Everest 1.1 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 to give a fairly accurate look of true memory performance.
Sisoft Sandra 2004 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.
ScienceMark 2.0 is different from other benchmarks, in a sense the benchmark tests a series of different memory bandwidth algorithms. To top it all off the assembly source for these copy routines is available online to help assure the benchmark is not biased towards any one platform in particular.
Results: It’s fairly obvious that the 533MHz DDR2 memory found on our Intel 560 test system performed on par with 400MHz DDR1 memory. Yes, in some areas such as Everest READ testing DDR2 pulled ahead, but not enough to make us jump up and down. One of the reasons that improvements to the memory bus seem lackluster to us is because recent Intel and AMD processors have not been "starved" when it comes to memory bandwidth. Meaning improvements found here more than likely wont translate to real world performance gains, but more bandwidth can’t technically hurt your system!
