Intel Launches "Arrow Lake Refresh": Core Ultra 5 250K Plus and Core Ultra 7 270K Plus, New Binary Optimization Tool
11 March 2026 at 17:00
Intel today announced the Core Ultra 5 250K Plus and Core Ultra 7 270K Plus desktop processors in the Socket LGA1851 package. These chips are drop-in compatible with existing Intel 800-series chipset motherboards, with some boards needing UEFI firmware updates. Both chips are based on the current "Arrow Lake" microarchitecture, and are carved out of the "Arrow Lake-S" disaggregated silicon that uses TSMC N3B (3 nm) foundry node for its Compute tile containing the CPU cores, TSMC N5 (5 nm) for its Graphics tile, and TSMC N6 (6 nm) node for its SoC and I/O tiles.
Both the Core Ultra 5 250K Plus ($199) and Core Ultra 7 270K Plus ($299) processor models are designed to push the current Core Ultra 5 245K and Core Ultra 7 265K, respectively, down from their current price-points. The two come with increased E-core counts, larger L3 caches, slightly increased P-core maximum boost frequency, and a 900 MHz faster die-to-die I/O frequency among the Compute and SoC tiles, which essentially makes these chips have "200S Boost Mode" out of the box. The new Core Ultra 5 250K Plus comes with a 6P+12E core configuration compared to the 6P+8E of the Core Ultra 5 245K. Its shared L3 cache has been enlarged to 30 MB, up from the 24 MB on the 245K. The P-core maximum boost frequency is up to 5.30 GHz from 5.20 GHz.
