Intel Core Ultra 5 245K 14-Core Desktop Processor

This desktop CPU uses the Arrow Lake architecture with six performance cores and eight efficient cores for fourteen threads. It fits the LGA 1851 socket and has a 125 W base power rating. The processor suits enthusiasts and entry workstation users who need strong single-thread speed and efficient multi-tasking.

Upgrade from an older platform to LGA 1851 and

It replaces a CPU on a previous socket and moves you to DDR5 6400 MT/s memory with up to 256 GB capacity across two channels. The jump is worth it when you want the new NPU for AI workloads, Xe LPG integrated graphics, and the 3 nm process for higher performance per watt. ECC memory support adds reliability for critical workloads.

Check motherboard socket chipset cooler and power

You need a motherboard with the LGA 1851 socket and a chipset that supports Core Ultra Series 2 processors. Verify that your CPU cooler is rated for at least 125 W base power and fits the LGA 1851 mounting pattern. Confirm your power supply can deliver sufficient current for the platform and that your DDR5 modules are compatible with 6400 MT/s operation.
