LPDDR5 is a fast, power-saving type of RAM used in phones, tablets and thin laptops.

LPDDR5 is a type of RAM made for battery-powered devices. LPDDR stands for Low-Power Double Data Rate, and the 5 marks the fifth generation. It is an open standard from the JEDEC industry body, so many chip makers follow it. It came after LPDDR4X and before LPDDR5X.
How it works
RAM holds the apps and data a processor is using right now. LPDDR chips are designed to use little power, and they are often packed close to the processor to save space and energy. LPDDR5 moves data faster than LPDDR4X. It can also lower its speed and voltage when the device is idle, which saves battery.
What the numbers mean
- The number is the generation. A higher number is a newer design.
- Speed is quoted in megabits per second for each data pin. LPDDR4X is rated up to 4,266 and LPDDR5 up to 6,400.
- LPDDR5X is a later, faster version of the same generation and has its own entry.
What it does not promise
Faster memory does not decide by itself how quick a device feels. The processor, the storage and the software matter just as much. LPDDR5 also says nothing about how much RAM a device has, because that is a separate figure in gigabytes. The memory is normally soldered in, so it cannot be upgraded later.
