Samsung announced that it has developed the industry’s first LPDDR5X DRAM for smartphones and other applications. Compared to the LPDDR5 standard, the new chips bring higher speeds and we’ll see them in action on a few 2022 flagship phones.

The LPDDR5X will deliver around 30 percent more performance than its predecessor, boosting it to 8.5 Gbps. While this is a good increase, it falls short when compared to the staggering four-fold increase in capacity brought by the LPDDR5X, which is stated as 64GB. Samsung says this will likely be possible with 14nm 16Gb (2GB) LPDDR5X chips, which will likely be developed using some form of UFS-based multi-chip package (uMCP) technology. Currently, the company uses a UFS 3.1-based solution for LPDDR5. Therefore, it is possible to use the new generation UFS for LPDDR5X.

This means that devices using LPDDR5 on gaming phones like the ASUS ROG Phone 5, which currently reaches 18GB, can carry 64GB of memory. On the other hand, it is also possible that 64GB capacities are reserved only for laptops or other high-end devices and applications. That’s because 64GB will probably still be too much for even the next generation’s heaviest multitasking and gaming smartphones. Already, Samsung expresses this with the following words:

“Our LPDDR5X will extend the use of high-performance, low-power memory beyond smartphones and bring new capabilities to AI-based edge applications such as servers and even cars. ”

Besides speed and capacity improvements, the LPDDR5X also promises a 20 percent power efficiency increase compared to the LPDDR5 standard. Finally, it should be noted that the mass production of the new LPDDR5X chips will begin towards the end of the year.
