We observe a similar picture in games. DDR3-1600 results look impressive only against the background of a system with DDR2-800 SDRAM. In this case the performance advantage lies between 5-10%. If we look at the performance difference between systems with DDR2-1067 and DDR3-1600, the advantage of faster memory will no longer be that evident.
We can draw the same conclusions basing on the results obtained in application tests. It is evident that DDR2-800 SDRAM is not the best choice for an LGA775 system working at 400MHz FSB. Using DDR2-1067 memory is quite justified in this case, and the advantage of DDR3-1600 will only be a slight performance improvement.
So, it turns out that DDR3-1600 is not a highly justified choice even for systems running at 400MHz FSB. The performance improvement it provides compared to DDR2-1067 SDRAM is insignificant, while the price difference between them is quite serious. Nevertheless, we don’t give up hope to find suitable application for the DDR3-1600 SDRAM, so let’s see what happens during more serious system overclocking.
