Intel’s next desktop refresh is taking shape, and early leaks point to meaningful upgrades for the Core Ultra 200S Plus “Arrow Lake Refresh” lineup. Headlined by the Core Ultra 9 290K Plus and Core Ultra 7 270K Plus, the series is said to push higher core counts on select SKUs and faster clock speeds on others, all while staying on the LGA 1851 platform. With a debut expected around early 2026, likely timed for CES, this refresh looks designed to keep pressure on AMD’s Zen 5-based Ryzen chips until the larger Nova Lake-S overhaul arrives with a new socket.
What’s new with Core Ultra 7 270K Plus
The standout change lands with the Core Ultra 7 270K Plus. Compared to the Core Ultra 7 265K, the new chip reportedly jumps from 20 to 24 cores in an 8P+16E configuration. It carries 36 MB of L3 cache and keeps a 5.50 GHz boost clock, paired with a 3.70 GHz base clock. That extra cluster of E-cores should deliver a clear multithreaded lift over the 265K while maintaining similar peak single-core frequency.
An early test spotted the 270K Plus inside a Lenovo OEM system with 48 GB of DDR5 memory running at 7200 MT/s and a GeForce RTX 5090D. In Geekbench 6, it posted 3205 points in single-core and 22,206 points in multi-core—numbers roughly on par with today’s Core Ultra 9 285K in that benchmark. As always, pre-release results can vary based on firmware, thermals, and power limits, but it’s an encouraging early look.
What to expect from Core Ultra 9 290K Plus
At the top of the stack, the Core Ultra 9 290K Plus is expected to keep the familiar 24-core, 24-thread (8P+16E) layout while dialing up boost frequencies and possibly TDP. Unless Intel introduces a new desktop die for Arrow Lake-S, core topology should remain unchanged, with performance gains coming from higher clocks and tuning. Expect incremental uplift targeted at both gaming and heavy productivity.
Platform and features
The Core Ultra 200S Plus family remains on the LGA 1851 socket with platform-level optimizations, including the so-called 200S Plus Boost. The goal is straightforward: squeeze more performance out of Arrow Lake desktop silicon as motherboard partners continue supporting 800-series boards. Looking ahead, Nova Lake-S is tipped as the real generational leap, moving to a new LGA 1954 socket and a redesigned desktop architecture.
How credible is this leak?
Based on the available evidence and the level of detail, this sits between Plausible and Probable. Intel has already acknowledged an Arrow Lake Refresh on the roadmap, while specific Plus-model configurations and early benchmark figures are still subject to change before retail launch.
Specs and context at a glance
Rumored Arrow Lake Refresh (Core Ultra 200S Plus):
– Core Ultra 9 290K Plus: 24 cores / 24 threads (8P+16E), higher expected clocks, possibly higher TDP; L3 cache at 36 MB, L2 at 40 MB (as with current 24-core dies).
– Core Ultra 7 270K Plus: 24 cores / 24 threads (8P+16E), 36 MB L3, 3.70 GHz base, 5.50 GHz boost; early Geekbench 6: 3205 single-core, 22,206 multi-core.
– Core Ultra 5 250K Plus: details not yet disclosed.
Why it matters
If these details hold, the Core Ultra 7 tier becomes far more compelling for builders who want strong multithreaded performance without stepping up to a Core Ultra 9. Higher clocks on the flagship 290K Plus should also help Intel in lightly threaded tasks and high-refresh gaming. With drop-in support for existing LGA 1851 boards, the Arrow Lake Refresh could be a practical upgrade path while the industry waits for the next-socket Nova Lake-S transition.
Launch outlook
Expect more engineering samples and benchmark sightings as we move closer to early 2026. Announcements are likely around the CES window, with availability to follow. As always, final silicon, BIOS updates, and pricing will determine how these chips stack up in real-world builds.
