With the improvements on the DDR4 comes an increase in its price. This is unlike the DDR3, which performs both a self-refresh and an auto-refresh on its content. The DDR4 memory performs a self-refresh to refresh its content. This makes it the most responsive DDR RAM on the market.Īnother improvement on the DDR4 is the reduced power consumption. It also has an excellent heat spreader that allows it to operate for long hours without overheating. The DDR4-2400 is the smallest, while the DDR4-4400 has the highest speed and bandwidth.ĭDR4 is optimized for gamers, hence the elevated speed and bandwidth. Like the DDR3, DDR4 is offered with a range of specs. It has a larger capacity than its predecessors, the DDR, DDR2, and DDR3. What is DDR4?ĭDR4 is the fourth generation of DDR RAM to be introduced on the market.
This is the lowest speed DDR3, and the highest in the DRR3-12800, with 1600 million per second bandwidth at 12800 MBps. DDR3-800 indicates that it has an 800 million per second bandwidth at 6400 MBps. Essentially, if you have a computer with a DDR3, it will process files twice as fast as a DDR2 equipped machine.ĭDR3 memory chips come in different specs depending on their speed. The DDR2 has a RAM speed of 3200 megabytes per second (MBps) while DDR3 can achieve 6400 MBps. The DDR3 uses about 30% less power and is two-times faster than its predecessor, the DDR2.
