Intel Core Ultra 5 processor 250KF Plus

18C/18T · 5.3 GHz · 125 W

The graphics-less "F" variant of the Core Ultra 5 250K Plus, from Intel's Arrow Lake refresh for the LGA 1851 platform. It keeps the unlocked multiplier and the same core layout but disables the integrated GPU, so a discrete graphics card is required.
