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]
