In the memory market, currently DDR2 and DDR3 are all exist, but now DDR3 memory price is higher than DDR2 memory, many users are more confused, what’s the comparative advantage of DDR2 and DDR3 memory?
? Frequency: DDR3 can run in the 800MHz to 2000MHz (also higher), while the DDR2 is running under 533MHz to 1066MHz. In general, DDR3 is twice the frequency of DDR2, through the cut in half the time to read and write to bring to the system to improve operational performance.
? Power: DDR3 than DDR2 can save 16% of the electricity, because a new generation of DDR3 is 1.5V voltage, while the DDR2 is at 1.8V to work, so you can make up for excess generated by the high operating frequency power consumption, while reducing the energy consumption can extend the service life of components.
? Technology: DDR3 Memory Bank increased to 8, more than doubling the DDR2. Therefore, DDR2 compared to 50% of the pre-reading will improve the efficiency, is twice the DDR2 standard.
