Quick answer
The AMD Radeon RX 6700 XT fits 147 of 320 sized models entirely in its 12 GB; the largest widely used one is Qwen2.5-Coder-14B-Instruct (11.4 GB at Q4_K_M). Memory decides what fits; its 384 GB/s of bandwidth decides how fast it answers.

At 8,192 tokens of context with the whole model in device memory. Speeds are estimates from memory bandwidth, not benchmarks run on this card.

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.

Every model that fitswhole model resident · offload off

The most demanding model that fits is Qwen2.5-Coder-14B-Instruct at Q4_K_M: 11.4 GB of the 12 GB, leaving 0.60 GB spare.

Fully resident at 8,192 tokens (or the model’s own maximum, where that is shorter), offload off, at 384 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

  • AMD publishes bandwidth as "Up to 384 GB/s"; that ceiling is the figure used. The Infinity Cache raises AMD's "effective" figure for games; decoding a model streams far more than the cache holds, so the raw memory bandwidth is the one that decides the speed.
  • No dense matrix throughput is published for this device in a form this catalogue accepts, so no compute roof is priced and time to first token is withheld.

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.
