Intel Core Ultra 5 225F 3.3GHz 6x P-Cores 4x E-Cores LGA1851

Description

Arrow Lake at 65W — Without the iGPU

The 225F is the no-graphics variant of the Core Ultra 5 225, sharing the same TSMC 3nm compute tile, identical clocks, cache, and power envelope. The “F” designation removes the Xe-LPG integrated graphics tile, making it the right choice for builders who are pairing this chip with a discrete GPU and want to save slightly over the 225 with iGPU. The hybrid core design features 6 Lion Cove P-cores handling demanding, latency-sensitive workloads and 4 Skymont E-cores managing background tasks and multithreading. Intel Thread Director is embedded in silicon, dynamically routing workloads to the correct core type in real time. The multiplier is locked — this is a non-K SKU — but the platform itself is fully capable for builders who don’t need overclocking.

NPU AI Acceleration Still Included

Despite the no-graphics designation, the 225F retains the Intel AI Boost NPU delivering up to 13 TOPS — the same NPU performance as the 225. This means AI-accelerated features in compatible applications remain available, including Windows Studio Effects, OpenVINO workloads, and DirectML-based AI inference, making it a more capable platform entry than older budget processors despite the locked multiplier.

Platform Considerations

The 225F sits on the LGA 1851 socket, requiring an Intel 800-series motherboard — B860, H870, or Z890 boards all work. DDR5 memory up to 6400 MT/s is officially supported in single DIMM-per-channel configurations, and ECC memory is supported on compatible motherboards. PCIe 5.0 and 4.0 provide up to 24 combined lanes for GPU and NVMe storage connectivity. A discrete GPU is required for all display output as there is no integrated graphics.

⚠️ No integrated graphics — a discrete GPU must be installed for display output.

⚠️ No cooler included — a quality tower air cooler is sufficient for this 65W processor.
