Intel Arrow Lake desktop refresh may include three ‘Plus’ CPU models

Following a disappointing debut for Arrow Lake-S, Intel is reportedly preparing to revamp its desktop portfolio with three new “Plus” models. A recent report claims that the company is planning the Core Ultra 290K Plus, Core Ultra 270K Plus, and Core Ultra 250K Plus. These chips are expected to be the final products for the LGA 1851 socket before the company transitions to LGA 1954 for Nova Lake.

The new flagship Core Ultra 290K Plus will succeed the current Core Ultra 285K. According to VideoCardz, it features the same 8P+16E core count but with minor clock adjustments. The P-Core turbo clock speed gets a 100MHz bump to 5.6GHz, the E-Core turbo clock speed rises 200MHz to 4.8GHz, and the Thermal Velocity Boost (TVB) is now rated at 5.8GHz, up from 5.7GHz.

Things get more interesting with the Core Ultra 270K Plus, which replaces the Core Ultra 265K. This model increases the core count from 8P+12E to 8P+16E, matching the Core Ultra 9 SKUs. While it gets a 100MHz boost clock speed on the E-Cores, the other clock speed figures remain the same as its predecessor (P-Cores boost up to 5.4 GHz and TVB up to 5.5GHz).

Finally, the Core Ultra 250K Plus appears to be a minor update to the Core Ultra 245K. The configuration shifts from 6P+8E to 6P+12E, with a 100MHz increase in both P-Core and E-Core boost clocks, although the E-Core base speeds reportedly drop by 100MHz.

One reported change across all new SKUs is an updated memory controller, now claiming support for DDR5-7200, noticeably higher than the 6400MT/s spec on the initial Arrow Lake-S chips.
