Tensor parallel with the combined bandwidth, as in vLLM; llama.cpp splits layers by default and runs at about one card's speed.
Other options
- The next smaller setting, Q3_K_M, takes 8.92 GB at 32K, 7.08 GB under the RTX 5060 Ti; it fits with 0.5 GB to spare up to 79K tokens.
- Smallest setup for Q4_K_M at 32K: RTX 3060 12GB.
