NVIDIA GeForce GTX 1650

4 GB decides what fits. 128.1 GB/s decides how fast it runs once it does.

Quick answer
The NVIDIA GeForce GTX 1650 fits 70 of 320 sized models entirely in its 4 GB; the largest widely used one is Qwen3.5-4B (3.98 GB at Q4_K_M). Memory decides what fits; its 128.1 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 Qwen3.5-4B at Q4_K_M: 3.98 GB of the 4 GB, leaving 0.02 GB spare.

Fully resident at 8,192 tokens (or the model’s own maximum, where that is shorter), offload off, at 128.1 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

  • NVIDIA does not publish this card's memory bandwidth any more, so the figure comes from the TechPowerUp GPU Database (https://www.techpowerup.com/gpu-specs/geforce-gtx-1650.c3366), a third-party source, and is labelled as an estimate rather than a published specification.
  • 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.
