Core Ultra 5 245K desktop processor
The Intel Core Ultra 5 245K is a 14-core desktop CPU built on the Arrow Lake architecture for the LGA 1851 platform. Six performance cores and eight efficient cores deliver 14 threads for gaming and productivity workloads. The chip targets enthusiasts who want modern core topology without stepping up to the flagship tier. It includes integrated Intel Graphics for display output and quick-sync tasks.
14 cores with 24 MB L3 and 26 MB L2 cache
The processor combines 6 performance cores at 4.2 GHz base and 5.2 GHz max turbo with 8 efficient cores at 3.6 GHz base and 4.6 GHz max turbo. The 24 MB L3 and 26 MB L2 caches keep data close for latency-sensitive code. Dual-channel DDR5 6400 MT/s supports up to 256 GB with ECC for workstation reliability. PCIe 5.0 and 4.0 lanes total 24 for GPU and storage expansion.
125 W base power and 159 W max turbo power
Thermal design power is rated at 125 W with a maximum turbo power of 159 W under heavy loads. A cooling solution is not included so builders must pair it with a capable air or liquid cooler. Integrated graphics run at 300 MHz base and 1.9 GHz max dynamic frequency for light media tasks. Intel Gaussian & Neural Accelerator 3.5 and Thread Director handle AI and scheduling duties.

Questions sur cet article
Will my current DDR5-6400 memory run at its rated speed with the Core Ultra 5 245K?
Yes, the processor supports up to DDR5 6400 MT/s across two channels, so existing modules at that speed will operate at their rated frequency.
How can I verify the Core Ultra 5 245K is boosting to 5.2 GHz after installation?
Monitor the performance-core frequency in Task Manager or a hardware utility while running a single-threaded load; it should reach 5.2 GHz if thermal and power headroom allow.
Does the BX80768245K box include a cooler or must I buy one separately?
The processor is sold without a cooling device, so a compatible LGA 1851 cooler must be purchased separately.
