Intel Core Ultra 5 245K - Arrow Lake Desktop Processor

The Intel Core Ultra 5 245K represents the latest Arrow Lake architecture, delivering advanced hybrid performance for gaming, content creation, and AI workloads. Built on the LGA 1851 socket platform, this processor combines 6 Performance-cores with 8 Efficient-cores for a total of 14 cores and 14 threads.

Core Performance Architecture

The 245K features Performance-cores operating at 4.2GHz base frequency with turbo speeds reaching 5.2GHz, while the Efficient-cores run from 3.6GHz base up to 4.6GHz turbo. This hybrid design optimizes workload distribution, directing demanding gaming and creative tasks to P-cores while background processes utilize E-cores. The processor includes 24MB Intel Smart Cache plus 26MB L2 cache for rapid data access.

Integrated AI Acceleration

A dedicated NPU (Neural Processing Unit) delivers 36 TOPS of AI performance, handling tasks like background removal, audio optimization, and auto-framing without taxing the CPU or GPU. This offloading capability maintains smooth gaming and streaming performance while running AI-enhanced applications.

Arc Xe2 Integrated Graphics

The integrated Intel Graphics with 64 Execution Units operates from 300MHz base to 1.9GHz dynamic frequency. It supports DisplayPort 2.1 UHBR20, HDMI 2.1 FRL with 8K@60Hz output, DirectX 12, OpenGL 4.5, and OpenCL 3. Suitable for display output and light graphics workloads without discrete GPU requirements.

Memory and Connectivity

Native support for DDR5-6400 MT/s memory across two channels provides up to 89.6GB/s bandwidth, with maximum capacity of 192GB and ECC memory compatibility. The platform delivers increased PCIe 5.0 lanes for next-generation storage and graphics cards, plus native Thunderbolt 4 and USB 4.0 support. WiFi 7 and WiFi 6E readiness ensures low-latency wireless connectivity.

Power Specifications

The processor operates at 159W base power with 181W maximum turbo power, requiring adequate cooling solutions (cooler not included). This power envelope enables sustained high-frequency operation during intensive workloads while maintaining thermal efficiency.

Platform Compatibility

Requires LGA 1851 socket motherboards with 800-series chipsets. Intel Application Optimization provides ongoing performance improvements for gaming titles through software updates.
