Chipsets have all sort of properties, including the instruction set, the consumption as you mention, their physical size and heat profile (related to consumption, but can be influenced by other factors) that make them better or worse for some applications. Your point on lens weight is valid, but I don't see it as something that should be in every single lens optic review, all the more so the use case of 50mm lenses are not just street snaps for instance.
