GPU Performance

The implementation of the algorithm on the GPU achieves the same results as the CPU, but is implemented in a different way. GPU hardware also has different strengths and weaknesses when compared to those of the CPU. In addition, different hardware vendors have their own pros and cons. Taken together, it’s impossible to give an exact performance ratio of CPU to GPU. However, some general guidelines can help you get the most out of your GPU.
