Notes on these figures
memory_gb = 252 HBM3e + 496 LPDDR5X (NVIDIA: 748 GB coherent). Bandwidth 7.1 TB/s is GPU HBM3e; CPU LPDDR5X is 396 GB/s. FP4 = 15 PFLOPS dense (20 PFLOPS sparse, the headline platform figure). FP8 (10 PFLOPS) and FP16/BF16 (5 PFLOPS) are SPARSE figures; dense not published. tdp_w = total system power 1,600 W, 20A circuit required. Sold via OEM partners (ASUS, Dell, GIGABYTE, HP, MSI, Supermicro, Exxact per NVIDIA PR 2026-07-20); no NVIDIA price. Announced 2025; first-ship year not confirmed in an NVIDIA source.
