Memory type matters a lot during image editing in a popular graphics application. Even with the common DDR3-1333 we could get our system to run faster than Socket AM2+ platform with DDR2-1067 SDRAM.
Calculations in Excel and Mathematica are also working faster on a new platform. The advantage of our Socket AM3 system with DDR3-1600 over a Socket AM2+ configuration with DDR2-1067 SDRAM is almost 3%.
The archiving utility speeds up on about the same scale.
Summing up I can say that Socket AM3 platform with Phenom II X4 processor accelerates typical tasks by about 2-3%. Taking into account the today’s price difference between DDR2 and DDR3 memory modules, this improvement seems rally insignificant. However, as DDR3 SDRAM continues to become more affordable, Socket AM3 platform will become more and more promising.
