Intel is apparently working on a new CPU with 12 P-Cores and sky-high clock speeds of up to 6GHz. Yes, Intel Bartlett Lake-S desktop processors are back in the rumour mill, with the latest leak regarding the clock speeds and overclocking potential of these new CPUs.
Using the same LGA1700 socket as Intel’s 14th-gen Raptor Lake CPUs, Bartlett Lake chips are said to only offer P-Cores, and no E-Cores. According to regular Intel tech leaker @jaykihn0 on X, the flagship Bartlett Lake-S model will have 12 P-Cores and a top 6GHz boost clock. Meanwhile, this flagship chip’s all-core boost clock will reportedly be 5.5GHz, with a 3.4GHz base frequency.
These specs are notable, as no desktop Intel desktop processor has had more than eight P-cores from the moment the company debuted its hybrid architectures. That even inclues halo models like the Intel Core i9 14900KS. Yes, it looks like it loses the 16 E-cores, which can come in handy for offloading background tasks and multi-tasking, but in their place, it appears to gain four extra P-cores, which could make it stronger for gaming.
That said, it’s important to keep in mind that Intel’s own documentation points to Bartlett Lake-S being targeted at edge computing rather than gaming. As such, while Intel says Bartlett Lake will use the same socket as 12th, 13th, and 14th Gen Intel CPUs, support on consumer motherboards isn’t guaranteed.
| Hybrid | P-Core Only | |
| SKU | 65W / 45W | 125W / 65W / 45W |
| Core 9 | None | 12P |
| Core 7 | 8+16 (B0) | 10P |
| Core 5 | 6+8 (B0) / 6+4 (C0) | 8P |
| Core 3 | 4+0 (H0) | None |
| Core Processor | 2+0 (H0) | None |
The leaker has also indicated that the 12 P-core model will not be unlocked, which means it won’t support overclocking through its multiplier. Limited overclocking should still be possible using the base clock, but at a great risk of instability, so not worth it. Thankfully, this shouldn’t be a concern anyway since 6GHz is already very good, exceeding even the current Core Ultra 9 285K. Lastly, @jaykihn0 corroborated the previously rumoured 125W TDP of this chip, suggesting it won’t need special cooling.
According to Intel’s official presentation, Bartlett Lake-S will support DDR5-5600 memory (and DDR4-3200 on some SKUs), along with up to 16 PCIe 5.0 lanes and 4 PCIe 4.0 lanes on the CPU, plus additional PCIe 4.0/3.0 lanes on the PCH. It also support ECC memory and come equipped with an Xe integrated GPU containing 32 execution units.
Considering all this, we wouldn’t be surprised to see the flagship Bartlett Lake-S beat its Arrow Lake-S counterpart, especially in gaming and tasks that can’t take advantage of the E cores. But as always with unreleased products, we can’t be sure until we’ve conducted our own hands-on testing. That could happen soon enough, though, as Bartlett Lake-S CPUs are expected before the end of 2025.
