Intel Core i9-8950HK socket: BGA 1440

What the Core i9-8950HK is

The Core i9-8950HK is a six core, twelve thread mobile processor with a 2.9 GHz base and up to 4.8 GHz boost. It carries 12 MB of Smart Cache and a 45 W TDP on the 14 nm process. Intel ARK marks Thermal Velocity Boost and an unlocked HK suffix, which is rare for soldered laptop chips.

It led the Coffee Lake-H launch in the second quarter of 2018 as the first Core i9 for laptops. Six cores with Hyper-Threading cover play, streaming and rendering in thick flagship bodies with strong cooling. The unlocked multiplier allows tuning where the laptop BIOS exposes it, though heat quickly becomes the limit.

UHD Graphics 630 runs from 350 MHz base to 1.20 GHz max for setup displays, while play runs on the discrete GPU. Memory runs as DDR4-2666 or LPDDR3-2133 in two channels up to 64 GB. The chip is soldered in the FCBGA1440 package at 42 by 28 mm.

Socket and motherboard compatibility

The 8950HK is soldered to the board in the BGA 1440 package and cannot be replaced. Upgrading means replacing the board or the whole laptop, so buyers should choose the GPU tier, display and memory size at order time. Flagship makers pair it with large heat pipes and dual fans tuned for 45 W plus turbo headroom.

Intel ARK lists Sockets Supported as FCBGA1440 with a 42 by 28 mm package. Boards wire the 16 PCIe 3.0 lanes to a fast discrete GPU for high refresh play. Tuning headroom depends on the maker BIOS, since some lock the multiplier despite the HK suffix.

There is no socket retention or aftermarket mounting choice. Service follows the laptop maker manual for fan cleaning and repasting, which matters more on a tuned flagship. The Intel Core i5-10200H shows a later mainstream 45 W path on the same package without tuning.

Memory, PCIe and cooling

Memory support covers DDR4-2666 modules or LPDDR3-2133 in two channels up to 64 GB, with up to 41.8 GB per sec of bandwidth. Two matched SODIMMs give dual channel speed for play beside creation. Flagship laptops often ship 16 or 32 GB, which covers streaming and editing beside games.

PCI Express arrives as version 3.0 with 16 lanes from the CPU, wired as one by 16, two by 8, or one by 8 plus two by 4. Designs typically give the full link to the discrete GPU for high refresh panels. Storage runs through chipset lanes where the board provides extra NVMe slots.

Upgrade paths

There is no CPU upgrade path on BGA 1440. The only moves are more memory where SODIMM slots allow it, larger SSDs, or a whole laptop replacement. Buyers who keep laptops for years should buy the GPU and display they want at order time, since neither changes later.

Staying on this board, tuned profiles need care with heat and fan noise. The unlocked multiplier is a bonus rather than a promise in thin flagship bodies.
