Key points
- I ran it on a single 3090 benchmarked it with qwen 3.8 27B before and after the optimization and saw these results:
- All tests passed without GPU errors.
- Edit: Keep in mind performance gains can be higher, my 3090 is power limited to 230 watts including during my tests
- Didnt expect much but got z-turbo image gen to go from 18s down to 12 seconds....
