We should pay special attention to the systems performance in games. As you know, games are extremely sensitive to memory subsystem characteristics. To ensure an even more evident effect, we ran all tests in low resolutions, where the graphics subsystem has minimal influence on the frame-per-second rate.
True, games turn out to be these particular tasks where high bandwidth of DDR3 SDRAM affects the performance. Honestly, the performance advantage demonstrated by DDR3-1333 is not too impressive, however, you can still notice it with a naked eye. Nevertheless, DDR3-1333 with CAS Latency 9 can’t outperform DDR2-1067, and DDR3-1333 with 7-7-7-20 timings is barely 0.5% faster than DDR2-1067.
In addition to the results discussed above we also measured the testbeds performance in a number of other applications creating significant system load:
In fact, there is nothing surprising here. All the conclusions made before prove absolutely correct during archiving, video encoding, rendering and chess gameplay. The archiving utility turned out the most dependent on the memory subsystem performance; however, even in this case DDR3-1333 SDRAM was no more than 3% faster than the platform with fast DDR2-1067.
The conclusion is evident: using DDR3-1333 SDRAM in contemporary LGA775 platforms doesn’t make any sense considering how expensive it is. Therefore, today we are not going to talk about 4GB DDR3-1333 kits. Instead we are going to discuss DDR3-1600 SDRAM.
