Lets Break it down a bit....
I apreciate you trying to break it down, but...
Where can I begin to explain the failed logic here? Is "25Mhz" the 'rating' for peak usage? average usage? min usage? Like in a database you cannot break it down to "Mhz per node" To many variables are involved to break it down that simply. And these numbers? where did you get them from?
I think we know where..
You sir know not of what you speak, please put this data back in the anus in which it came from. Come back when you have some idea of how large scale computing works.
