so games benefit from dual processors? Is that always the case
because the
OS seperates the workload? I dont know exactly how dual processing
works on a
Mac and I think that is what many of us need to know.
Any app that uses more than one process thread will use both
processors in OS X. Also a single thread app can use all of one
processor while the other is used by everything else.
So, the answer is 'it depends on the app and what the app is doing'.
Apps do not have to be written in particular to use two processors,
but some, probably the majority of applications, will not really
benefit from DP anyway at least as such. You CAN run twice as many
applications as a single CPU for a given performance level.
But if an application is doing several things at once, or a single
task that can easily be split into parts (say, rendering a 3D scene
or a video transition) it will take the most advantage of dual
processors.
Everything will benefit somewhat if you do more than one thing at
once, but it's not as simple an equation as 2 400MHz processors = 1
800 MHz one.
