CPU nor boards etc. but i would definitely look closer to Intel 12c core if I will be changing my rig in a year or 2. Still think AMD would win since if Intel does release it for the current boards, these CPUs would have been more appealing for those who have alder 13th 14th gen. AMD is not going to resign from the AM5 support at that time. Either way, huge disruption which would be awesome from a consumer standpoint.I think Intel is reaching our for gamers and the performance crown again. Take what was Intel's for so long before AMD took it.
Efficiency was never the issue on 13 14900. Limit them or get a locked 65 or 35w tdp model Most efficient chips out of the box, they probably still are. I know we like to clown on Intel and sure you can have your fun but some times we need to accept reality for what it is.
