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]

The Core i5-3570K Ivy Bridge processor is one of Intel's best performers to date. In terms of real world performance this processor offers far more than most users are likely to ever need. Scoring 2012 points on the PassMark Single Thread benchmark, the 3570K is within a few percent of the fastest processors currently available and at 77 watts TDP it's no energy hog either. The server orientated GeekBench and PassMark scores of 13920 and 7144 put the 3570K at just over the 50% marker in terms of total processing capacity compared to the other processors in the group test. For server based workloads more performance is available from the Core i7 range of processors but for typical consumer use this processor is already far more powerful than it needs to be. [May '13 CPUPro]
