  • 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
  • NVIDIA September 2023 article explicitly reports these theoretical PCIe rates; an older linked H100 datasheet reports different preliminary values and is not merged into this table
  • Low-precision tensor values omitted pending an exact PCIe source with unambiguous sparsity footnotes; no SXM or NVL figures substituted
  • Compute values are reported specifications, not derived from CUDA-core count or assumed boost clocks

PLATFORM AND SOFTWARE

  • Passive cooling requires suitable server airflow
  • Confirm power cabling and three-bridge set when requesting an NVLink pair
  • NVLink uses the 600 GB/s value in Table 6; the brief introduction contains a conflicting figure
  • 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

600 GB/s. Manufacturer aggregate bidirectional bandwidth; topology depends on platform

PCIe Gen5 x16

128 GB/s. Theoretical aggregate bidirectional interface bandwidth

HOW CARDINAL HELPS

Share your quantity, destination and server model, if known. We help turn those requirements into a clearly specified request.

  • Help confirm the exact configuration and platform requirements
  • Request supplier records for condition, unit identifiers and available testing evidence
  • Clarify included accessories, delivery and proposed warranty terms before you decide

Any additional testing or guarantees must be agreed in the written offer.
