The Intel Core Ultra 5 245K is a desktop processor featuring 14 cores (6 performance + 8 efficiency cores) with a base frequency of 4.2 GHz and boost up to 5.2 GHz. Built on the Arrow Lake architecture, it delivers strong multi-threaded performance with a 24 MB Smart Cache and supports DDR5-6400 memory on the LGA1851 socket. With a base TDP of 125W and maximum turbo power of 159W, it offers improved power efficiency compared to previous generations.
This processor includes integrated Intel Graphics with 4 Xe-cores, supporting up to 4 displays via DisplayPort 2.1, HDMI 2.1, and eDP 1.4b. It features Intel AI Boost NPU with up to 13 TOPs performance and supports advanced AI frameworks including DirectML, OpenVINO, and ONNX Runtime. The 245K excels in productivity workloads and content creation, though gaming performance trails slightly behind the previous-generation 14600K in most titles. The retail boxed version includes the processor only; no cooler is included.
