Intel Core Ultra 5 235H vs Intel Core Ultra 7 255H: Comparison
What is the difference between Core Ultra 5 235H and Core Ultra 7 255H?
Expect a near tie. The closest thing to a difference is total cores, Core Ultra 5 235H 14 against Core Ultra 7 255H 16. Measured rather than claimed: in Geekbench 6 (Single-Core) the Core Ultra 7 255H returns 2,806 against 2,727, a 3% lead. L3 cache runs the same way, 18 MB on the Core Ultra 5 235H versus 24 MB on the Core Ultra 7 255H, another win for Core Ultra 7 255H.
Who each one is for
The Core Ultra 5 235H suits business laptops managed by IT with Intel vPro and coding, photo editing and heavy multitasking, though it is not the pick for copilot+ PC AI features, which need a 40+ TOPS NPU and demanding modern games without a dedicated GPU. It is the wrong buy for home buyers who do not need vPro and want the lowest price. The Core Ultra 7 255H is the one to take for premium thin laptops for work and creative apps and gaming laptops paired with a dedicated GPU, though it is not built for copilot+ PC AI features, which need a 40+ TOPS NPU and demanding games on integrated graphics alone. It is not the one for buyers who want the longest battery life, where 200V laptops fit better.
What Core Ultra 5 235H and Core Ultra 7 255H have in common
Everything else lines up. Efficiency cores, low power cores, e-core boost clock, tdp and integrated graphics read the same on both, so those are not worth weighing. They match on 24 further specifications as well.
Do the Core Ultra 5 235H and Core Ultra 7 255H differ on performance cores?
Yes. Performance Cores reads 4 on the Core Ultra 5 235H versus 6 on the Core Ultra 7 255H.
Is the Socket the same on the Core Ultra 5 235H and Core Ultra 7 255H?
It is. Both are listed at FCBGA2049, so it is not a reason to pick one over the other.
