- Capacities
- 16 Gb
Overview
16 Gb GDDR7 using PAM3 signaling at 32 Gbps and above, for next-generation graphics cards and AI inference accelerators.
GDDR7 moves graphics DRAM to PAM3 signaling, reaching 32 Gbps per pin and above — over 1.5 times GDDR6 bandwidth — while improving power efficiency per bit. SK hynix supplies 16 Gb densities with roadmap grades toward 40 Gbps for bandwidth-hungry GPU and accelerator designs.
Beyond gaming graphics, GDDR7 serves AI inference cards and network processors that need high bandwidth without HBM's packaging cost. A 32-bit-wide device at 32 Gbps delivers 128 GB/s, letting an eight-device board exceed 1 TB/s of memory bandwidth.
