Intel Core i7-7700 7th Gen Desktop Processor, 4-Core, LGA1151
The Intel Core i7-7700 is a desktop processor with four cores and eight threads, built on Intel's 7th generation Core architecture, codenamed Kaby Lake. It runs at a base frequency of 3.60 GHz and reaches 4.20 GHz under Turbo Boost, backed by 8 MB of Intel Smart Cache within a 65 W thermal envelope. It installs in an FCLGA1151 socket and supports either DDR4 at up to 2400 MT/s or DDR3L at up to 1600 MT/s, which suits it to mainstream desktop and industrial systems that need Hyper-Threading.

Compatibility and integration considerations
This processor runs natively on Intel 200 series chipsets such as B250, H270 and Z270, and on 100 series boards only after a BIOS update, so confirm the board's processor support list and firmware revision before ordering against an existing platform. The FCLGA1151 socket is also used by the 8th and 9th generation Core parts, which require 300 series boards and cannot substitute for this one. Memory runs in dual channel as either DDR4 at up to 2400 MT/s or DDR3L at up to 1600 MT/s with a 64 GB ceiling, and ECC is not supported. Integrated Intel HD Graphics 630 requires display outputs on the board, and cooling should be rated for 65 W, the same envelope as the four core i5 parts of this generation despite the higher clocks and Hyper-Threading.
Typical use cases
This processor is the top four core Kaby Lake desktop part without an unlocked multiplier, so it appears in workstations, thin clients and industrial PCs that were qualified on 200 series boards and need eight threads rather than four. Most demand is replacement and fleet maintenance, either swapping a failed unit or upgrading an i5 board that is already validated, which avoids requalifying the platform on a newer socket.
