Some of the most difficult to answer questions in the enthusiast and high-end gaming PC world have to do with RAM, and more specifically with RAM clock speeds, latency, and timings. What differences do all of these make when it comes to better performance and higher frame rates in games? Typically, the answer is that they do very little when it comes to games. AMD has sought to change that answer with the release of their Richland series APUs, which are designed to take even more advantage of RAM speeds and support up to 2133MHz clock speeds. Intel's Haswell now supports speeds of up to 1600MHz. Now that more is being done to increase the performance gain from higher RAM speeds, let's take a look at the results. Here at Benchmark Reviews, we have a couple of new high-speed RAM kits to review. In this article, we will be taking a look at the Kingston HyperX 8GBx2 DDR3-2133 KHX21C11T3K2/16X kit.
