Sisoft Sandra XI SP4 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 averaged results of the buffered and unbuffered bandwidth scores.
Results: On Sandra Xi SP4 DDR3 at 1333MHz nearly topped 7,000 MB/Sec on the Kingston HyperX kit, but just didn’t have enough speed. The spread between the fastest and slowest kit was just 194MB/Sec, which is only 2.7% difference in performance.
WinRAR has a multithreaded version of the RAR compression algorithm, which improves the compression speed on computers with several CPU, dual core CPU and processors with hyperthreading technology. Multithreading is enabled by default, but you can disable it in “General” part of “Settings” dialog.
Results: The WinRAR 3.70 benchmarking results graphed out nicely and showed that the CL9 and CL8 modules were a bit slower than the Kingston HyperX and OCZ Platinum CL7 memory kits when all were run at 1333MHz. Kingston’s HyperX kit pulled out in the lead here and beat the Corsair XMS3 1333MHz DHX memory kit by 89KB/Se, which at 6% is a significant difference.
