What the Core i3-8100T is
The Core i3-8100T brings four Coffee Lake cores to low power towers without Turbo. It launched in April 2018 with a fixed 3.1 GHz at 35 W. Intel positions T parts for small offices that need quad cores with minimal heat.
Six megabytes of cache support office multitasking across four threads. The fixed clock keeps behavior steady for shared PCs. Four threads without Hyper-Threading cover foreground plus updates.
UHD Graphics 630 from 350 MHz to 1100 MHz drive office displays. The process is 14 nm. DDR4-2400 ECC works where boards validate it.
Socket and motherboard compatibility
The 8100T fits LGA 1151 on revision 2 boards only. H310 small towers pair it with DDR4 for quiet offices. Early Z370 may need a BIOS update. Revision 1 never supports it.
DDR4-2400 in two channels up to 64 GB per Intel suits quad core offices. The Socket vs chipset: what decides whether a CPU works guide explains board generations.
Single socket compact towers are the home. Another 300 series i3 on the same board adds speed.
Memory, PCIe and cooling
DDR4-2400 in two channels up to 64 GB with SSDs gives smooth offices. Start with 8 GB.
Sixteen Gen3 lanes can hold 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 i3-8300T raises cache to 8 MB at the same 35 W for heavier multitasking. The Intel Core i3-9100T moves to 9th Gen Refresh at the same 35 W where listed. Both share 300 series boards.
Pentium Gold parts trim cache and Turbo for cheaper terminals.
Past LGA 1151 low power quads move to LGA 1200. The 8100T covers quiet quad core offices.
