The tests in real applications are critical to the memory subsystem performance, however, they show quite familiar situation with no superiority of DDR3 SDRAM over the previous generation memory type. I would only like to stress the fact that you shouldn’t dramatize the effect of the memory speed on the overall platform performance. The performance difference between the platforms using the slowest DDR3-800 and the fastest DDR3-1333 SDRAM is 5% at the most in computational tasks and office applications and maximum 10% in games.

The benchmark built into WinRAR archiving tool gives DDR3 SDRAM a break. Here we can finally see the advantages of increased DDR3-1333 SDRAM bandwidth. However, there are no real applications that would react the same way to increased bandwidth.
