Intel Core Ultra 5 250K Plus
Intel's mid-range Arrow Lake Refresh chip for LGA1851: 18 cores (6P+12E) at up to 5.3 GHz for $219, launched alongside the Core Ultra 7 270K Plus as part of Intel's Core Ultra 200S Plus refresh.
Pros
- 18 cores (6 P-cores, 12 E-cores), four more E-cores than the Core Ultra 5 245K it replaces
- 60 MB combined cache (30 MB L2 + 30 MB L3) and native DDR5-7200 memory support
- Unlocked multiplier for overclocking on Z890 motherboards
- 159 W maximum turbo power is easier to cool than the pricier 270K Plus's 250 W ceiling
- In review testing, praised for exceptional multi-core productivity value at its price point, with the reviewer finding no rival that matches its multi-core performance per dollar
Cons
- No cooler included in the box
- Requires an LGA1851 motherboard; no backward compatibility with LGA1700 boards
- 18 cores with no Hyper-Threading trail Intel's own higher-tier 270K Plus and 285K in heavily multi-threaded workloads
- Single-core gains over the previous Core Ultra 5 245K are modest
Very good
