**Intel’s P-Core-Only “Bartlett Lake-S” Desktop CPUs to Feature up to 12 P-Cores and Boost Clocks up to 6.0 GHz on LGA 1700 Socket**
Intel’s Bartlett Lake-S desktop CPUs first surfaced back in January 2024. Initially, these chips were expected to be a simple refresh of the existing Raptor Lake lineup. However, it was later revealed that Bartlett Lake-S processors are primarily designed for Edge and Networking solutions, featuring some unique configurations — notably P-Core-only models with up to 12 Performance (P) cores.
### Bartlett Lake-S Still Planned for LGA 1700 Launch
Although there had been limited news recently about Bartlett Lake-S, the “A0” silicon is still slated for release on the LGA 1700 platform. According to @Jaykihn0, the fastest variant in this lineup will boast 12 P-Cores with simultaneous multithreading (SMT), delivering 24 threads in total.
Currently, Intel’s Raptor Lake and upcoming Arrow Lake desktop CPUs max out at 8 P-Cores, utilizing a hybrid architecture that combines Performance (P) cores with Efficiency (E) cores. A P-Core-only design from Intel certainly stands out in this context.
### Key Specifications of the Flagship Bartlett Lake-S CPU
– **Core Count:** 12 P-Cores with SMT (24 threads)
– **TDP:** 125W
– **Base Clock:** 3.4 GHz
– **Boost Clock:** Up to 6.0 GHz on a single core, 5.5 GHz across all cores
– **Socket:** LGA 1700
– **Overclocking:** Not supported (locked design)
The boost clock speeds for Bartlett Lake-S closely mirror those of the Core i9-14900K, which also peaks at 6.0 GHz, though it trails slightly behind the 14900KS, which can hit 6.2 GHz. However, the lack of an unlocked multiplier means no overclocking capabilities for Bartlett Lake-S CPUs.
### Performance Outlook
With 12 P-Cores and SMT enabled, the Bartlett Lake-S flagship is expected to outperform the Core Ultra 9 285K “Arrow Lake-S” desktop CPU in gaming scenarios. Bartlett Lake-S is based on the Raptor Cove P-Core architecture, known for better gaming and single-threaded performance compared to Arrow Lake-S’s Lion Cove cores.
While the hybrid Arrow Lake-S architecture benefits multi-threaded workloads, Bartlett Lake-S’s pure P-Core design might provide superior speeds in tasks heavily dependent on performance cores.
### Expected Launch Timeline
Initially targeted for a Q3 2025 release, the Bartlett Lake-S launch is now anticipated in late Q4 2025. Intel enthusiasts and professionals targeting Edge and high-performance desktop solutions should stay tuned for further updates.
