Intel Core Ultra 7 251HX vs Intel Core Ultra 7 270HX Plus: Comparison
Core Ultra 7 251HX vs Core Ultra 7 270HX Plus total cores compared
Expect a near tie. The closest thing to a difference is total cores, Core Ultra 7 251HX 18 against Core Ultra 7 270HX Plus 20.
Core Ultra 7 251HX vs Core Ultra 7 270HX Plus: which one fits your build
Buy the Core Ultra 7 251HX for gaming laptops with a dedicated graphics card and streaming, photo editing and moderate video work, though it is the wrong buy 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 HX-class speed without paying for a Core Ultra 9. It is the wrong buy for hours of heavy rendering, where chips with more performance cores finish sooner. The Core Ultra 7 270HX Plus suits 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 the pick for thin and light laptops where battery life comes first and copilot+ PC AI features, which need a 40+ TOPS NPU. It is equally the pick for 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.
What Core Ultra 7 251HX and Core Ultra 7 270HX Plus have in common
Where they agree, they agree completely, efficiency cores, low power cores, tdp, l3 cache and integrated graphics included, so the decision does not turn on any of those. They match on 23 further specifications as well.
Do the Core Ultra 7 251HX and Core Ultra 7 270HX Plus differ on total threads?
Yes. Total Threads reads 18 on the Core Ultra 7 251HX versus 20 on the Core Ultra 7 270HX Plus.
Is the Socket the same on the Core Ultra 7 251HX and Core Ultra 7 270HX Plus?
It is. Both are listed at FCBGA2114, so it is not a reason to pick one over the other.
