The Intel Core Ultra 5 225 is a desktop processor with 10 cores, launched in January 2025, at an MSRP of $246. It is part of the Ultra 5 lineup, using the Arrow Lake architecture with Socket 1851. Core Ultra 5 225 has 20 MB of L3 cache and operates at 3.3 GHz by default, but can boost up to 4.9 GHz, depending on the workload. Intel is building the Core Ultra 5 225 on a 3 nm production process using 17,800 million transistors. The silicon die of the chip is not fabricated at Intel, but at the foundry of TSMC. The multiplier is locked on Core Ultra 5 225, which limits its overclocking capabilities.
With a TDP of 65 W, the Core Ultra 5 225 consumes typical power levels for a modern PC. Intel's processor supports DDR5 memory with a dual-channel interface. The highest officially supported memory speed is 6400 MT/s, but with overclocking (and the right memory modules) you can go even higher. For communication with other components in the computer, Core Ultra 5 225 uses a PCI-Express Gen 5 connection. This processor features the Arc Xe-LPG Graphics 16EU integrated graphics solution.
Hardware virtualization is available on the Core Ultra 5 225, which greatly improves virtual machine performance. Additionally, IOMMU virtualization (PCI passthrough) is supported, so that guest virtual machines may directly use host hardware. Programs using Advanced Vector Extensions (AVX) will run on this processor, boosting performance for calculation-heavy applications. Besides AVX, Intel is including the newer AVX2 standard, too, but not AVX-512.
