Samsung introduced its LPDDR5 RAM, but there’s still
room in the market for the older standard – LPDDR4X. Today the company unveils
the second generation of 4X chips, which deliver 4,266 megabits per second.
These are 16 gigabit chips – that’s 2GB per chip,
compared to 1GB for the LPDDR5. This means only four of them are needed for the
8GB package that Samsung created, which saves on price (LPDDR5 needs eight
chips for that capacity).
Also, second-gen LPDDR4X uses 10% less power than
the first-gen and the new 8GB package and is 20% thinner than one using the
older 4X chips. This is thanks to an improved “10nm class” process (the actual
node is somewhere between 10nm and 19nm).
The new RAM chips will be seen in phones launching
in the first half of 2019. Samsung has also put together 4GB and 6GB packages,
so makers have plenty of choice.
