Intel Core 200 "Bartlett Lake" is probably the most interesting processor gamers can't buy—built on the Intel 7 node and designed for Socket LGA1700, "Bartlett Lake" is a non-Hybrid, pure P-core chip, a monolithic silicon, with 12 "Raptor Cove" P-cores, and no E-core clusters. The 12-core/24-thread chip was launched earlier this month as an exclusive for the commercial and industrial PC OEM markets, as an edge AI PC processor, it is not drop-in compatible with consumer Intel Z790 chipset motherboards, or at least that was the plan.

A motherboard UEFI firmware mod by "kryptonfly" got a consumer ASUS Z790-AYW OC motherboard to POST with an Intel Core 9 273QPE "Bartlett Lake" processor. The modder used Claude AI to mod the UEFI firmware of the board without tripping safeguards that prevent the motherboard from booting with modded firmware. The 273QPE is a 12-core/24-thread pure P-core processor with 2 MB of L2 cache per core, and 36 MB of shared L3 cache. Its uncore components and iGPU are carried over from "Raptor Lake-S." The 273QPE has a base frequency of 3.30 GHz, an all-core boost frequency of 5.30 GHz, and a single-core TVB frequency of 5.90 GHz. The chip has 125 W processor base power, and 250 W maximum turbo power. You can watch kryptonfly's firmware mod video from the source link below.
