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 AMD Ryzen 7 1700X isn't due for release until next week but two of our users has already submitted benchmarks. Comparing the quad and single core scores from our samples shows a relative 4.3% boost on the single core score so it’s possible that turbo wasn’t fully engaged (12% turbo boost expected). These preliminary results are seriously impressive as they put Zen’s IPC between 0% and 9% below Intel’s Kaby Lake. Even in the worst case scenario these results are still impressive. Comparing Intel’s $1,000 6900K and the 1700X shows that AMD delivers comparable performance for half the price! A shake-up of the CPU market will unfold as Zen rolls out. If Ryzen CPUs can overclock to 4.6+ GHz they will likely dominate the entire market putting a very welcome end to the monotonous tick-tock of recent years. [Feb '17 CPUPro]
