There are many factors why we did not do this.

1. The point of this post is NOT to compare AMD vs Intel or NVIDIA. We wanted to show realistically how single and double precision performs on off the shelf GPUs and server GPUs. 

2. The OpenCL blas library we were using for the benchmark (clBLAS) is highly tuned for AMD GPUs only. Comparing the performance of clBLAs on NVIDIA and Intel GPUs will not provide the right picture.

3. We are using the hardware that was giving to us by our partners. To re-iterate we were not trying to pit one hardware against the other, we were trying to something else entirely. 

There is a reason we did not put the different GPUs on the same graph. It is so people don't make the assumption that we are comparing NVIDIA to AMD. We were trying to compare 32 bit vs 64 bit floating point performance on individual architectures. You are unnecessarily reading between the lines and accusing us of something that we are not doing.
