Benchmarks of Performance-core only Bartlett Lake CPU emerge, 10-core offers 26% faster multithreaded performance than 14-core i5-14400 — 12-core version launch could be imminent

The first citing of a 10 P-core Bartlett Lake sample has emerged, with benchmark numbers giving us an idea of its potential performance. "X86 is dead&back" on X shared performance numbers of the new 10-core chip, allegedly dubbed the Core 7 253PE, compared to the Core i5-14400 featuring 26% greater multi-threaded performance despite having fewer cores.

The X poster found the Bartlett Lake chip on PassMark and compared the chip's CPU mark score against the Core i5-14400 and Core i5-14500. The Core 7 253PE scored 31,802 points, the Core i5-14500 scored 31,121 points, and the Core i5-14400 scored 25,236 points. Against the i5-14500, the Bartlett Lake 253PE was 2% faster in multithreaded performance and 26% faster than the i5-14400 in the same metric. Single-core performance was worse, though, with the 14500 being 8% faster than the 253PE and the 14400 being 3% quicker.

Bartlett Lake is the codename for Intel's embedded Core 200 series processors, based on the same P-cores and E-cores as Intel's 13th and 14th Gen Raptor Lake desktop CPUs. These chips are designed for networking and edge applications, but take advantage of Intel's LGA 1700 socket, making them physically compatible with 600 and 700-series Intel motherboards. Eight Bartlett Lake CPU models exist right now, ranging from quad-core to 24-core models, all with a mixture of P-cores and E-cores, except for the quad-core models.

However, before Bartlett Lake's official launch, rumors had it that Intel was also working on alternative high-performance variants with a special 12-core P-core-only die. If this alleged 10-core chip is real, Intel is apparently looking to build a 10-core SKU of its 12-core Bartlett Lake die with two disabled P-cores sometime soon.

12 P-core only Bartlett Lake launch looks imminent

Another poster on X, Vectral555, discovered three new listings featuring the names Core 9 processor 273PTE, 273 PE, and 273 PQE. These models are reportedly the highly rumored 12-core models; the PTE variant features a 5.5GHz boost clock, 273PE a 5.7 GHz boost clock, and the PQE a 5.9Ghz boost clock. All three SKUs also boast 36MB of cache.

All three models are listed at European retailer Mouser Electronics, suggesting this chip's launch is imminent. Despite Bartlett Lake being aimed at edge and networking applications, as previously mentioned, these chips will be drop-in compatible with LGA 1700 socket motherboards, potentially making these chips viable CPU upgrades for gamers, content creators, power users, and prosumers on existing Raptor Lake chips. There are no 13th or 14th gen CPUs that feature 12 or 10 P-cores, making these chips very interesting options for niche applications that only need 10 or 12 cores.

    If you want to call gaming niche...
    Not having e-cores allows all the power, both literally and figuratively, to go to the p-cores, so higher clocks and less having game threads be mistakenly send to the e-cores.

    comparing it to the 10core 14400 seems "meh" given the fact its finally not a +++++ node & the big thing...the new one is running up to 800MHZ faster.... thats a massive 17% increase in clock speed even ignoring any actual improvement to anythign else.

    But the single score is lower on the new one, which isn't anything new, pre release scores often are running at lower than max clocks.

    Comparing 65W base TDP to 125W base TDP similar core count parts is largely going to end up only one way.

    These BTL parts aren't likely to be unlocked and in the case of the Core 9 have worse boost clocks than 14900K/KS. The all core boost does seem to be about the same, but it's hard to say if that can be sustained within power limits. There is a possibility that the ring bus might be able to clock higher, but it will have the same number of stops as RPL so this would be the only way for the latency to improve. I don't believe they have AVX512 either, but I can't be bothered to check just relying on memory so this may be wrong.

    Overall these seem well suited for what they're aimed at, but don't seem like they'd add anything to the client market. Of course it could just be Intel 7 running at capacity to blame for why client focused unlocked versions with high single/dual core boosts haven't materialized.
