Can the RTX A6000 run it?
Can the RTX A6000 run Qwen3 32B?
Yes. Qwen3 32B needs about 22 GB and the RTX A6000 has 48 GB of VRAM. Expect about 21 tok/s, about reading speed.
Can the RTX A6000 run Llama 3.3 70B?
Yes. Llama 3.3 70B needs about 45 GB and the RTX A6000 has 48 GB of VRAM. Expect about 10 tok/s, slow, but it works.
Can the RTX A6000 run gpt-oss 120B?
No. gpt-oss 120B needs about 67 GB and the RTX A6000 has at most 48 GB of VRAM. Ollama can still start it by putting part of the model in system RAM, but it runs several times slower. The most capable model it runs well is Qwen3 32B, at about 21 tok/s.
Generating a token reads the model's active weights from memory once, so speed is roughly memory bandwidth (768 GB/s) divided by the active weight size, with efficiency calibrated on our own rack. Sizes are Ollama's default 4-bit downloads plus about 1.2 GB for context. Real results are usually within about a third. Measured one yourself? Send us the number.
The Ryzen AI Max+ 395 mini PC, 128 GB runs gpt-oss 120B at about 31 tok/s, from $3,400 used.
