Next Generation OS - Multi Processor Or 128 Bit

As you increase the number of processors the performance improvement diminishes compared with the expected result -- for instance a system with 8 processors won't perform 8 times faster than a system with one processor due to the ovehead of managing the extra complexity of the interaction of all the processors. (Note the system will still be FAST of course !!).

Now wouldn't it be better to design say 128 and 256 bit architectures in the OS so you could still run many tasks concurrently but without the overhead of the multi processor environment - or at least have far less processors in the MP environment.

it was rumoured a while back that Windows 8 would have some 128 bit possibility -- I don't think there are any commercially available chips yet but thats only a matter of time.
