Intel Core Ultra 5 225F vs Intel Core Ultra 5 245K vs Intel Core Ultra 5 235

Intel Core Ultra 5 225F

The Intel Core Ultra 5 225F is a relatively power efficient desktop processor of the Arrow Lake generation. It integrates 10 cores in two clusters. The 6 performance cores (Lion Cove P-Cores) clock from 3.3 to 4.9 GHz and the 4 efficiency cores (Skymont E-Cores) clock from 2.7 to 4.4 GHz. The CPU has access to 20 MB Smart Cache and 22 MB L2 Cache.

Detailed benchmarks and measured values can be found in our detailed test report on the Core Ultra 5 225F.

The F series is specified with a TDP of 65 watts and is therefore also suitable for smaller desktop PCs with air cooling.

Intel Core Ultra 5 235

The Intel Core Ultra 5 235 is a desktop processor based on the Arrow Lake-S series that was introduced at the beginning of 2025. It offers 14 cores divided in 6 performance cores with up to 5 GHz and 8 efficiency cores with up to 4.4 GHz.

The CPU performance is comparable to the old Intel Core i5-13600K and therefore well suited for demanding tasks.

The Arrow Lake-S chips are composed of several chiplets. The CPU part is manufactured at TSMC in the modern N3B (3nm) process, the GPU also comes from TSMC in the N5P process. The SoC and I/O tile are manufactured in the TSMC N6 process. The base tile is manufactured by Intel in the 22nm process and carries the individual chiplets thanks to Fovero's 3D packaging.

The TDP is specified at 65 watts (long-term) to 121 watts (Turbo).
