Samsung’s LPDDR5 8 GB DRAM Will Drastically Improve Your Phone Speed and Performance


Samsung held a press release today to unveil its latest advancement in mobile technology: the industry’s first 10-nanometer class 8-GB LPDDR5 DRAM.

You may not know what that means. In a nutshell, it means that the next generation of flagship smartphones will be 150 percent faster and consume up to 30 percent less power than today’s flagships.

At this time, the industry standard DRAM used in flagship devices is LPDDR4 which was first launched in 2014.

LPDDR4 was a significant leap over the previous industry standard, LPDDR3. It looks like the move from LPDDR4 to LPDDR5 will be no different, with Samsung claiming a data rate of up to 6,400 megabits per second, which completely trounces LPDDR4’s maximum of 4,266Mb/s.How fast is that? Imagine sending over 51GB of data in one second. That’s how fast.

The point of focus is the fact that the new LPDDR5 chips use 10-nanometer construction, which is much more efficient than the 20nm construction in LPDDR4 chips. The nanometer designation tells us how far apart each node is on a chip: the closer the nodes are, the less energy it takes to transfer information from one node to another, and the less time it takes to move that info. That efficiency results in faster, less-power-hungry smartphones.

Additionally, LPDDR5 chips will offer a “deep sleep mode,” which cuts the power usage when your phone is idle. Samsung claims this will be 50 percent more efficient than the current “idle mode” featured on LPDDR4 chips.

With all this power, speed, and efficiency, the next generation of flagship smartphones will be able to handle heavy tasks with ease, such as AI and machine learning applications, and ultra-high definition (UHD) video playback.

Samsung doesn’t say which future devices will use LPDDR5 DRAM, but it’s a guess that a 2019 Samsung flagship like the Samsung Galaxy S10 or Samsung Galaxy Note 10 will run on LPDDR5. According to Samsung, it will begin mass production “in line with the demands of global customers.”
