VRAM bottleneck on consumer cards

[signaltrack44]

Did a bit of testing and thought I'd post the result here.

I tried this with Mistral using TensorRT-LLM on 5090. The headline result was better than I expected, but HBM constraints still ended up being the limiting factor.

Nothing scientific here, just practical notes from a real setup.

My use case is pretty ordinary: local chat, some document work, and occasional batch jobs.

following this because I'm in the same boat.

I think the bottleneck is somewhere else. I get why that seems right, but on B200 the bottleneck felt elsewhere. Could be a workload difference, but I wouldn't generalize too fast from one setup.

If you post your exact settings, people here can probably narrow it down pretty fast.
