NVIDIA Vera Rubin NVL72
Rack-scale system pairing 72 Rubin GPUs with 36 Vera CPUs (3,168 Olympus Arm cores total, 54 TB LPDDR5X CPU memory). Headline NVFP4 inference 3,600 PFLOPS dense; NVFP4 training 2,520 PFLOPS dense. Tensor-core-emulated FP32 SGEMM reaches 28.8 PFLOPS, FP64 DGEMM 14.4 PFLOPS. Aggregate memory shown is HBM4 only (CPU LPDDR5X is excluded from GPU memory aggregate). Total chips per rack: 1,296. Specifications preliminary per NVIDIA GTC 2025 footnote.

Where a vendor states a basis, the figure shown is the dense one, and any figure it publishes is listed separately. Vendors commonly headline the sparse number instead: for NVIDIA's 2:4 structured sparsity that is exactly twice the dense figure, though other vendors' sparse modes do not all follow that ratio.
