Intel Core Ultra 7 255HX vs Intel Core Ultra 7 270HX Plus: Comparison
What is the difference between Core Ultra 7 255HX and Core Ultra 7 270HX Plus?
The first real difference is p-core boost clock: Core Ultra 7 255HX 5.2 GHz against Core Ultra 7 270HX Plus 5.3 GHz. They differ on memory type too, DDR5 on the Core Ultra 7 255HX versus DDR5 up to 6400 MT/s on the Core Ultra 7 270HX Plus.
Who each one is for
The Core Ultra 7 255HX is the one to take for high-end gaming laptops and mobile content creation, though it is not the pick for thin-and-light laptops and battery-life-focused use. Buy the Core Ultra 7 270HX Plus for gaming laptops with a mid-range to high-end graphics card and video editing, streaming and code builds on the go, though it is not built for thin and light laptops where battery life comes first and copilot+ PC AI features, which need a 40+ TOPS NPU. It also earns its place with buyers who want near top-tier HX speed without Core Ultra 9 pricing. It is not the one for budget buyers, since an HX chip raises laptop cost and weight. Our rating of the Core Ultra 7 255HX (8.8/10): the Intel Core Ultra 7 255HX brings desktop-class core counts to a mobile package, suited to high-end gaming and creator laptops that can handle the higher TDP.
What Core Ultra 7 255HX and Core Ultra 7 270HX Plus have in common
Where they agree, they agree completely, total cores, performance cores, efficiency cores, total threads and p-core base clock included, so the decision does not turn on any of those. They match on 8 further specifications as well.
Do the Core Ultra 7 255HX and Core Ultra 7 270HX Plus differ on socket?
Yes. Socket reads BGA 2114 on the Core Ultra 7 255HX versus FCBGA2114 on the Core Ultra 7 270HX Plus.
Is the L3 Cache the same on the Core Ultra 7 255HX and Core Ultra 7 270HX Plus?
It is. Both are listed at 30 MB, so it is not a reason to pick one over the other.
