- 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
- The June 2021 manufacturer table explicitly spans all four memory/form-factor variants; equal listed compute rates do not imply equal memory bandwidth or power
PLATFORM AND SOFTWARE
- Requires an SXM4 baseboard
- An SXM4 module is not interchangeable with an SXM5 module
- Confirm driver and framework support for the intended deployment image
- Benchmark the exact precision and batch settings instead of comparing theoretical tensor figures
Manufacturer maximum accelerator rating; actual draw and supported limits depend on system
INTERCONNECT
NVLink
600 GB/s. Manufacturer aggregate bidirectional bandwidth; topology depends on platform
PCIe Gen4 x16
64 GB/s. Theoretical aggregate bidirectional interface bandwidth
