All those crazy rumors of devices launching in 2015 with 4GB of RAM onboard suddenly don’t seem all that crazy with this latest news from Samsung. That news being that the South Korean giant will be delivering 4GB LPDDR4 packages in early 2015. Of course, that doesn’t mean that every device in 2015 will have 4GB of RAM, far from it. Rather, this is Samsung’s way of saying that they have the capability to do so, but the more exciting part of Samsung’s news today is that LPDDR4 chips have now entered mass production. You might be wondering what that might mean for the next generation of smartphones and tablets, and so I’ll do my best to shed some light on things.
LPDDR is similar to the DDR RAM that you find in laptops and computers, but it’s much, much smaller and therefore designed for mobile applications. LPDDR3 RAM is the standard that the vast majority of high-end smartphones and tablets are using for their memory. LPDDR4 RAM is the next generation of mobile memory and is said to be as much as two-times faster than DDR3 RAM found in laptops and games consoles like the Xbox One. That’s a bold claim from Samsung, but with an I/O rate of 3,200 mbps the new 8 Gigabit modules are super-fast and will have a big impact on smartphone performance. Not just that, but as a result of the new 20 nanometer manufacturing process Samsung can now create 4GB modules for future devices.
LPDDR4 RAM is going to make a difference when it comes to recording high-quality video, taking lots of photos at once and overall performance. More than just an all-round speed boost though is the promise of better battery life. The new LPDDR4 modules use as little as 1.1V and when compared to a 2GB LPDDR3 module, a 2GB LPDDR4 module could use up to 40% less power, which should benefit us as all.
