Processor INTEL Core Ultra 5 250K Plus, FCLGA1851 socket, 30 TOPs NPU, 30 MB cache, Dual-channel DDR5, Tray

Desktop processor INTEL Core Ultra 5 250K Plus in tray packaging for FCLGA1851 socket. The chip integrates Intel Graphics and an AI accelerator (NPU) capable of up to 30 TOPs, supports dual-channel DDR5 memory up to 256 GB, and offers PCIe 4.0/5.0 connectivity. It is designed for modern workstations and client PCs that require hardware AI acceleration and contemporary I/O options.

Advantages

The processor combines an 18-core 64-bit CPU design with a 30 MB Smart Cache and integrated graphics, providing balanced compute and multimedia capabilities. Built-in NPU (Intel AI Boost) accelerates AI inference workloads up to 30 TOPs and is compatible with frameworks such as DirectML, OpenVINO and ONNX RT. Dual-channel DDR5 support and PCIe 4.0/5.0 ensure high memory bandwidth and fast peripheral connectivity.

Suitable for

• Workstations performing AI inference and multimedia tasks
• Client PCs requiring integrated graphics and modern connectivity
• Systems needing dual-channel DDR5 memory and PCIe 4.0/5.0 expansion

When it may not be suitable

This tray-packaged processor is supplied without a cooler or retail accessories, so an appropriate cooling solution and compatible FCLGA1851 motherboard are required. It may be excessive for very basic office tasks or legacy motherboards that do not support the FCLGA1851 socket, DDR5 memory, or PCIe 5.0 devices.

Key specifications

• Processor family: Intel Core Ultra 5 250K Plus
• CPU cores: 18 (64-bit)
• Smart Cache: 30 MB
• NPU performance: up to 30 TOPs (Intel AI Boost)
• Integrated graphics: Intel Graphics (base 300 MHz, boost up to 1900 MHz)
• Memory support: Dual-channel DDR5, up to 256 GB
• Chip socket: FCLGA1851
• PCI Express: PCIe 4.0 and PCIe 5.0 support

How to use

Install the processor into a compatible motherboard with an FCLGA1851 socket following the motherboard manufacturer’s instructions. Apply a suitable thermal solution and thermal interface material before mounting a cooler. Configure BIOS/UEFI settings for DDR5 memory and enable platform features such as PCIe lanes and integrated graphics as needed. Install drivers for integrated graphics and AI frameworks to use the NPU acceleration.

What to consider before purchase

• Ensure motherboard compatibility with FCLGA1851 socket and BIOS support
• Confirm support for DDR5 memory and desired maximum capacity (up to 256 GB)
• Plan for a separate CPU cooler since the tray version does not include one
• Check whether your workloads will benefit from NPU acceleration and PCIe 4.0/5.0 connectivity

Usage recommendations

For best results in AI inference and multimedia workloads, pair the processor with high-speed DDR5 RAM, a motherboard supporting PCIe 5.0, and a quality cooling solution. Keep system firmware and drivers up to date to fully utilise integrated graphics and NPU features.
