RTX 2000 Ada vs RX 7600 XT for local AI

Q: Which is better for local AI, the RTX 2000 Ada or the RX 7600 XT?

The RX 7600 XT, for speed. They fit the same models. Both fit the same models we track, up to gpt-oss 20B. The RX 7600 XT generates about 29% faster on any model both can run, because it has 288 GB/s of memory bandwidth to the RTX 2000 Ada's 224 GB/s.

The numbers that matter

Memory and bandwidth

Memory decides which models fit. Bandwidth decides how fast they generate, because every token reads the model's active weights once.

Which should you get?

The RX 7600 XT, 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.

How we estimate

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.
