Eight-core Coffee Lake desktop processor

The Intel Core i9-9900K is an eight-core, sixteen-thread desktop processor built on the Coffee Lake architecture. It fits the LGA 1151 socket on 300-series motherboards and ships in a boxed package. A base frequency of 3.6 GHz and 16 MB of cache give strong single-thread and multi-thread throughput for demanding workloads.

Integrated graphics and memory support

The chip includes Intel UHD Graphics 630 for display output without a discrete card. System memory support extends to DDR4 4400, allowing high-speed kits to run at their rated frequency. Power draw and acoustic profile in typical desktop use will depend on the cooler and motherboard power limits chosen by the builder.

Behaviour under sustained load

Under prolonged heavy work all eight cores remain active and the processor can maintain elevated frequencies within its thermal envelope. The unlocked multiplier permits manual tuning for higher clocks when cooling and power delivery allow. Actual steady-state speeds and temperatures are determined by the specific cooling solution and case airflow installed.
