notes
AUDIT CORRECTION: the dense/sparse flag on the tensor rows was inverted. FP16 312 / INT8 624 TFLOPS are DENSE. NVIDIA A100 page prints '312 | 624*' where * = With sparsity. These rows were previously flagged dense:false, which wrongly told a reader they were sparse. The stored numbers are correct dense values. Same Tensor Core throughput as A100 80GB SXM4 - the PCIe cut is memory-bandwidth and power limited, not compute limited. Tensor figures are WITH SPARSITY; dense is half (TF32 156, BF16/FP16 312, INT8 624 TOPS dense). NVLink on the PCIe card is bridge-only, up to 2 GPUs at 600 GB/s, versus SXM's full 600 GB/s with NVSwitch at up to 16 GPUs. 300W vs 400W. The 'other' row is FP64 9.7 TFLOPS (dense) - this schema's precision enum has no fp64 member.
