Tencent Technology News, July 19 news, according to foreign media reports, as wireless networks and mobile CPU faster and faster, the speed of RAM used in portable devices may actually become a performance bottleneck, thus preventing them from processing data at peak speed. Samsung, which is doing its best to improve the performance of the next generation of mobile devices, today announced that it has begun mass production of 12 Gigabit LPDDR5 DRAM chips aimed at

Samsung's move is important, especially as it plays an important role in providing memory to other mobile device manufacturers. Samsung's DRAM can be found not only on its Galaxy phones and tablets, but also on Apple's iPhone and its rival Android devices. Therefore, the performance improvement of Samsung memory chips will affect the flagship products of many companies, and foreshadows the general direction of all companies in the near future.

The new LPDDR5 chip provides a data rate of 5,500 Mbps, about 30% higher than today's LPDDR4X (4,266 Mbps) used in high-end smartphones, including the first 5G smartphones based on Qualcomm Mbps 855 processors. Samsung said that the new DRAM will support ultra-high definition video recording and AI-driven machine learning, greatly improving the battery life of the device, compared with the previous DRAM, power consumption reduced by 30%.

The higher speed of LPDDR5 will depend on the next generation of mobile processors, which can transmit 44GB of data per second, enough to store 12 1080p-quality movies. To achieve this speed, Samsung bundled eight 12 Gigabit LPDDR5 chips as 12 GB chip modules. Samsung said the process would begin later this month, following the start of production of 6GB chip modules last month. The company plans to launch 16 Gigabit LPDDR5 chips next year.

In other words, users of next-generation mobile devices should not only see a dramatic increase in speed and battery life, but also a dramatic jump in memory. Today's top smartphones usually have less than 8GB of RAM, and in some cases, for example, the iPhone XR and the iPhone XS only have 3GB or 4GB. In the future, 5G mobile phones with Samsung LPDDR5 RAM will usually be equipped with 6GB or 12GB RAM configuration, followed by 8GB and 16GB configuration. (Tencent Technology Revision/Jinlu)
