When buying RAM, you can identify the speed by its name, for example, Crucial Ballistix 16GB DDR4-3200. In comparison, DDR4 RAM ranges from 2,133 to 3,200 MT / s, not to mention the fastest kits available via XMP and overclocking. DDR3 specifications range from 800 to 2,133 MT / s (million transfers per second). While that might not sound like much, it’s about a 20 percent improvement in efficiency between these two generations.įor most home users, the voltage difference ultimately results in lower power consumption and heat generation, which is especially important in laptops, where it can affect battery life.ĭDR4 is not only more energy efficient, it is also much faster. Differences between DDR3 and DDR4ĭDR4 tends to run at 1.2V by default, while DDR3 runs at 1.5V. Neither is compatible with the newer DDR5 memory. With major changes to their physical design, specifications, and features, motherboards with DDR4 slots cannot use DDR3 RAM and DDR4 cannot be placed in a DDR3 slot. What are the main differences between DDR3 and DDR4? Here we will explain it to you. However, in 2014, DDR4 was released to the public and has since become the standard. During that time, it set the standard in conventional notebook and desktop computers for many years. DDR3 memory had a long life on the market after its launch in 2007.
