Intel Core Ultra 5 225T vs Intel Core Ultra 7 155UL: Comparison
Core Ultra 5 225T vs Core Ultra 7 155UL: the l3 cache difference
On l3 cache the spread is 40%, Core Ultra 5 225T 20 MB against Core Ultra 7 155UL 12 MB, so Core Ultra 5 225T takes it. P-core base clock is not the same on both, 2.5 GHz on the Core Ultra 5 225T versus 1.7 GHz on the Core Ultra 7 155UL. They differ on tdp too, 35 W on the Core Ultra 5 225T versus 15 W on the Core Ultra 7 155UL. Form factor is not the same on both, Desktop on the Core Ultra 5 225T versus Embedded on the Core Ultra 7 155UL.
Who each one is for
Buy the Core Ultra 5 225T for small-form-factor and mini-PC builds and low-noise home or office desktops, though it is the wrong buy for peak multi-core performance needs and gaming-focused desktop builds. The Core Ultra 7 155UL is the one to take for embedded systems and all-in-one PCs, though it is not built for traditional laptop designs and maximum core-count workloads. Our rating of the Core Ultra 5 225T (7.9/10): A sensible low-power pick for compact Arrow Lake desktop builds where the standard 65W Core Ultra 5 225 would run too hot or too loud. Our rating of the Core Ultra 7 155UL (8/10): the Intel Core Ultra 7 155UL packages Intel's mobile Core Ultra silicon onto a socketed LGA platform for embedded and all-in-one system designs.
