Intel Core Ultra 5 250K Plus

The Intel Core Ultra 5 250K Plus is a desktop processor built on the Arrow Lake Refresh architecture. It fits the LGA 1851 socket and works with Intel 800 series chipset motherboards. The chip delivers 18 cores split into six performance cores and twelve efficient cores with 18 threads for multitasking workloads.

Suited for gaming and content creation with

This processor suits users who want high single-thread speed up to 5.3 GHz alongside multi-thread throughput for streaming or rendering. The 125 W base power and lack of a bundled cooler mean builders must plan adequate cooling. Systems needing ECC memory support up to 256 GB DDR5 7200 benefit from the dual-channel controller.

18 cores with 5.3 GHz peak turbo

The defining specification is the 18-core configuration reaching a 5.3 GHz maximum turbo frequency on performance cores. This combination of core count and peak clock determines whether the CPU matches a workload that demands both parallel throughput and burst single-thread performance.
