SiSoftware Sandra is a 32- and 64-bit client/server Windows system analyzer that includes benchmarking, testing and listing modules. It tries to go beyond other utilities to show you more of what is really going on under the hood so you draw comparisons at both a high and low-level in a single product. You can get information about the CPU, GPGPU, chipset, video adapter (GPU), ports, printers, sound card, memory, network, Windows internals even .NET and Java.
We would caution you not to jump to conclusions, as RAM is as specific as designer clothing and you can only compare kits rated to run at the same speed. Both Kingston kits on the charts run at 3000MHz and CL 15-16-16 or CL 15-17-17 and are fairly comparable. You can’t get an apples to apples comparison with a kit rated to run at 2666MHz when comparing it to a 3000MHz kit. RAM kits are like cars; you pay for how fast you want to go.
Our Corsairs Vengeance LED 32GB 2666MHz Kit kit gave us 31.5MB/s Integer and 31.33MB/s Float.
