LPDDR5X

LPDDR5X, short for low-power double data rate 5X, is a type of dynamic random access memory (DRAM) built for high bandwidth at low power. It is a JEDEC standard that evolved from LPDDR5, and it appears in phones, thin laptops and desktop AI computers. The chips are normally soldered to the board, so capacity is fixed when the system is built. That trades upgradability for power efficiency.

Micron's top LPDDR5X speed grade is 10.7 Gbps per pin. NVIDIA's DGX Spark pairs its GB10 Grace Blackwell Superchip with 128 GB of LPDDR5X on a 256-bit interface, for 273 GB/s. NVIDIA's Vera server CPU draws up to 1.2 TB/s from LPDDR5X at less than half the memory power of traditional DDR configurations. Vera also takes SOCAMM, or small outline compression-attached memory modules. These replace soldered memory with detachable modules and hold up to 1.5 TB per socket.

Buy a soldered LPDDR5X system such as DGX Spark with the most memory it will ever need, since none can be added later. If capacity must grow after purchase, choose a DDR5 DIMM platform or a SOCAMM server instead.
