- Peak arithmetic rates are not token throughput, latency or a guarantee of application performance
- Structured-sparse rates require eligible sparsity and supported kernels; do not compare them directly with dense rates
- Dense low-precision tensor rates are not derived by halving sparse ratings
PLATFORM AND SOFTWARE
- Requires a compatible SXM5 server baseboard and cooling assembly
- An SXM module does not install in a conventional PCIe slot
- Confirm CUDA, driver and framework compatibility against the intended server image
- Ask whether any software subscription can transfer with the particular used offer
Manufacturer maximum accelerator rating; actual draw and supported limits depend on system
INTERCONNECT
NVLink
900 GB/s. Manufacturer aggregate bidirectional bandwidth; topology depends on platform
PCIe Gen5 x16
128 GB/s. Theoretical aggregate bidirectional interface bandwidth
