Overview
Jaykihn, a blogger known for accurate Intel information, revealed details this week about the company’s codenamed Bartlett Lake CPUs, which feature only P‑cores and use the LGA1700 socket. These chips can have up to 12 cores with a single‑thread boost of 5.90 GHz, making them attractive for gamers still on the LGA1700 platform (currently limited to eight P‑cores).
The flagship Bartlett Lake model – the Core 273PQE – offers 12 high‑performance Raptor Cove cores running at 3.40 GHz – 5.90 GHz, 36 MB of L3 cache, and an iGPU with 32 EUs. A power‑efficient variant, the Core 213PTE, runs at 1.40 GHz – 5.50 GHz.

Market Outlook
The key question surrounding the Core 200E‑series “Bartlett Lake” CPUs is whether motherboard manufacturers will add support for them on existing Intel 600/700‑series platforms, providing an upgrade path for current LGA1700 systems.
While it is doubtful that owners of flagship Core i9‑13900K or upcoming i9‑14900K (24‑core, 8P + 16E) rigs will replace their CPUs with Bartlett Lake, the chips could be compelling for users of mid‑range Core i5 “Raptor Lake” processors. Leaked performance data suggests that a 10‑core Bartlett Lake part may deliver ~26 % faster multi‑threaded performance than a 12‑core (6P + 8E) i5‑14400, potentially outperforming many 14‑core (6P + 8E) configurations in heavily threaded workloads. Pricing and availability, however, remain uncertain.
Intel officially announced the Core 200E‑series “Bartlett Lake” processors—targeted at edge, industrial, and embedded applications—during CES 2025 on January 6, 2025. Since then, the company has been largely silent, and the recent leak may indicate that Intel is moving closer to taking partner orders and beginning shipments.
