Intel Core Ultra 7 255U vs Intel Core Ultra 7 265U: Comparison
What is the difference between Core Ultra 7 255U and Core Ultra 7 265U?
They are built to different briefs, and p-core boost clock shows it, Core Ultra 7 255U 5.2 GHz against Core Ultra 7 265U 5.3 GHz. Cinebench 2024 (Multi-Core) backs the spec sheet up. Core Ultra 7 265U scores 523 to 521, 0% clear. There is a split on p-core base clock as well, 2.0 GHz on the Core Ultra 7 255U versus 2.1 GHz on the Core Ultra 7 265U. There is a split on microarchitecture as well, Arrow Lake on the Core Ultra 7 255U versus Intel Core Ultra Processors on the Core Ultra 7 265U.
Core Ultra 7 255U vs Core Ultra 7 265U: which one fits your build
The Core Ultra 7 255U is the one to take for mainstream and business thin-and-light laptops and snappy office work, browsing and video calls, though it is the wrong buy for gaming beyond older or light titles at low settings and copilot+ PC AI features, which need a 40+ TOPS NPU. It is the wrong buy for heavy video rendering or code compiling, where H-series chips finish sooner. The Core Ultra 7 265U suits premium business thin-and-light laptops and fast, responsive office work, browsing and video calls, though it is not built for gaming beyond older or light titles at low settings and copilot+ PC AI features, which need a 40+ TOPS NPU. Avoid it for heavy video rendering or code compiling, where H-series chips finish sooner.
Where the two are identical
Where they agree, they agree completely, total cores, performance cores, efficiency cores, low power cores and total threads included, so the decision does not turn on any of those. They match on 29 further specifications as well.
Is the E-Core Boost Clock the same on the Core Ultra 7 255U and Core Ultra 7 265U?
It is. Both are listed at 4.2 GHz, so it is not a reason to pick one over the other.
