alt Hacker NewsI'm running on Strix Halo so memory bandwidth is my constraint. In that example I'm describing the choice between using ROCm or Vulkan. I have a llama-swap config that can call different instances of llama-server running a toolbox with either runtime.
Memory bandwidth is my constraint too (M4 Max) but prefill and single-token decode don't run at the same time. It's best to use batched prefill so you can benefit from processing multiple tokens with a single pass through the model weights.
