Understanding Intel Core Ultra 7 255U

PassMark single-core and multicore scores describe different workloads. Compare each score with the same benchmark on another processor. A higher multicore score does not mean every application or game will run proportionally faster. Device cooling, memory and power settings also affect performance.

How much RAM or storage does Intel Core Ultra 7 255U have?

The processor name does not identify your device's installed RAM or storage. Devices using the same chipset can have different memory configurations. Find your exact model in Settings, under About phone or About tablet, then check that model's specifications on the device manufacturer's website. Menu names vary by device.

RAM capacity, storage capacity and supported memory types are different specifications. Benchmark scores and CPU core counts cannot tell you how many GB your device has.

Other names listed by the benchmark source: Intel(R) Core(TM) Ultra 7 255U.

Sources and data freshness

The retrieval date records when Find Me a CPU collected the source data. It is not a benchmark test date. Prices are USD estimates from the source, converted for other currencies, rather than live retailer offers. Release / first seen means the CPU first appeared on PassMark charts, not necessarily its launch date.

Benchmark scores do not predict frame rates in a particular game. Typical TDP is a specification, not measured electricity use. A matching socket does not confirm motherboard support; check the manufacturer's CPU support list and BIOS requirements.
