Intel Bartlett Lake-S CPU Specs: 12 P-Cores, Up to 6 GHz, No Unlocked Versions

Intel is gearing up to release its new P-Core-only “Bartlett Lake-S”Desktop CPUs, which promise to deliver impressive performance with configurations featuring up to 12 P-Cores and boost clock speeds reaching 6.0 GHz on the LGA 1700 socket.

Intel’s Upcoming Bartlett Lake-S Desktop CPUs: Enhanced Performance with 12 P-Cores & 6.0 GHz Capability

First introduced in January 2024, Intel’s Bartlett Lake-S CPUs were initially anticipated to be a mere update of the Raptor Lake series. However, they have evolved into specialized processors designed for edge computing and networking applications, showcasing some remarkable features such as configurations that include only P-Cores with a maximum count of 12.

Recent reports highlight that the “A0″silicon of Bartlett Lake-S is still targeted for release on LGA 1700 motherboards. According to insights from @Jaykihn0, the premium model in this series is expected to feature 12 P-Cores paired with simultaneous multithreading (SMT), enabling it to handle up to 24 threads. In contrast, current offerings in the Raptor Lake and Arrow Lake lines max out at 8 P-Cores in a hybrid architecture with E-Cores, making a P-Core-exclusive CPU an intriguing development for enthusiasts.

The anticipated flagship 12 P-Core model of the Intel Bartlett Lake-S will operate within a Thermal Design Power (TDP) of 125W, boasting a base clock frequency of 3.4 GHz, alongside a single-core boost clock of 6.0 GHz and a multi-core boost of 5.5 GHz. These boost frequencies are competitive, matching the Core i9-14900K’s 6.0 GHz peak but falling short of the 14900KS, which can reach up to 6.2 GHz. Notably, this CPU will be non-unlocked, meaning users will not have the option for overclocking.

With its 12 P-Cores and SMT capabilities, the Intel Bartlett Lake-S 12-Core CPU promises to enhance gaming performance compared to the Core Ultra 9 285K from the Arrow Lake series. Built on Raptor Cove P-Cores, these processors have demonstrated superior gaming performance over the Lion Cove cores featured in Arrow Lake’s architecture. However, the hybrid design of the Arrow Lake-S may provide advantages in multi-threaded tasks.

Originally slated for release in Q3 2025, the launch of the Bartlett Lake-S CPUs has been shifted to late Q4 2025. Stay tuned for further updates as the release date approaches.
