So 2000 fps, 16 million pixels, and 7000 operations per pixel, works out to 224 TFLOPS.
An RTX 4090 is advertised as being able to compute 82 TFLOPS.
Where do you think the extra is coming from? Is it just straightforward optimisations like constant folding? Or do you think the compiler is noticing that 1000 iterations of the loop doesn't change the answer and optimising it down to just 1 loop?
