BGA 1787 socket: CPUs, chipsets and cooler fit
BGA 1787 is the Intel soldered ball grid array package with 1787 balls for Tiger Lake-H45 mobile processors from May 2021 plus BGA desktop parts. The package measures 50 × 26.5 mm and solders directly to gaming laptop boards and small desktop carriers. There is no socketed upgrade path.

Overview
The platform pairs Willow Cove cores with Gen4 graphics and storage links for gaming laptops that also create and stream. Core counts span 6 cores with 12 threads on Core i5 parts to 8 cores with 16 threads on Core i7 parts. Cache follows the die from 12 MB to 24 MB of Intel Smart Cache. Memory runs DDR4 up to 3200 MT/s in two channels to 128 GB.
Because the processor solders to the board there is no socket retention and no processor upgrade. Laptop makers design cooling around the 45 W base with headroom for 109 W turbo bursts, and buyers choose the configuration once at order time. Against BGA 1449 for 4-core H35 thin laptops, BGA 1787 is the larger gaming option with full Gen4 graphics lanes.
Processor generations
| Codename | Marketing name | Years | Notes |
|---|---|---|---|
| Tiger Lake-H | 11th Gen Core H45 and B series | 2021 | Gaming laptop processors with 6 to 8 Willow Cove cores plus 65 W BGA desktop parts, launched in May 2021 with Gen4 links. |
Who BGA 1787 serves
BGA 1787 processors belong in gaming laptops, mobile workstations and small desktop carriers where sustained clocks matter more than battery life. The 45 W base with 109 W turbo headroom separates them from thin-and-light designs that trade sustained clocks for silence.
Within the package the choice runs from the 6-core Core i5-11260H for mainstream gaming through the Core i5-11400H and i5-11500H to 8-core Core i7 parts for creation alongside play. Graphics stay UHD tier for displays, since gaming bodies carry discrete GPUs on the Gen4 lanes. Makers can configure thermals down to 35 W on H45 parts for thinner gaming bodies.
Memory and PCIe
Memory support spans DDR4 up to 3200 MT/s across two channels to 128 GB. SODIMM boards allow later memory changes, and dual-channel fitting stays mandatory for smooth play. ECC is not offered on these consumer mobile parts. ECC is absent, so buyers who need error correction choose workstation platforms instead.
PCIe arrives as Gen4 with 20 lanes from the CPU for discrete graphics and NVMe, with PCH lanes behind them for board devices. Laptop designs typically wire 16 lanes to graphics with 4 lanes to fast NVMe storage.

Frequently asked questions
Can a BGA 1787 processor be replaced or upgraded?
No. The processor is soldered to the board. Upgrading means replacing the board or the whole laptop, so choose core count and memory at order time.
What is the difference between BGA 1787 and BGA 1449?
BGA 1787 at 50 × 26.5 mm serves 6 and 8-core H45 gaming parts with 20 Gen4 lanes. BGA 1449 at 45.5 × 25 mm serves 4-core H35 thin laptops with fewer lanes.
What memory does BGA 1787 use?
DDR4 up to 3200 MT/s across two channels to 128 GB, decided per board.
Does BGA 1787 support PCIe Gen4?
Yes, 20 Gen4 lanes from the CPU for discrete graphics and NVMe storage.
What is the TDP range on BGA 1787?
45 W base with up to 109 W turbo on H45 gaming parts, and 65 W on B desktop parts for small carriers.
