GDDR7
7th-gen graphics DDR memory.
GDDR7 is the memory standard on RTX 50-series and RDNA 5 GPUs. Pushing 28-32 Gbps per pin (vs GDDR6X's 21-24 Gbps), GDDR7 unlocks higher 4K and AI inference throughput at lower power. PAM3 signaling encodes 1.5 bits per cycle vs GDDR6X's PAM4 — different tradeoffs in noise margin and clock recovery.
