Description

The Intel® Core™ Ultra 5 250KF PLUS (Series 2) belongs to the brand-new Arrow Lake processor family, designed to deliver top-tier performance in desktop systems. With an advanced 18-core hybrid architecture, support for ultra-high-speed DDR5 memory, and an integrated neural processing unit (NPU), it is the ideal foundation for gaming, content creation, and AI applications.

Note: The "KF" version does not include integrated graphics, so a dedicated graphics card is required.

  • 18-Core Hybrid Architecture: Combines 6 powerful performance cores (P-cores) for heavy workloads and gaming, with 12 energy-efficient cores (E-cores) for excellent multitasking.

  • AI Boost Technology (NPU): Features a dedicated AI processing unit (NPU) with 13 TOPS performance (22 TOPS total with the CPU), accelerating artificial intelligence applications and fully supporting Windows Studio Effects.

  • Cutting-Edge Design: Based on TSMC N3B lithography, it delivers top-tier power efficiency and lower temperatures.

  • Intel® Thread Director: An intelligent controller automatically distributes tasks to the appropriate cores, ensuring the system never slows down.
