Intel Core i3-9300 BX80684i39300 desktop processor

Core i3-9300 for everyday desktop builds

The Intel Core i3-9300 is a quad-core desktop processor that runs at 3.7 GHz and reaches 4.3 GHz with Turbo Boost 2.0. It fits the LGA 1151 socket on Intel 300 Series motherboards and includes Intel UHD Graphics 630 for display output without a discrete card. The 62 W thermal design keeps cooling requirements modest for typical office and home systems.

Sustained load behaviour on 14 nm Coffee Lake

Under continuous workloads the chip holds its base frequency within the 62 W envelope, while Turbo Boost 2.0 raises clocks toward 4.3 GHz when thermal headroom allows. Four threads share 8 MB of L3 cache and a dual-channel DDR4 controller, so multi-tasking throughput scales steadily rather than spiking and throttling. The integrated graphics engine idles at 350 MHz and steps up only when the display pipeline demands it.

Installation notes for LGA 1151 300 Series

Seat the processor in the keyed LGA 1151 socket, lower the retention lever, and attach a cooler rated for at least 62 W; the boxed cooler supplied with the BX80684i39300 meets this requirement. Apply a pea-sized dot of thermal paste if the cooler lacks pre-applied material. Verify the motherboard BIOS recognises the 9th Gen Core i3 before installing the operating system, and enable XMP in firmware to run DDR4 at its rated speed.
