I'm running a Ryzen 7 8745HS with Radeon 780M (27GB RAM), using Ollama's Vulkan backend.
I get ~45 tokens/s generation and ~680 tokens/s prompt processing.
The problem is ollama is not caching the prompt, I get -> forcing full prompt re-processing due to lack of cache data
So this wouldn't work in its current state in an agentic loop.
Ollama is generally just not great software. Use something else and you likely won't have that issue.
