CPU Processors

Intel Ultra 5 250KF Plus 4.2GHz Processor 18 Cores for Socket 1851 Box

Key features:

  • Arrow Lake architecture (Series 2)
  • 18 next-generation cores
  • Maximum frequency up to 5.3 GHz
  • Integrated NPU for AI (22 TOPS)
  • Support for DDR5 up to 7200 MT/s
See full description

  • CPU Speed

    The speed at which the processor operates in everyday use.

    During the execution of demanding applications (e.g. games), the frequency may automatically increase up to the Maximum Processor Frequency.

  • Cores

    The natural individual processing units that the processor has. The more cores a processor has, the more efficient it is in running multiple applications simultaneously. For simple use, 4 cores are sufficient, while for gaming and video processing, at least 6 are recommended.

  • Socket

    The processor socket type.

    The motherboard we choose should have the same socket in order for the processor to "fit in".

  • Maximum CPU Speed

    The maximum processor frequency is the frequency that the processor can reach when executing demanding applications that use one core. Generally, when running demanding applications (e.g. games), the frequency can automatically increase up to the Maximum Processor Frequency depending on the number of cores in use. (the fewer cores are active, the closer they can operate to the maximum frequency)

  • Unlocked

    Ability to change the processor clock settings to achieve higher operating frequency (overclocking).

  • Cache Memory

    Cache is a very fast memory that acts as an intermediary between the processor and RAM. It stores data that is frequently useful to the processor for faster access.

Description

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.

Performance & Frequencies

  • Total Cores: 18 (6 Performance-cores / 12 Efficient-cores)
  • Total Threads: 18 (Hyper-Threading not supported)
  • Max Frequency (Max Turbo): Up to 5.3 GHz
