Intel’s Bartlett Lake-S P-core-only desktop chips are still on track for the LGA 1700 socket, and the flagship is shaping up to be a 12-core, 24-thread part that can hit up to 6.0 GHz. First spotted in early 2024 and initially mistaken for a simple Raptor Lake refresh, Bartlett Lake-S was later identified as silicon aimed at edge and networking use cases. Now, fresh details suggest desktop-bound “A0” silicon is planned, with an emphasis on high clocks and big-core muscle.
The headline chip reportedly carries 12 performance cores with SMT/Hyper-Threading for 24 threads, a 125W TDP, a 3.4 GHz base clock, up to 6.0 GHz single-core boost, and around 5.5 GHz all-core boost. It’s a locked SKU, so don’t expect overclocking. That 6.0 GHz peak matches the Core i9-14900K’s turbo and lands just shy of the 14900KS at 6.2 GHz. What makes this lineup especially intriguing is the pure P-core design; current mainstream desktops such as Raptor Lake and Arrow Lake-S top out at eight P-cores and rely on a hybrid mix of performance and efficiency cores.
Bartlett Lake-S is based on Raptor Cove P-cores, a microarchitecture that has already proven extremely strong in latency-sensitive tasks. In gaming, where high-frequency big cores often rule, a 12-core P-core-only design could edge out hybrid rivals like the Core Ultra 9 285K from Arrow Lake-S in many titles. That said, Arrow Lake’s hybrid approach with efficiency cores can still pull ahead in heavily multi-threaded workloads that scale beyond the strengths of pure P-cores.
Key points at a glance:
– Socket: LGA 1700
– Architecture: Raptor Cove P-cores
– Top configuration: 12 P-cores with SMT/Hyper-Threading (24 threads)
– TDP: 125W for the flagship
– Clocks: 3.4 GHz base, up to 6.0 GHz single-core, about 5.5 GHz all-core
– Overclocking: Locked (no K-series equivalent)
– Positioning: High-frequency P-core-only design targeting top-tier gaming and responsive desktop performance
Beyond the flagship, the broader Bartlett Lake-S family is expected to span multiple power tiers and core counts:
– P-core-only options across 125W, 65W, and 45W classes with 12-core, 10-core, and 8-core variants
– Hybrid desktop refreshes in 65W and 45W using existing Alder/Raptor Lake dies, including configurations like 8P+16E, 6P+8E, and 6P+4E
– Entry-level hybrid options with 4P/0E and 2P/0E
Timing has reportedly shifted from an initial Q3 2025 target to a late Q4 2025 window. If you’re running an LGA 1700 platform and prefer raw P-core performance and ultra-high boost clocks without the complexity of E-cores, Bartlett Lake-S could be the most compelling late-cycle upgrade on this socket.
As with any pre-launch information, specifications and schedules can change, but the direction is clear: Intel is preparing a high-clocks, P-core-only desktop line that aims squarely at gamers and enthusiasts who demand swift single-thread performance while still packing 24-thread muscle for modern workloads.
