    Multicore Desktop Processors & their desktop boards: Any risk to high def audio quality?

    all4audio

      With the end of the Window XP security updates, among other factors, I needed to take some time to replace my ancient tower pc, possibly with one that runs either an Intel Ivy Bridge 4 or 8 core or the latest Haswell 4 core processor.

       

      To minimize fan and/or electrical noise, the better choice appears to be the low powerversions of the Ivy Bridge processor family

      (http://en.wikipedia.org/wiki/List_of_Intel_Xeon_microprocessors#Xeon_E5-2xxx_v2_.28dual-processor.29 )

      E5-2630v2 (6 core, 2.6GHz, LGA2011 socket, 80w), E5-2630L v2 (6 core, 2.4GHz, LGA2011 socket, 60w), E5-2428L v2 (8 core, 1.8GHz, LGA1356 socket, 60w)-or the new Haswell processor family.

      (http://en.wikipedia.org/wiki/List_of_Intel_Xeon_microprocessors#.22Haswell.22_.2822_nm.29)

      E3-1285v3 (4 core, 3.1GHz, LGA1150 socket, 65w) and 

      (http://en.wikipedia.org/wiki/Intel_Haswell_%28microarchitecture%29#Desktop_processors)

      i7-4770S(4 core, 3.1GHz, LGA1150 socket, 65w), and i7-4770R(4 core, 3.2GHz, LGA1150 socket, 65w).

       

      Needless to say, my chief priority will always be audio signal quality (i.e. editing of uncompressed wav files of music CD tracks for playback via USB or a balanced AES card feeding a high performance external DAC). But I also would like to eventually use this computer for DVD as well as more demanding BluRay movie disc editing.

       

      Though presently having no hands on experience and minimal knowledge of computer video editing, I do know that the most time consuming phase of the process is recompression of the edited video back into the BluRay movie disc format. Depending on the software and hardware resources,
      recompression
      could take anywhere from 45 minutes to well over 90 minutes.

       

      So I thought that a new pc with one of the above six or eight core model processors and 16GB of RAM, together with the right software apps, might significantly reduce BD compression time-perhaps to as little as 30 minutes.

       

      Again,however, my primary concern is audio quality. Therefore, compared to the ubiquitous dual core processors, could using four, six or eight core Ivy Bridge or the new Haswell four core processors somehow pose any degree of risk to audio quality, in one or more ways?

       

      And of course, of particular interest would be any related incidents involving any of the specific (low power) processors listed above, and/or desktop boards they were used in.

       

      Before I make this computer purchase, any advice or referrals would be greatly appreciated.   Thank you.
