The MSI X58 Pro-E delivered particularly good bandwidth in SiSoftware Sandra 2009, reaching 22GB/s when paired with DDR3-1333 memory. This made the X58 Pro-E ~2GB/s faster than the ASUS P6T Deluxe in our testing. Interestingly overclocking the Core i7 processor to 4GHz using the X58 Pro-E only had a slight impact on the SiSoft memory bandwidth performance.
The EVEREST Ultimate Edition results were much the same, though here we see that the ASUS P6T Deluxe and MSI X58 Pro-E produced roughly the same write performance. The read performance did favor the X58 Pro-E by just over 1GB/s and this is likely what skewed the SiSoftware results.
