GTX 970 vs GTX 1650 for local AI
Both fit the same models we track, up to Qwen3 4B. The GTX 970 generates about 75% faster on any model both can run, because it has 224 GB/s of memory bandwidth to the GTX 1650's 128 GB/s.
Memory and bandwidth
Memory decides which models fit. Bandwidth decides how fast they generate, because every token reads the model's active weights once.
Every model, side by side
Estimated generation speed at the largest memory size each was sold in (4 GB and 4 GB).

The GTX 970, for speed. They fit the same models. Price matters as much as either number: check used prices on the builds page, where every parts list has a measured or estimated speed.
Both columns use the same formula: memory bandwidth divided by the weights read per token, calibrated on our own rack, with Ollama's default 4-bit sizes. Real results are usually within about a third. Measured either one? Send us the number.
