Intel Core Ultra 7 265KF Desktop Processor

The Intel Core Ultra 7 265KF represents the latest Arrow Lake architecture, delivering 20 cores and 20 threads in the new LGA 1851 socket. This processor combines 8 Performance-cores with 12 Efficient-cores, reaching boost frequencies up to 5.5GHz for demanding gaming and productivity workloads.

Arrow Lake Architecture Performance

Built on Intel's Core Ultra Series 2 platform, the 265KF features a 125W base power design with 250W maximum turbo capability. The Performance-cores operate from 3.9GHz base to 5.4GHz boost, while Efficient-cores run from 3.3GHz to 4.6GHz. This hybrid design delivers responsive gaming performance alongside efficient multi-tasking capabilities.

AI Acceleration and NPU Integration

The dedicated Neural Processing Unit provides 36 TOPS of AI performance, handling tasks like background removal, audio optimization, and auto-framing independently from the CPU and GPU. This NPU integration prepares the system for AI-enhanced applications while maintaining smooth gaming and streaming performance.

Memory and Connectivity

Supporting up to DDR5-6400 MT/s memory with 89.6GB/s bandwidth across dual channels, the 265KF handles up to 192GB total system memory with ECC support. The platform includes native Thunderbolt 4 and USB 4.0 compatibility, WiFi 7 readiness, and increased PCIe 5.0 lanes for high-speed storage and graphics cards.

Cache and Thermal Specifications

The processor features 30MB Intel Smart Cache plus 36MB total L2 cache, optimizing data access across all cores. The KF designation indicates no integrated graphics, requiring a discrete GPU for display output. No cooling solution is included, allowing builders to select appropriate thermal solutions for their specific use case.
