Understanding Intel Core Ultra X9 388H

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.

Will Intel Core Ultra X9 388H work with my motherboard?

The source lists FCBGA2540 as the socket. Check the exact motherboard model and revision on its manufacturer's CPU support list, including the minimum BIOS version. A socket match alone does not establish compatibility. Include a new motherboard, memory and cooling in your budget when the platform changes.

Other names listed by the benchmark source: Intel(R) Core(TM) Ultra X9 388H.

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.
