147 of 320 fit entirely
147 of the 320 models the engine can size fit entirely in device memory at Q4_K_M where it is published, otherwise the nearest published format, and 8,192 tokens. 70 run with some layers on system memory (32 GB assumed), and 103 do not run at all.

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 Radeon RX 6750 XT memory — 147 of 320 sized models
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 432 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 432 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.
