A 4.2GHz base across fourteen cores — the unlocked Core Ultra 5 for a mid-range gaming build.
Quick Specs
- 14 cores (6 P-cores + 8 E-cores) / 14 threads
- 4.2GHz P-core base, up to 5.2GHz turbo
- 24MB Intel Smart Cache
- 125W base power, 159W max turbo
- Intel Graphics, 4 Xe-cores; 13 TOPS NPU
An unusually high base clock
4.2GHz base is the headline — most chips in this class idle far lower and rely on turbo. Here the Performance-cores start fast and turbo to 5.2GHz, which makes for consistently responsive gaming and application performance rather than bursty. Eight efficiency cores take on background load, and Xe graphics with four cores mean the machine posts and displays without a card. The unlocked multiplier opens up tuning on a Z890 board.
Fourteen cores, fourteen threads
Core Ultra has no Hyper-Threading, so the thread count matches the core count. For gaming that's a non-issue; for heavily threaded rendering and encoding it means comparing against AMD's thread counts carefully rather than assuming parity. Power-wise it's much more reasonable than the old i9s — 159W maximum turbo, so a good tower air cooler is sufficient rather than a mandatory AIO. No cooler is included.

- 4.2GHz base and 5.2GHz turbo on six Performance-cores
