Intel® Core™ Ultra 5 245K | Arrow Lake-S 14-Core AI Desktop Processor (Tray)
Engineered on the revolutionary Arrow Lake-S 3nm architecture for Socket LGA 1851, the Intel® Core™ Ultra 5 245K delivers 14 hardware execution cores (6 high-IPC Lion Cove P-cores + 8 power-efficient Skymont E-cores) boosting up to 5.2 GHz Max Turbo. Built for elite power efficiency drawing just 125W Base / 159W MTP, it integrates an on-die NPU AI engine, 50MB total cache, and native DDR5-6400 support for buttery-smooth competitive gaming and daily multitasking.
Cool, Quiet & Power-Efficient Modern Gaming
With 6 Lion Cove P-cores boosting up to 5.2 GHz, the 245K maintains rock-solid frame rates in competitive titles like CS2, Valorant, and Apex Legends while consuming up to 30% less power than 14th gen predecessors.
14-Core Productivity & Dedicated AI Acceleration
Equipped with 8 Skymont E-cores, native DDR5-6400 support, and a dedicated 13 TOPS NPU, the 245K accelerates video editing workflows, multi-app productivity, and local AI tasks without straining system resources.
Silicon Architecture & Visual Engineering
Verified packaging, cache hierarchy, and microarchitecture breakdown
Arrow Lake-S 14-Core High-Efficiency Die (Tray)
Engineered on an advanced 3nm process node featuring 6 Lion Cove Performance cores and 8 Skymont Efficient cores. Designed without Hyper-Threading to deliver exceptional IPC, cooler thermals, and outstanding energy efficiency.
Intel Foveros 3D Modular Packaging
Intel Foveros 3D packaging separates compute, graphics, SoC, and I/O into specialized tiles. This disaggregated layout optimizes thermal distribution, keeping the processor remarkably cool even during long gaming sessions.
Socket LGA 1851 Pinout & Gen5 Bandwidth
Built for LGA 1851 motherboards (B860 and Z890). Features 20 dedicated PCIe 5.0 lanes directly from the CPU (16x for graphics and 4x for Gen5 SSDs) plus 4 PCIe 4.0 lanes, ensuring zero lane sharing with peripheral devices.
Dedicated Intel AI Boost NPU & DDR5-6400 Support
Features an on-die 13 TOPS Neural Processing Unit (NPU) for efficient AI tasks, video background effects, and noise reduction. Native DDR5-6400 memory support delivers high bandwidth and low latency.
