How much brain power per KG/volume?

When writing a futuristic story I always try to minimise the impact of computerization. Its rather uncomfortable writig a story when technology is advanced enough that humans arent in a position to come into conflict with one another.

One thing about my current setting is that they use biological robots to compensate for the lack of computer power to do their bidding. As a consequence they would be able to build enormous brains to do their research or control large scale projects. Which in turn raises the question: how much brain power could I expect from such a thing?

If we look at brains of the greats like Steven hawking, Einstein or John Von Neumann we could expect great things if we scaled their brains up. But when comparing brains to computers, its the computers that always take the cake. This is a bit of an unfair comparison as much of our brains isnt busy with the important calculations but with unimportant stuff like keeping your chemical balance in check, staying upright, thinking of how to act in social situations, handling the complexity of laguage, how to have sex with a good partner, gathering food and other trivial things.

So I'm wondering, if we assume the minimum brain power for survival is met, how much brainpower can I expect from each KG/Volume of brain?

If that makes it easier (it probably wont), lets say we have a brain of 6 metric tons (and a few tons of biomaterial to keep it alive and interacting in some form with the world).
