Firstly, it has a maximum data rate of up to 6400Mbps at 1.1V, which Samsung claims to be about 1.5 times faster than the current LPDDR4X memory standard. This increased transfer rate enables the LPDDR5 chip to send 51.2 GB of data, which is equal to 14 full-HD video files, in one second. The performance advancement was made possible through several architectural enhancements. It's also said to make use of a "highly advanced, speed-optimized circuit architecture that verifies and ensures the chip's ultra-high-seed performance".

Additionally, these 10nm LPDDR5 RAM chips have been engineered to lower its voltage in accordance with the operating speed of the corresponding application processor, when in active mode.

Samsung has announced its first LPDDR5 memory chip. Additionally, it doesn't overwrite cells with "0" values. The new chip sets the stage for the transition to LPDDR5 which is more capable for AI-powered mobile applications. Samsung notes that the deep sleep mode cuts the power usage to approximately half the "idle mode" of the current LPDDR4X DRAM.

Alisson Becker now knows just how serious Liverpool are about bringing him to Anfield this summer. Jurgen Klopp has insisted that he is ready to stick with Loris Karius ahead of the new campaign.

The latest addition to Samsung's premium DRAM lineup joins the 10nm class 16GB GDDR6 DRAM which has been in volume production since December 2017. We should expect to see Samsung's new LPDDR5 memory inside of smartphones in the coming months, and then for years to come with next-gen smartphones announced in 2019 and beyond.

Based on its industry-leading bandwidth and power efficiency, the LPDDR5 will be able to power AI and machine learning applications, and will be UHD-compatible for mobile devices worldwide. While Samsung didn't spell out when LPDDR5 chips would be ready to hit the market, production will coincide with demand from global customers.

DDR5 as a standard is still a little way off yet, and LPDDR5 is really a much bigger deal for mobile devices than their desktop counterparts.
