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 unbuffered bandwidth scores.
Results: On Sandra Xi SP4 DDR3 at 1350MHz with CL9 timings scored in at 8,183MB/Sec versus the 9095 MB/Sec on the 1800MHz CL7 kit, which is a 912MB/Sec increase in bandwidth or an 11% increase. By setting the timings even tighter on the 1800MHz CL7 kit we were able to increase the bandwidth another 240MB/Sec, which is a 2.6% boost in performance.
Sisoft Sandra XII just came out this week and it was included, so our readers would be able to compare their modules to this kit if they are using the just released version of Sandra! With Sandra XII you can now easily compare the performance of the tested device with its speed and its (published) power (TDP)! Sandra XII also has SSE4 (Intel) and SSE4A (AMD) benchmark code-paths, which is great for those of you testing next-generation AMD & Intel chips.
Results: Sandra XII showed higher bandwidths than Sandra Xi SP4, but the results remained the same.
