Understanding AMD Ryzen 9 9900X
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 AMD Ryzen 9 9900X work with my motherboard?
The source lists AM5 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: AMD Ryzen 9 9900X 12-Core Processor.

Sources and data freshness
- AMD Ryzen 9 9900X on PassMark CPU Benchmarks. Data retrieved .
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.
