What the Core i7-7820HK is
The Core i7-7820HK is a four core, eight thread unlocked mobile processor from Kaby Lake-H. It launched in January 2017 with a 2.9 GHz base and up to 3.9 GHz Turbo at 45 W. Four cores with Hyper-Threading plus an open multiplier cover tuning laptops where overclocking headroom matters.
Eight megabytes of cache feed gaming with streaming and creation. The 2.9 GHz base sustains loads, while 3.9 GHz burst gives strong peaks. Forty five watts with tuning headroom need robust dual fan cooling.
HD Graphics 630 drives setup displays, while gaming bodies rely on discrete GPUs for play. Hardware decode keeps streaming smooth. Eight threads help multitasking beyond quad cores without threads.
On 14 nm the 7820HK is the tuning flagship of Kaby Lake-H mobile. Enthusiast laptops offer unlocked firmware for it. Soldered mounting keeps tuning to clocks and power limits.
Socket and motherboard compatibility
The 7820HK solders to BGA 1440 with no socket swap. Laptop model with unlocked firmware is required for tuning. Standard H boards run it at stock clocks.
DDR4 in two channels feeds the chip. Discrete GPUs take PCIe lanes for gaming. The How to find your CPU socket type guide covers BGA identification.
The Intel Core i7-7820HQ on the same package is the locked business version. The Intel Core i7-7700HQ trims cache where cost matters.
Memory, PCIe and cooling
DDR4-2400 in two channels is the memory design. Matched kits help minimum frame times. Capacity follows board slots.
Sixteen PCIe lanes wire graphics plus NVMe storage. Tuning laptops prioritize GPU bandwidth. Extra storage hangs off chipset lanes.
Forty five watts with tuning need strong dual fan cooling. Power limits in firmware decide sustained clocks more than silicon.
Upgrade paths
No CPU change is possible on soldered BGA 1440. Tuning headroom is the only performance lever, within thermal limits.
Past this generation a new laptop brings more cores. SSD and memory where socketed extend life.
