DDR2 vs. DDR: Revenge Gained. Page 11

DDR2 memory tests, which we have performed earlier, showed that its higher latency is exactly the reason why it gets defeated by the regular DDR SDRAM. However, now the situation is changing. The leading memory manufacturers offer DDR2 modules with improved timings, which make DDR2 look completely different from what it used to be.
Let’s now see how the choice of the memory modules can affect the performance of the system in general.
The diagrams show that the speed of real applications varies depending on the particular memory module. OCZ’s PC2 4200 Enhanced Bandwidth Platinum sticks boast the highest performance again, while the OCZ PC2 4300 loses in almost all the tests. The modules from PQI, GeIL and Corsair have similar speeds, although different timings are written into the SPD units of these modules.
