Intel Core i5-9400 Desktop Processor BX80684I59400

Six-core desktop processor for mainstream builds

The Intel Core i5-9400 delivers six cores and six threads at a 2.9 GHz base frequency with a maximum turbo of 4.1 GHz. It fits LGA 1151 sockets on Intel 300 Series motherboards and includes Intel UHD Graphics 630 for systems without a discrete card.

Sustained workload behaviour within a 65 W envelope

Under continuous load the chip operates at its 65 W thermal design power, relying on the cooler to keep temperatures at or below the 100 °C maximum. Turbo Boost 2.0 raises clocks opportunistically while the power limit and thermal headroom allow.

LGA 1151 socket with Intel 300 Series chipset

This processor is compatible only with motherboards based on Intel 300 Series chipsets, making the socket and chipset pairing the single specification that determines whether it fits a given platform.
