This is game changing. My R9700 32GB is now smarter and about 2x faster than using Qwen-3.8-27B. About 60 t/s when combined with my 96GB of DDR4. My motherboard limits me to PCIe Gen3 so that is likely a bottleneck.

Even got it running on the iGPU of a GMKTec M6 Ryzen 6600H at reasonable speed (10 t/s). Fast enough to leave it with a prompt before I go to bed and wake up to a solution.
