Real-Time Fluid Dynamics: CPU vs GPU

The best visual way to compare a CPU, real-time fluid simulation, against the GPU counterpart, is to run a benchmark for both at the same time, and perceive how much faster the GPU simulation outruns the CPU counterpart. This is what is done at the Real-Time Fluid Dynamics: CPU vs GPU demonstrative video. The author has ported the CUDA/OpenGL Fluid Simulation nVIDIA demo to a CPU version and then compared the performance of both implementations. More info. at
