Samsung recently announced its latest technological marvel i.e. very first LPDDR5 DRAM. In a press release, it was announced that the company will begin mass production of these new sticks. They will be considerably faster and much more power efficient than the current LPDDR4. Though Samsung didn’t announce a launch date or a schedule as to by when these will start coming into mobile phones, I expect them to be in their flagship lineup of 2019.
If this happens, these flagships will be up to 150 per cent faster and about 30 per cent more power efficient than today’s flagships. Currently, LPDDR4 is used in all the flagships which boast of a maximum data transfer rate of 4,266 MB/s. LPDDR5 is claimed to have data transfer rate of 6,400 MB/s significantly higher than LPDDR4.
The secret to LPDDR5 chips being so much more efficient than their predecessor LPDDR4 chips is the difference in their construction. While in LPDDR4 nodes have a distance of 20 nanometers between them LPDDR5 reduces it to 10 nanometers. Lesser the distance between these nodes, less time and energy it would take to transfer information between them.
There are a couple other features too included in LPDDR5 chips such as deep sleep mode, which is similar to the “idle mode” on LPDDR4 chips. According to Samsung, deep sleep mode will be 50 per cent more efficient than the idle mode on LPDDR4 chips.
With the increased power efficiency and reduced processing time, the flagships in near future should be able to handle heavy tasks easily. We might just see tremendous increase in apps with complex AI and machine learning.
There is no certainty which phones next year will be using LPDDR 5 chips, but you can place a good bet on flagships like Samsung Galaxy S10 or Samsung Galaxy Note 10. Samsung plans to release these chips in lieu of the global demand.
