DDR5 & LPDDR5X
Technology
Memory
The system memory feeding CPUs — and, via Grace, the GPUs too.
You're looking at a technology record: a building block of AI hardware — what it does, who makes it, and which chips and systems use it.
Conventional DDR5 DIMMs serve host CPUs, while low-power LPDDR5X soldered next to Arm CPUs (Grace, Vera) gives superchips hundreds of gigabytes of cost-efficient capacity — the second memory tier of modern AI nodes.
