Whereas OpenCL is likely to require more programming to fill in the gaps for library support, and different optimisations depending on the architecture you wish to target. I&#x27;m guessing since then, the CUDA compiler may have improved somewhat in terms of optimisation based on some micro-benchmarking research I was looking the at the…</p><p><a href="https://hackerpaper.kaipfister.de/p/1311.0378/">Paper and discussion history</a>.
