Really solid breakdown of how llama.cpp behaves across CPU vs GPU and shared VRAM setups — especially the nuance around memory bandwidth vs raw compute.
One thing I’ve noticed building local-first LLM systems is that CPU inference is still surprisingly relevant in real deployments, especially in low-resource or offline environments where GPU access is either limited or inconsistent.
In those setups, predictable latency on CPU often matters more than peak throughput on GPU, even if the latter is faster on paper.
For example, in offline educational deployments (like a Gemma 4-based system I’ve been experimenting with), consistency across low-end hardware becomes more important than maximizing tokens/sec on high-end machines.
Curious if you’ve seen cases where CPU inference actually ends up being the more stable production choice despite GPU availability?
