Fermi through Maxwell: 5 Generations of GeForce Graphics Compared

When new GPUs arrive we usually compare them to their predecessor but rarely go back more than one generation. Today we'll be testing six cards covering three key Nvidia architectures: Fermi (the GTX 480 and GTX 580), Kepler (theGTX 680 and GTX 780) and Maxwell (the GTX 980). Many of you who haven't upgraded GPUs in over a year may be pleased to see how performance scales and what to expect in modern games.

AMD FX-8350 & FX-6300 Overclocked: Real world power to performance testing

Intel has been beating AMD on every front but price for a couple of generations now as the Bulldozer microarchitecture and its descendants have had an unpleasant uphill climb. Power consumption, performance per clock, it all takes its toll. However, we took a couple of AMD’s most popular chips for a test drive and found that things aren’t anywhere near as bad as benchmarks might lead you to believe. Quite the opposite, actually.

Enthusiast Territory: The most memorable overclocking-friendly CPUs

Enthusiasts have been pushing the limits of silicon for as long as microprocessors have existed. Early overclocking endeavors involved soldering and replacing crystal clock oscillators, but evolving standards brought options for changing system bus speeds, while some of the most daring would gain boosts through hard modding. These are but a few of the landmark processors revered for their overclocking prowess.

Quantified: How high temperatures, cooling affect CPU performance

Older CPUs would simply fail if they started to overheat, but modern CPUs adjust their frequency based on temperature (among other things) to prevent a dramatic failure. Because of this, it stands to reason that once you reach certain temps, you will no longer be getting the maximum performance from your CPU because it will be busy protecting itself. But what is that temperature? And do you really need a high-end liquid-cooled system to get peak performance?
