I think your project is both cool and potentially very useful and I'm glad you mentioned it on HN! Having said that, your numbers jumped out a bit at me - the Mandelbrot and nbody/perlin numbers are in the ballpark of what I'd expect for a "random high end consumer CPU" -> 3090 transition, roughly, but the saxpy seems way off. A saxpy kernel is both trivial to write optimally and trivially memory bound virtually everywhere, so between a 3090 and a dual channel DDR5-6000 system there should pretty much always be a ~10x difference. Any idea what's going on there?
