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]
