Intel Core i5-10400H socket: BGA 1440

What the Core i5-10400H is

The Core i5-10400H is a four core, eight thread Comet Lake-H mobile processor. It launched in April 2020 with a 2.6 GHz base and up to 4.6 GHz boost for mainstream gaming laptops. The 500 MHz base lift over the later 10200H gives stronger sustained performance in long sessions.

Eight megabytes of L3 support the four cores in games and office creation. The 45 W envelope suits 15 inch dual fan designs with a discrete GPU. Battery life under load is short, as with all H series parts, since the design favors wall power.

UHD Graphics 630 drives the laptop panel for battery saving modes, while the discrete GPU takes over for play. Optimus style switching depends on the laptop wiring. Four cores remain enough for school, office and 1080p gaming with a mid range card.

Socket and motherboard compatibility

The 10400H solders to BGA 1440 with no upgrade path. Laptop makers pair it with HM470 or QM480 chipsets for ports and security. Board memory may be SODIMM slots for later expansion or soldered for thin bodies.

Cooling is a dual heat pipe assembly sized for 45 W sustained plus turbo spikes. Fan curves in the maker control app decide noise against clocks. The CPU cooler compatibility by socket guide explains why mobile cooling has no retail pattern.

Desktop boards do not accept this package. Even though the codename Comet Lake matches LGA 1200 desktops, the ball layout and firmware are mobile only.

Memory, PCIe and cooling

DDR4-2933 in two channels up to 128 GB is the rated configuration. Gaming laptops ship 8 or 16 GB with a free slot for doubling. Dual channel mode lifts both game minimums and integrated graphics.

Sixteen PCIe 3.0 CPU lanes feed discrete graphics and NVMe. A GTX 1650 class GPU plus a 512 GB NVMe SSD is the typical 10400H recipe. Extra storage hangs off chipset lanes.

The 35 W down configuration lets thin makers cap heat in slim bodies. Full 45 W needs thicker chassis with rear exhaust. Service means fan cleaning and repaste per maker manual, never a socket swap.

Upgrade paths

Soldered BGA leaves no CPU step. Memory to 16 or 32 GB and a larger NVMe SSD are the useful upgrades. A fresh battery restores mobile use where the pack is removable or serviceable.

A laptop change to a 6-core H part such as the Intel Core i7-10750H adds threads for editing. A move to BGA 1744 brings hybrid cores and Gen5 graphics links in a new chassis.
