Specification context
The Intel Core Ultra 7 255U is a Laptop released in 2025. Recorded specifications include a 15 W reference TDP, a 17,857 CPU Mark. Use these figures to understand its position, then compare the results with your software and the complete platform.
The 17,857 CPU Mark is a broad overall-performance measure, while the 3,643 single-thread result adds context for less-parallel work. Compare the nearby alternatives on this page and do not treat one score as a verdict for every application.
No confirmed socket is recorded for this processor. Verify the exact device or motherboard with the manufacturer before planning an upgrade.
Recorded memory support: DDR5-6400. The 15 W TDP helps size the cooling class, but it is not the same as peak wall-power consumption.
FAQ
The main recorded details are a 15 W reference TDP, a 17,857 CPU Mark. The tables on this page show socket, memory, cache and graphics data when available.
The product name or CPU Mark alone cannot answer that. Check single-thread performance, core count, the target graphics card, gaming resolution and results from the games you play.
A confirmed socket is not recorded here. Use the device model or manufacturer specifications to identify compatible hardware.
The recorded reference TDP is 15 W. Real consumption can be lower or higher depending on power limits, motherboard, workload and cooling.
This guidance interprets recorded specifications and results; it does not claim hands-on device testing. Results can vary with motherboard, power, memory and cooling.
