What is DDR4 RAM ?

DDR4 SDRAM is the abbreviation for “double data rate fourth generation synchronous dynamic random-access memory,” the latest variant of memory in computing. DDR4 is able to achieve higher speed and efficiency thanks to increased transfer rates and decreased voltage. The last dynamic random-access memory update, DDR3, came out in 2007, but developers began working on DDR4 back in 2005. Samsung manufactured the first DDR4 memory console in 2011 and this technology is expected to hit the consumer market sometime in 2014. External hardware receives more hype, but this new memory technology is one example of the internal developments that enable computing advancements.

DDR4 chips are expected to support transfer rates between 2133 MT/s (million transfers per second) and 4266 MT/s. By comparison, DDR3 technology supports only up to 800 to 2133 MT/s. This significant memory transfer boost will enable hardware developers to produce DDR4 chips with more powerful processors and more capable devices. This new memory also uses less power -- 1.2 Volts compared to 1.65 Volts of DDR3 chips. This reduced power consumption should lead to better battery life in portable devices such as phones and tablets. DDR4 doesn’t fundamentally change the way memory operates, but it features a new command signal to indicate the active command. The /ACT command consolidates the previous process, which demanded three separate commands when an active command is in use.

DO you need DDR4 RAM Memory?

You can't buy DDR4 RAM memory today, and your existing hardware wouldn't be able to use it if you could . But it's a safe bet that it will be expensive when it dois come to market. Mike Howard, memory analyst at there search firm IHS, said he expects DDR4 memory to launch later this year at prices 40to 50 precent higher that DDR3 RAM memory . So if you were to by 16GB of DDR3 memory at the average price of $140 , he same amount of DDR4 Ram memory would set you back around $210.

"As we go forward, DDR4 will get more engineering resources,” said Howard. “2016 is when we will see price parity with DDR3. Then it will get cheaper as more people put resources into it.”

That’s not to say DDR4 RAM will be a waste of money. It’s just that in its early days, it won’t deliver significant benefits to anyone beyond the earliest of adopters.
