Comparisons on AlexNet are not very useful now. I can get AlexNet-like quality a lot cheaper (at test time) now, and for the same computational cost I can get a lot better in quality of results ... or even better if I accept more cost. I can't think of a good reason to evaluate AlexNet nowadays, I'm more annoyed at the other guys(tm) that (exclusively) do, since that means to get meaningful datapoints I need to rerun the experiments myself.

AlexNet #s IMO provide an excellent ballpark estimate of how well balanced compute and communication are in terms of both the framework and the underlying platform.

A platform that runs AlexNet well has excellent computation performance for the convolution layers but it also has excellent algorithms/communication for parallelizing the model/data by whatever means.

Networks that attempt to minimize computation and/or communication are cool, but they should be considered in that light IMO.

It's also a great estimate of the low-end for strong scaling. There's a lot of bread and butter machine learning at this level in my experience.
