Processor Intel Core Ultra 5 245KF 3.0 GHz 6 Cores 24 MB Cache FCLGA1851

The Processor Intel Core Ultra 5 245KF 3.0 GHz 6 Cores 24 MB Cache FCLGA1851 is a desktop-class CPU designed for modern multi-threaded workloads and AI-accelerated tasks. It operates at a base frequency of 3.0 GHz and includes a 24 MB Smart Cache. The chip uses the FCLGA1851 socket and supports dual-channel DDR5 memory with a stated maximum capacity of 192 GB. PCI Express 4.0 and 5.0 compatibility provide flexible high-speed connectivity for graphics cards and NVMe storage. Intel AI Boost and framework compatibility enable on-chip AI acceleration with up to 22 TOPs of performance, suitable for applications that leverage AI inference and acceleration. The processor does not include on-board graphics and is intended for systems with discrete GPUs or headless compute use.

Advantages

This Intel Core Ultra 5 245KF balances multi-core throughput and single-thread responsiveness with a 3.0 GHz base clock and an advertised boost frequency up to 5.2 GHz. The 24 MB Smart Cache helps reduce memory latency for frequently accessed data, while support for DDR5 dual-channel memory increases available bandwidth. PCIe 4.0/5.0 support ensures compatibility with modern expansion cards and high-speed NVMe drives. Integrated AI acceleration with Intel AI Boost provides dedicated resources for AI inference tasks, improving performance in supported frameworks. The lack of integrated graphics makes the processor suitable for systems relying on dedicated GPUs, maximizing compute resources for CPU and AI workloads.
