Summary

User reports running Qwen 3.8 Flash-Next IQ3_S and Swift 1.5 IQ3_XXS on an RX 9060 XT 16GB with a 7800X3D and 64GB RAM. Setup is Strata, with Flash-Next at a 130K context window and Q8 KV cache, and Swift 1.5 at 262K context and Q4 KV cache. Token generation stayed between 40-55 tk/s across the whole context window for both models. Prompt processing was around 800 tk/s on resumed sessions and around 900 tk/s during compaction. Neither model could build the requested Figma plugin in one shot, but the user is happy with performance and plans to stay on the 9060 XT.
