AMD Instinct MI355X

288 GB decides what fits. 8000 GB/s decides how fast it runs once it does.

Quick answer

The AMD Instinct MI355X fits 286 of 320 sized models entirely in its 288 GB; the largest widely used one is MiniMax-M3 (264.0 GB at Q4_K_M). Memory decides what fits; its 8000 GB/s of bandwidth decides how fast it answers.

These examples are selected from prominent labs using the catalogue’s latest Hugging Face 30-day downloads and repository-creation freshness signal, with newer releases guaranteed a place. Offloaded rows assume 32 GB of system RAM, and a speed is only shown for a row that runs. Fitting in memory is not the same as loading: whether the runtime and version you have supports each architecture and format on this machine has not been tested here. Each “Open” link carries the same model, format, context and RAM into the calculator.

Fits entirely in AMD Instinct MI355X memory — 286 of 320 sized models

Every model that fitswhole model resident · offload off

The most demanding model that fits is MiniMax-Text-01 at Q4_K_M: 283.5 GB of the 288 GB, leaving 4.53 GB spare.

Fully resident at 8,192 tokens (or the model’s own maximum, where that is shorter), offload off, at 8000 GB/s. Each row is a run of the engine for this configuration; the rows start with current, prominent releases and “fits” is memory, not a tested runtime. Older or less prominent models remain available through this search and “Show all”.

Caveats

Per-OAM figures. AMD also publishes platform totals for eight accelerators, which are not used as single-device capacity.
AMD publishes no memory interface width for this part, so none is recorded.

Published capacity is a hardware ceiling, not guaranteed free runtime memory. The calculator shows the runtime reserve separately rather than folding it into a single number.
