Expert Features

  • 18-Core Hybrid Firepower : Combines 6 Performance-cores and 12 Efficient-cores for high-FPS gaming, streaming, multitasking, and creator workloads without turning your desktop into a loading-screen simulator.
  • Up To 5.3GHz Turbo Speed : Performance-cores boost up to 5.3GHz, delivering sharp responsiveness when games, applications, and background tasks demand instant muscle.
  • Unlocked Performance Tuning : The enthusiast-focused KF design supports processor tuning on compatible Intel Z-series motherboards, giving experienced builders extra room to push performance.
  • LGA1851 Platform Compatibility : Built for compatible Intel 800 Series chipset-based motherboards using the LGA1851 socket; it is not compatible with older LGA1700 motherboards.
  • DDR5-Only Memory Support : Supports up to 256GB of DDR5 memory across two channels, with officially listed speeds up to DDR5-7200 MT/s. DDR4 memory is not compatible.
  • Intel XMP Support : Compatible memory and motherboard combinations can use Intel Extreme Memory Profile settings for simplified one-click DDR5 performance tuning.
  • PCIe 5.0 And 4.0 Connectivity : Provides up to 24 PCIe lanes with flexible PCIe 5.0/4.0 configurations for modern graphics cards, high-speed NVMe storage, and enthusiast-class expansion.
  • 30MB Smart Cache Plus 30MB L2 : A generous cache arrangement helps keep frequently used data closer to the cores for faster gaming and productivity response.
  • Dedicated Intel AI Boost NPU : Integrated AI acceleration delivers up to 13 INT8 TOPS for supported background effects and AI workloads without dumping every task onto the CPU cores.
  • 22 TOPS Overall AI Performance : Combines available processing engines for up to 22 INT8 peak TOPS across supported AI software frameworks.
  • No Integrated Graphics : The KF model has zero Xe-cores, no graphics output, and no Intel Quick Sync Video. A compatible dedicated graphics card is strictly required.
  • 125W Performance-Class Design : Rated at 125W processor base power with up to 159W maximum turbo power; pair it with a capable LGA1851 cooling solution and quality motherboard power delivery.
  • Advanced Scheduling Technologies : Intel Thread Director, Speed Shift, Turbo Boost 2.0, and Enhanced SpeedStep intelligently balance responsiveness, efficiency, and background workloads.
  • Modern Security And Virtualization : Includes Intel VT-x, VT-d, EPT, Secure Key, AES-NI, Boot Guard, OS Guard, Trusted Execution Technology, and Control-Flow Enforcement Technology.
