Core Ultra 5 245K 14-core desktop processor
The Intel Core Ultra 5 245K is a 14-core desktop CPU built on the Arrow Lake architecture using TSMC N3B 3nm process technology. It fits the LGA 1851 socket and combines six performance cores with eight efficient cores for 14 total threads. The processor supports DDR5 6400 memory across two channels up to 192 GB and includes integrated Intel Graphics with a 1.9 GHz max dynamic frequency.
Sustained multi-threaded workloads on 125W base
With a 125W thermal design power and 159W max turbo power, the chip maintains performance-core base frequency at 4.2 GHz and efficient-core base at 3.6 GHz under continuous load. The 26 MB L2 and 24 MB L3 caches help sustain throughput for compilation, rendering and encoding tasks. PCIe 5.0 and 4.0 lanes provide 24 lanes for high-bandwidth storage and accelerators.
Thermals noise and power in daily use
The 125W base power rating means typical workloads run at the rated thermal envelope without exceeding the 159W turbo limit. Integrated graphics operate at a 300 MHz base frequency, adding minimal heat during office or media use. Cooling solution is not included, so thermal performance and acoustic profile depend entirely on the chosen cooler and case airflow.

Vprašanja o tem izdelku
How much heat does the 125W base and 159W max turbo power produce during all-day loads?
The processor has a 125W base power and a 159W maximum turbo power, so sustained heavy workloads will require a cooler rated for at least that thermal output.
Which DDR5 memory speed and capacity does the Core Ultra 5 245K officially support?
It supports DDR5 6400 in dual-channel mode with a maximum capacity of 192 GB.
Can I keep my existing PCIe 4.0 graphics card and SSD with the 24 lanes of PCIe 5.0 and 4.0?
Yes, the 24 PCIe lanes operate at both 5.0 and 4.0 speeds, so current PCIe 4.0 devices will work at their rated performance.
