Intel Core Ultra 5 250KF Plus
A March 2026 mid-cycle refresh of Intel's Arrow Lake-S desktop line: 6 P-cores plus 12 E-cores (18 total, no hyperthreading) boosting to 5.3GHz, on the existing LGA1851 socket. The KF variant drops the integrated graphics of the 250K Plus, is unlocked for overclocking, and carries a lower recommended price.
Pros
- 6 performance cores plus 12 efficiency cores (18 total), more E-cores than the original Core Ultra 5 245K/245KF
- Unlocked multiplier for overclocking on compatible Z890-class boards
- Supports DDR5 up to 7200 MT/s and 24 lanes of PCIe 5.0/4.0
- No integrated graphics keeps the KF variant priced below the graphics-enabled 250K Plus
- Drops into the existing LGA1851 socket used since the original Arrow Lake-S launch
Cons
- 159W maximum turbo power requires a capable cooler for sustained all-core clocks
- No integrated graphics, so a discrete GPU is mandatory for any display output
- Requires the LGA1851 socket, meaning a new motherboard for anyone still on an older Intel platform
- As a mid-cycle "Plus" refresh, it reuses the same Arrow Lake-S core microarchitecture and 3nm process as the original 2024 launch, with the generational jump limited to more E-cores and a larger cache rather than a new platform
Awaiting benchmarks
No Inno Score yet: single-core still needs a published benchmark result.
