No, it cant be more space efficient. If you change your 4 cylinder car engine with an 8 cylinder engine, then it will need doubled space, too (if each cylinder is of similar size).

It is as easy as this. Double power -> double size.

However if you just want more horsepowers, you can try to build in a turbo charger/intercooler setup instead of the +4 cylinders. That would be the rough equivalent to Sandy's hyper-pipelined FPU ;-)
