What is the AMD Instinct MI100?

The Instinct MI100 is a GPU from AMD on the CDNA architecture, an accelerator for AI training, inference and high-performance computing. It is a PCIe add-in card, so it fits standard servers and workstations. Instinct MI100 full specifications →

Can I rent the Instinct MI100 in the cloud?

Flopper is not tracking any live rental listings for the Instinct MI100 yet. The provider directory lists the clouds that rent comparable accelerators on demand. GPU cloud providers →

How does the Instinct MI100 compare with other accelerators?

This page sets the Instinct MI100 against the L40. The Instinct MI100 is the older generation of the two. This is a cross-vendor matchup, AMD against NVIDIA, and both ship as a PCIe card, so they fit the same class of system. The compare tool builds the same comparison for any two parts in the catalogue.

FLOPS by Precision

What actually differs

The L40 is the newer part: Ada Lovelace (2023) against the Instinct MI100's CDNA (2020).

The L40 carries 16 GB more memory (48 GB against 32 GB), so larger models fit on one GPU before you shard. Bandwidth is 1.2 TB/s against 864 GB/s, which sets the ceiling on decode speed.

Power is 300 W against 300 W, and at FP32 the L40 does more work per watt. Weight the FP8 and FP16 rows for LLM work and the FP64 row for HPC.
