The AMD FX-4100 is an inexpensive entry level quad-core processor. It was released in Q4 of 2011 and at the time was AMD’s budget chip on its latest Bulldozer architecture. Its base clock speed of 3.6 GHz boosts to 3.8 GHz in turbo mode and with appropriate cooling can be over-clocked to speeds of 4.9 GHz. Even though these numbers appear impressive, the real world effective speed only averages 59. This should be fine for general computing and even gaming when coupled with an appropriate GPU. It’s the FX-4100’s single-core performance which lets it down when compared to similarly priced Intel processors such as the Core i3-3225. Since the majority of daily computing relies single core performance typical desktop users will find better value elsewhere. [Nov '14 CPUPro]


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]
