The Intel Pentium G3240 is a budget dual-core, twin threaded processor. It was released in Q2 2014 and with a base frequency of 3.1 GHz it scores a reasonable 78 for effective speed. The G3240 is quick enough to run most basic applications without any issues and it’s very reasonably priced for its performance. The integrated HD Graphics are fine for general desktop use but not for 3D gaming. The G3258 has a base frequency just 100 MHz faster than the G3240, but can be unlocked to realise speeds up to 4.3 GHz using just the stock cooler. Comparing the G3258 and G3240 shows that when the G3258 is overclocked it offers 48% more performance for just a 13% price premium. [Nov '14 CPUPro]

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]
