Intel Core Ultra 5 225U vs Intel Core Ultra 5 235U
Intel Core Ultra 5 225U
► remove from comparison
The Intel Core Ultra 5 225U is an upper mid-range CPU with 12 cores from the Meteor Lake U series, which was introduced at the beginning of 2025. The chip is similar to the Meteor Lake U series, but the compute part is manufactured in the modern Intel 3 process and therefore offers higher clock rates.
The SoC continues to rely on a tile/chiplet design. The smaller compute tile (compared to the H processors) offers 2 performance cores (P cores, Redwood Cove architecture, SMT) and 8 efficiency cores (E cores, Crestmont architecture). The P-cores support hyperthreading (therefore 14 threads together) and clock up to 4.8 GHz. The E-cores clock at a maximum of 3.8 GHz. In addition, there are now two more low-power efficiency cores with up to 2.4 GHz on the low-power island; the compute tile can therefore be completely deactivated when idle and during simple tasks in order to save power.
Performance
Due to the higher clock rates and the support of faster memory, the performance is slightly below the old top model Core Ultra 7 165U (12 cores, max 4.9 / 3.8 GHz) and well ahead of the old Core Ultra 5 135U (12 cores, max 4.4 / 3.6 GHz).
Graphics unit
The Core Ultra 5 225U offers a new Arc-based iGPU called Intel Graphics with 4 Xe cores and 64 EUs that reach a maximum of 2 GHz. However, the performance is far below the new Arc iGPU in the H series.
Features
Arrow Lake-U has integrated WiFi 6E (WiFi 7 optional). The integrated memory controller now supports LPDDR5/x-8400 or DDR5-6400 (max. 128 GB). A dedicated NPU (2x Gen3 Neural Compute Engines) is now used. The Xe Media Engine supports MPEG-2, AVC, VC-1 Decode, JPEG, VP8 Decode, VP9, HEVC and AV1 Decode up to 8K 10-bit HDR. The chip now supports PCIe-5.0 (x8 for GPU) and PCIe-4.0 (three x12 for SSDs).
Power consumption
The Intel Core Ultra 5 225U is specified with 15 watts TDP (base) and 57 watts (PL2) max. turbo power. Meteor Lake consists of five individual chips, whereby the processor part is manufactured using the new Intel 3 process (5 nm). The graphics unit is produced at TSMC in N5 and the SoC and I/O tile in the older N6 process. These 4 chips are then applied to the 22 nm base tile using the Foveros process.
