Samsung on Thursday announced a major breakthrough in the future of smartphones: mass production has begun on the industry’s first 12GB LPDDR5 mobile DRAM chip, so it should start showing up in smartphones pretty soon. But don't get your hopes up about it showing up on the Galaxy Note 10's spec sheet next month.
As Samsung explains in its press release, the 10nm LPDDR5 chip (Lower Power Double Data Rate) has been "optimized for enabling 5G and AI features in future smartphones." That mainly boils down to speed. The new chips have a data rate of 5,500MB/s, about 1.3 times faster than the 4,266MB/s LPDDR4X DRAM used in the Galaxy S10 5G and the 20nm LPDDR4 in the Galaxy S10+. That's not quite as big of a leap as the 2x increase from LPDDR3 to LPDDR4 (2,133MB/s to 4,266MB/s) but it's still significant.
