Intel Core i3-8100T 8th Gen Desktop Processor, 4-Core, LGA1151
The Intel Core i3-8100T is a low power desktop processor with four cores and four threads, built on Intel's 8th generation Core architecture, codenamed Coffee Lake. It runs at a fixed 3.10 GHz with no Turbo Boost, backed by 6 MB of Intel Smart Cache within a 35 W thermal envelope that can be configured down to 25 W at 2.40 GHz. It installs in an FCLGA1151 socket on 300 series boards and supports dual channel DDR4 at up to 2400 MT/s, which suits it to small form factor and fanless systems where thermal headroom is the limit.

Compatibility and integration considerations
The FCLGA1151 socket is shared with earlier Intel generations, but this processor runs only on 300 series chipsets, which Intel lists as B360, B365, H310, H370, Q370, Z370 and Z390. It will not boot on 100 or 200 series boards even though it fits the socket, so verify the chipset rather than the socket when ordering against an existing platform. Boards that shipped before this generation launched may need a BIOS update before they will post. The 35 W envelope and the 25 W configurable TDP-down mode are what make this part fit small form factor and fanless chassis, but the TDP-down mode also drops the base clock to 2.40 GHz, so confirm which mode the board firmware selects before assuming full clocks. Memory runs in dual channel DDR4 at up to 2400 MT/s with a 64 GB ceiling and ECC is not supported. Integrated Intel UHD Graphics 630 requires display outputs on the board.
Typical use cases
This processor is the low power version of the entry four core Coffee Lake desktop part, so it appears in mini PCs, thin clients, digital signage players and fanless industrial boxes where a 65 W part will not fit the thermal budget. It has no Turbo Boost, which keeps power and acoustics flat under sustained load. Most demand is replacement and fleet maintenance on 300 series platforms that were qualified around the 35 W envelope and cannot absorb a hotter substitute.
