Sisoft Sandra 2005 is designed to test the theoretical power of a complete system and individual components. The numbers taken though are, again, purely theoretical and may not represent real world performance. Higher numbers represent better performance in memory bandwidth. The chart was based off of the buffered bandwidth scores.
Everst 2.20 is a professional system information, diagnostics and benchmarking program for Win32 platforms. It extracts details of all components of the PC. It also tests the actual read and write speeds of your memory giving a fairly accurate look of true memory performance.
