Whats the real world power difference between E5345's and X5355's?

    My Mac Pro has a pair of x5355's with a 120W TDP. After looking around the internet I ordered a pair of e5345's with an 80W TDP. The benchmarks show around 10% performance difference between the processor sets. How much less heat and less out of the wall can I expect in the real real world?

    Processors - E and X

    Hi,

    The wattage is lower using the "E" series processors and they have a lower TDP compared to the extreme, or "X". The performance would be negligible and not noticeable unless you are doing extreme video editing and or rendering + decoding.

    The E series are also energy efficient as they don't give off much heat compared to the X series. If heat is a concern for you then I would stay with the E series versus X series, but even I use X series on my 2010 Mac Pro and I have no problems with heat at all. Your milage may vary of course.
