Intel Core Ultra 5 125UL vs Intel Core Ultra 5 225T: Comparison
Core Ultra 5 125UL vs Core Ultra 5 225T l3 cache compared
Start with l3 cache, because it is the widest measured gap between them: Core Ultra 5 125UL 12 MB against Core Ultra 5 225T 20 MB, 40% in favour of Core Ultra 5 225T. There is a split on p-core base clock as well, 1.3 GHz on the Core Ultra 5 125UL versus 2.5 GHz on the Core Ultra 5 225T. They differ on tdp too, 15 W on the Core Ultra 5 125UL versus 35 W on the Core Ultra 5 225T. They differ on form factor too, Embedded on the Core Ultra 5 125UL versus Desktop on the Core Ultra 5 225T.
Who each one is for
Buy the Core Ultra 5 125UL for embedded systems and all-in-one PCs, though it is the wrong buy for traditional laptop designs and maximum core-count workloads. The Core Ultra 5 225T suits small-form-factor and mini-PC builds and low-noise home or office desktops, though it is not the pick for peak multi-core performance needs and gaming-focused desktop builds. Our rating of the Core Ultra 5 125UL (8/10): the Intel Core Ultra 5 125UL packages Intel's mobile Core Ultra silicon onto a socketed LGA platform for embedded and all-in-one system designs. 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.
