DDR2 is slower than DDR3 due to their difference in bandwidth. DDR3 has a higher bandwidth hence can transfer data at higher speeds than DDR2.
they are different ram generations. DDR2 is the older and slower version of DDR3. DDR2 is about 800 MHz max. and DDR3 is about 1333 MHz minimum
It is not very noticeable if you upgrade your memory on your computer.
No, DDR2 is quite slower than DDR3. DDR4 was released very recently. DDR4 is currently the fasted SDRAM available.
DDR3 uses lower voltage
The difference between the memory of the DDR2 RAM and the DDR3 RAM are the capacity that they can hold the DDR3 RAM is more powerful than the DDR2 RAM.

DDR3 uses 1.5V; DDR2 uses either 1.8V or 2.5V

There are 240 pins on DDR2 and DDR3.
DDR3 runs at higher clocks and lower voltages due to a more complex 90nm manufacturing process than DDR2 Ram. So therefore, DDR3's main difference in comparison to DDR2 is better power usage and higher clock speeds.
