Eight cores up to 5.0 GHz

The Intel Core i9-9900 is a desktop processor with eight cores and sixteen threads. It reaches a maximum turbo frequency of 5.0 GHz and fits the LGA1151 socket. The chip is designed for Intel 300 Series chipset motherboards and carries a 65 W thermal design power.

Suits 300 Series builds needing high single-thread

This CPU matches systems built on Intel 300 Series platforms that require strong per-core performance. A BIOS update may be required for motherboard compatibility. Buyers using other chipsets or needing a bundled cooler should consider different options.

65 W TDP at 5.0 GHz peak

The 65 W thermal design power is the key specification for cooler selection and case airflow planning. It defines the heat output the cooling solution must handle when the processor hits its 5.0 GHz maximum turbo frequency.
