Intel Core Ultra 5 245K Processor - High Performance CPU

Intel Core Ultra 5 245K Processor delivers high-performance computing with the latest Intel Core Ultra (Series 2) advances for desktop users and creators.

Built by Intel, the Intel Core Ultra 5 245K combines a hybrid architecture with 14 cores—6 performance cores and 8 efficient cores—to balance raw speed and background efficiency. The chip features Smart Cache of 24 MB and supports up to 256 GB of DDR5 memory across dual channels, enabling large datasets and heavy multitasking.

The processor reaches a maximum boost frequency of 5.2 GHz, with performance cores boosting to 5.2 GHz and a performance-core base of 4.2 GHz, while the efficient cores boost to 4.6 GHz from a 3.6 GHz base. These frequencies make the 245K well suited to demanding single-threaded and mixed workloads.

Connectivity and expansion are robust with up to 24 PCI Express lanes and support for PCIe 5.0 and 4.0 slots, allowing configurations such as 1x16+2x4, 2x8+2x4, or 1x8+4x4 for GPUs, NVMe storage, and high-bandwidth add-ons. The CPU uses the LGA 1851 (Socket V1) and ships in a tray package.

On the memory and platform side, the 245K supports DDR5-SDRAM with ECC, improving reliability for workstations and servers that need error correction. The processor also lists a PCG 2020A thermal solution specification to guide cooling choices for stable operation under load.

For AI and inference workloads, the integrated GPU environment supports popular frameworks including OpenVINO, Windows ML, DirectML, ONNX Runtime, and WebNN, making this CPU a practical choice for developers incorporating AI into desktop applications.

Typical use cases include content creation, 3D rendering, software development, advanced gaming with high-refresh-rate setups, and workstation-class productivity where multitasking and large-memory workloads are common. The Intel Core Ultra 5 245K is positioned for users who need both peak single-thread performance and efficient background processing.

Key selling points: high 5.2 GHz boost speed, hybrid 14-core design (6P+8E), 24 MB Smart Cache, DDR5 dual-channel with ECC, 24 PCIe lanes and PCIe 5.0 support, and broad AI framework compatibility.
