Understanding Intel Core i9-9900X @ 3.50GHz

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 i9-9900X @ 3.50GHz work with my motherboard?

The source lists FCLGA2066 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) i9-9900X CPU @ 3.50GHz, Intel Core i9-9900X CPU @ 3.50GHz.

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.
