Intel Core Ultra 5 135UL vs Intel Core Ultra 5 245T: Comparison
What is the difference between Core Ultra 5 135UL and Core Ultra 5 245T?
On l3 cache the spread is 50%, Core Ultra 5 135UL 12 MB against Core Ultra 5 245T 24 MB, so Core Ultra 5 245T takes it. Tdp is not the same on both, 15 W on the Core Ultra 5 135UL versus 35 W on the Core Ultra 5 245T. They differ on form factor too, Embedded on the Core Ultra 5 135UL versus Desktop on the Core Ultra 5 245T. They differ on release year too, 2024 on the Core Ultra 5 135UL versus 2025 on the Core Ultra 5 245T.
Who each one is for
Buy the Core Ultra 5 135UL 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 245T is the one to take for desktop gaming and everyday productivity, though it is not built for laptops and fanless designs. Our rating of the Core Ultra 5 135UL (8/10): the Intel Core Ultra 5 135UL 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 245T (8/10): the Intel Core Ultra 5 245T is a step-up low-power desktop Arrow Lake-S chip, well suited to compact PCs wanting more headroom than the 235T.
Where the two are identical
Where they agree, they agree completely, total threads, integrated graphics, socket, igpu and memory type included, so the decision does not turn on any of those.
