Samsung’s first-generation development offers a rate of 8.5 Gbps, which means 32 GB / s of bandwidth per channel. At the same time, dissipation, or consumption in common parlance, also decreased, by about 20 percent compared to LPDDR5. According to the South Korean manufacturer, thanks to the 14-nanometer bandwidth and advanced encapsulation procedures, up to 32 chips can fit in a single chip, resulting in a capacity of 64 gigabytes.
LPDDR5X is based on LPDDR5, which has been introduced for a good three years and has been widely used ever since. In addition to the effective clock, the main difference is the number of memory banks per channel: while the LPDDR5 can have a value of 8 or 16, the LPDDR5X has a fixed number of 16 banks, maximizing the transfer rate.
Another important development of LPDDR5X is to reduce dissipation. LPDDR5 has taken a big step forward, as the VDDQ I / O voltage has dropped significantly from 1.1 to 0.6 volts, nearly halving the highly energy-efficient LPDDR4X. The default core voltage remained at 1.1 volts, but manufacturers can already go below that. Samsung has been able to achieve a 20 percent reduction by mitigating this, although there is no public data yet on exactly how far the LPDDR5X goes below the 1.1-volt threshold.
Thanks to the LPDDR5X, the battery life of mobile devices (smartphone, tablet, etc.) will be able to increase further, while their computing power will also move in a positive direction. However, we still have to wait another year for all this, because according to the current situation, products equipped with LPDDR5X memory will be available in 2023 at the earliest.
