Product overview

Announced on March 11, 2026 and available March 26, 2026, the Core Ultra 5 250K Plus is a 15th‑gen Arrow Lake desktop chip in Intel’s Core Ultra Series 2 family for LGA1851/800‑series boards. Intel lists it as launched and current.

Positioned as a mainstream, i5‑class part, it exists to offer an affordable unlocked upgrade path on the new platform. The 6P+12E (18‑thread) design, 4.2 GHz base clocks and mid‑5 GHz turbo, 30 MB cache, and 125 W base power make it well‑suited to 1080p gaming rigs and mixed‑use creator systems. It supports DDR5‑7200 and PCIe 5.0/4.0, and includes integrated graphics for display and light tasks. Notable: the K‑suffix brings an unlocked multiplier for overclocking when paired with Z‑series boards.
