ISSUE 66 • ANDROID ADVISOR 11NEWSbeen “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.
With the new process, Samsung has combined
eight 12Gb LPDDR5 RAM chips in a single 12GB
packageforuseinmobiledevices.Forthecurrent‑
generation LPDDR4X 12GB package, Samsung used
six 16GB chips.
That means future phones will theoretically be
able to transfer 44GB of data in about a second. The
new chip also uses up to 30 percent less power than
its predecessor, Samsung says, by “integrating a new
circuitdesignwithenhancedclocking,trainingand
low‑power feature that ensures stable performance
even when operating at a blazingly fast speed”.
