▲ 674,310 ▼

4 Cores, 4 Threads @3.6GHz, Coffee Lake.
Release date: Q4 2017.

Average Bench: 70.6% (388th of 1442)

Based on 81,392 user benchmarks.  Device: BFEBFBFF000906EB Model: Intel(R) Core(TM) i3-8100 CPU @ 3.60GHz

Intel’s i3-8100 from their 8th generation of Core processors is a mainstream quad-core CPU. It is the entry model of the latest Coffee Lake line up with a clock speed of 3.6 GHz. Previously, i3 Kaby Lake processors had two cores with hyperthreading, but now, i3 Coffee Lake processors have 4 cores and offer much better value for money in terms of dollars per core. With a performance profile that closely matches last years mid range Kaby Lake i5's (the then go-to mid range gaming choice) and a price tag of just $120, the i3-8100 represents excellent value for money. Unfortunately, like all Coffe Lake processors, the i3-8100 does require a new 300-series motherboard even though it shares the same LGA1151 socket as the previous generation of Kaby Lake 200 motherboards. Intel were clearly mindful of AMD's similarly priced quad core Ryzen 3 1200 which achieves very comparable single, and quad-core benchmarks to the i3-8100.  [Oct '17 CPUPro]

with four cores and four thread, it is still worse than the Ryzen 3 as it is locked an not overclockable.

It's an i5-7500 for an i3 price, with a modded socket. Intel's response to RYZEN.

Buy this silent beast with a b360m 1050ti and dual channel ram. It is performing very well with %85 bench score.

Great 8th gen CPU. First 4 core I3. Nice to have in a medium build. I think go to the i5 9400f to upgrade a little.

Served me well for 3 years, until i upgraded to an i5-9600K to get rid of the bottleneck with my new GTX 1650. Super good performance, but you can get much better CPUs for a cheaper price today, this one is not worth it anymore.
