What is the biggest model the Titan RTX can run?

Qwen3 32B, which needs about 22 GB, on the 24 GB version at about 18 tok/s.

What is the biggest model the A10 can run?

Qwen3 32B, which needs about 22 GB, on the 24 GB version at about 17 tok/s.

Titan RTX vs A10 for local AI

Q: Which is better for local AI, the Titan RTX or the A10?

The Titan RTX, for speed. They fit the same models. Both fit the same models we track, up to Qwen3 32B. The Titan RTX generates about 12% faster on any model both can run, because it has 672 GB/s of memory bandwidth to the A10's 600 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 Titan RTX, 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.
