My first guess would be this: Start by verifying the driver/runtime combo, then test with a smaller prompt, then look at quant drift. A lot of these threads end up being one bad config plus a pile of conclusions drawn from it.

Can you fill in a bit more context? What model, what runtime, and roughly what context size?
throughput matters, but tail latency matters too

worth checking the driver first.
I'm happy to test one more variant if you want a second data point.
