GPUs are happiest when doing float precision, which is 24 bits.<p>Most GPUs can, at reduced speed, do double precision, which is 53 bits.<p>The maximum precision for this zoom movie is 960 bits.<p>So, unless you write code to compose high-precision math operations out of double-precision math then the GPU cannot even participate. And once you do that you will find that the GPU&#x27;s speed advantage is mostly or entirely lost.
