What the Core i3-8300 is
The Core i3-8300 pairs four Coffee Lake cores with extra cache for office towers. It launched in the second quarter of 2018 with a fixed 3.7 GHz and no Turbo at 62 W. Intel positions it above 8100 for buyers who want more cache without more cores.
Eight megabytes of Smart Cache keep more threads resident than 6 MB siblings. The high fixed clock sustains interaction in shared PCs. Four threads without Hyper-Threading cover foreground plus background services.
UHD Graphics 630 from 350 MHz to 1150 MHz handle office displays. The process is 14 nm. DDR4-2400 ECC suits small offices. Note the 62 W rating per Intel ARK, not rounded to 65 W.
Socket and motherboard compatibility
The 8300 fits LGA 1151 on revision 2 boards only. B360 towers pair it with DDR4 for general offices. Early Z370 may need a BIOS update. Revision 1 never works.
DDR4-2400 in two channels up to 64 GB per Intel covers office multitasking. The Socket vs chipset: what decides whether a CPU works guide explains board generations.
Single socket desktops are standard. Another 300 series i3 on the same board adjusts cache and clocks.
Memory, PCIe and cooling
DDR4-2400 in two channels up to 64 GB with SSDs gives responsive offices. Start with 8 GB.
Sixteen Gen3 lanes support NVMe while integrated graphics drive monitors. Most builds skip discrete cards.
62 W stock cooling from the CPU cooler compatibility by socket guide handles office heat.
Upgrade paths
On the same socket, the Intel Core i3-8100T trims to 35 W with less cache for small cases. Core i5 parts add cores where listed. Both share 300 series boards.
Pentium Gold parts suit single app terminals with fewer threads.
Past LGA 1151 office quads move to LGA 1200. The 8300 covers cached quad core desks where 62 W must last.
