What the Core i7-8700T is
The Core i7-8700T packs six cores with Hyper-Threading into a 35 W desktop envelope. It launched in the second quarter of 2018 with a 2.4 GHz base and up to 4.0 GHz boost. Intel positions T parts for small towers that need full features with less heat.
Twelve megabytes of Smart Cache support office multitasking across twelve threads. The modest base clock stretches efficiency in compact cases. Boost to 4.0 GHz lifts single thread bursts in everyday apps.
UHD Graphics 630 from 350 MHz to 1200 MHz drives office displays. The process is 14 nm. DDR4-2666 in two channels with up to 128 GB suits small towers. Intel ARK lists Q2 2018, consistent with April 2018 in lists.
Socket and motherboard compatibility
The 8700T fits LGA 1151 on revision 2 boards only. H310 and B360 small towers pair it with DDR4 for quiet offices. Early Z370 may need a BIOS update. Revision 1 never works.
DDR4-2666 in two channels up to 128 GB covers twelve thread offices. The Socket vs chipset: what decides whether a CPU works guide explains board generations.
Single socket compact towers are the home. Another low power 300 series chip on the same board adjusts performance.
Memory, PCIe and cooling
DDR4-2666 in two channels up to 128 GB with SSDs gives smooth multitasking. Start with 16 GB.
Sixteen Gen3 lanes with 1x16, 2x8 and 1x8 plus 2x4 splits feed NVMe while integrated graphics drive monitors. Most small towers skip discrete cards.
35 W low profile cooling from the CPU cooler compatibility by socket guide stays quiet.
Upgrade paths
On the same socket, the Intel Core i7-8670T trims clocks at the same 35 W for lower cost rooms. The Intel Core i5-8500T drops to six threads for cheaper nodes. Both share 300 series boards.
Pentium parts lack Turbo for bursts.
Past LGA 1151 low power offices move to LGA 1200. The 8700T covers quiet twelve thread towers.
