Can the RTX 3080 Ti run it?
Can the RTX 3080 Ti run Gemma 3 12B?
Yes. Gemma 3 12B needs about 10 GB and the RTX 3080 Ti has 12 GB of VRAM. Expect about 62 tok/s, faster than you can read.
Can the RTX 3080 Ti run Qwen3 14B?
Yes. Qwen3 14B needs about 11 GB and the RTX 3080 Ti has 12 GB of VRAM. Expect about 54 tok/s, faster than you can read.
Can the RTX 3080 Ti run gpt-oss 20B?
No. gpt-oss 20B needs about 16 GB and the RTX 3080 Ti has at most 12 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 14B, at about 54 tok/s.
Generating a token reads the model's active weights from memory once, so speed is roughly memory bandwidth (912 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 Used workstation + 2× Tesla P100 runs Qwen3 32B at about 20 tok/s, from $750 used.
