Difference Between DDR3 vs DDR4 RAM

DDR3 and DDR4 are both types of RAM, or random access memory, used in computers.The main differences between DDR3 and DDR4 are:

1. Speed: DDR4 is faster than DDR3. DDR4 operates at higher frequencies, which means it can transfer data more quickly. DDR4 typically operates at speeds ranging from 2133 MHz to 4266 MHz, while DDR3 operates at speeds ranging from 800 MHz to 2133 MHz.
2. Voltage: DDR4 uses less power than DDR3. DDR4 operates at a voltage of 1.2V, while DDR3 operates at a voltage of 1.5V or 1.35V. The lower voltage of DDR4 makes it more energy-efficient.
3. Capacity: DDR4 can support more memory per module than DDR3. DDR4 can support up to 16GB per module, while DDR3 is limited to 8GB per module.
4. Compatibility: DDR3 and DDR4 are not compatible with each other. DDR4 uses a different type of slot and a different number of pins than DDR3, so they cannot be used interchangeably.

Overall, DDR4 is faster,more energy-efficient, and can support more memory per module than DDR3.However, DDR4 is also more expensive than DDR3, so the choice between the two will depend on your budget and the specifications of your computer.
