800 MHz means the RAM has a speed of 800 million operations per second. The frequency of DDR3 starts at 800 MHz and ends at 2133 MHz. On only one or two systems, this doesn’t make much of a difference but on a server side, if there are hundreds of servers running the same hardware, upgrading the RAM to DDR4 will make quite a visible difference in power usage of the whole environment. This means that DDR4 RAM will use a lot less power as compared to DDR3. Voltage and power usageĭDR3 operates on 1.5V (1.35V on power saving mode) while DDR4 operates on 1.2V. Let’s go through the comparison bit by bit and then conclude at the end.
One interesting thing to note here is that DDR4 does not give a performance boost for Gaming PCs. It is much more expensive than DDR3, almost double in price at the time of this writing. When we look at the market share of both types of RAMs, DDR4 is not backward compatible and is only available for Intel’s X99 platform. But we will try to compare the functionality of both RAM types in easy and plain language so that everyone can understand the core differences between the two and decide whether to upgrade or not. DDR3 and DDR4 are types of RAMs that can’t be compared easily because both need different kinds of hardware to operate. DDR4 is the latest fourth generation RAM technology after DDR3.
