Recent leaks suggest details about Intel’s forthcoming Core Ultra 200S Plus “Arrow Lake Refresh”CPUs, including the Ultra 9 290K Plus and Ultra 7 270K Plus.

Revealing the Intel Core Ultra 200S Plus “Arrow Lake Refresh”CPUs

The Arrow Lake Refresh CPU family is set to be officially unveiled at CES 2026, with a launch anticipated in early 2026. More specifics have emerged about two key models: the Core Ultra 9 290K Plus and the Core Ultra 7 270K Plus.

Part of the Core Ultra 200S Plus series, this lineup is designed to increase core counts for some WeUs while boosting clock speeds for others. The CPUs will continue to utilize the LGA 1851 socket and introduce performance enhancements such as the 200S Plus Boost, aiming to better compete with AMD’s latest Zen 5 Ryzen processors. However, true next-gen upgrades will arrive with the Nova Lake-S platform launching next year.

Intel Core Ultra 7 270K Plus Overview

The Intel Core Ultra 7 270K Plus is a step up from the previous generation Core Ultra 7 265K. Notably, it features an enhanced core configuration with 24 cores, up from 20, organized as an 8+16 layout. This model boasts 36 MB of L3 cache, maintaining clock speeds of 3.70 GHz base and 5.50 GHz boost—mirroring its predecessor’s maximum boost clock while promising improved overall performance.

Geekbench 6.5.0 benchmark results for Lenovo model 3784 with Intel Core Ultra 7 270K Plus show 3205 single-core and 22206 multi-core scores.

Comparative Analysis: Core Ultra 7 270K Plus vs Core Ultra 7 265K

Core Count: 24 vs 20
Boost Clock: Both at 5.50 GHz
L3 Cache: 36 MB vs 30 MB

The Core Ultra 7 270K Plus achieved a single-core score of 3205 and a multi-core score of 22, 206 in the Geekbench 6 multi-core test, paralleling the performance of the flagship Core Ultra 9 285K.

Intel Core Ultra 9 290K Plus Insights

As the flagship model of the Core Ultra 200S Plus series, the Core Ultra 9 290K Plus is expected to retain its 24-core, 24-thread configuration, with higher clock speeds potentially on the horizon. While the specifics are yet to be confirmed, any sudden shifts in architecture, such as an unexpected new Arrow Lake-S die, seem unlikely.

Additionally, a Core Ultra 5 version is anticipated within this series, but details remain sparse. This lineup appears strategically designed to clear excess inventory from the 800-series motherboards before transitioning to the next-generation Nova Lake-S platform, set to feature the new LGA 1954 socket. As we near the 2026 launch, expect further leaks and confirmed details to emerge.
