Intel Core i3-10300 socket: LGA 1200

What the Core i3-10300 is

The Core i3-10300 is a four core, eight thread processor from the 10th Gen Comet Lake family. It launched in April 2020 as the upper mainstream i3, above the i3-10100. Hyper-Threading is enabled across all four cores, which lifts multitasking well above dual core Pentiums.

The base clock is 3.7 GHz with up to 4.4 GHz single core boost through Turbo Boost 2.0. All core load settles near 4.2 GHz on boards with adequate cooling. Eight megabytes of L3 support the four cores in games and office suites that spill beyond small caches.

UHD Graphics 630 with up to 1.15 GHz burst covers office displays and 4K video playback without a card. The 65 W rating fits stock cooling and entry boards. For budget gaming with a discrete card, this i3 often marks the point where four threads stop being the limit.

Socket and motherboard compatibility

The i3-10300 fits LGA 1200 on every 400 and 500 series board. Comet Lake is native on both series, so the chip posts without a BIOS update. B460, H410, B560 and H510 are the cost effective choices for a locked 65 W part.

Z490 and Z590 also work and add memory tuning headroom, though the CPU multiplier stays locked. Power needs are modest, but a board with heatsinks on the power stages holds boost longer under sustained loads. Boards for LGA 1151 do not accept the chip.

Office fleets often pair this i3 with Q470, W480, Q570 or W580 for management and ECC board features, even though the CPU itself lacks ECC. The Socket vs chipset: what decides whether a CPU works guide details which 400 series boards can later take an 11th Gen Rocket Lake chip.

Memory, PCIe and cooling

DDR4-2666 is the official memory speed in two channels up to 128 GB. Faster XMP kits can run above spec on Z boards, but the controller rating stays at 2666. Dual channel operation matters for both games and integrated graphics.

Sixteen PCIe 3.0 lanes from the CPU feed graphics and NVMe. A mid range card from 2020 plus one NVMe SSD fits comfortably. Chipset lanes add SATA and extra M.2 slots for bulk storage.

The 75 mm LGA 1200 mounting pattern matches older Intel coolers. Boxed i3-10300 units include a stock cooler that holds 65 W in ventilated cases. A small tower lowers noise and sustains boost in warm rooms. The CPU cooler compatibility by socket guide lists compatible brackets.

Upgrade paths

On LGA 1200 the Core i5-10400 adds two cores for streaming and compilation, while the Core i7-10700 adds eight cores for heavy multitasking. Both reuse board and DDR4. The i3 to i5 step is the most cost effective gaming lift of this generation.

An 11th Gen Rocket Lake chip such as the Intel Core i5-11400 needs a 500 series board or a compatible 400 series board with a BIOS update, and brings PCIe 4.0 on supported boards. A full move to LGA 1700 opens DDR5 and newer cores at the price of a new board.
