The latest and greatest Nehalem-based Xeon Mac Pros are the fastest Apple computers you can buy. Unfortunately, they seem to have a serious problem when processing audio, a task that sucks 20 per cent of its power while making the processors overheat.
According to Ars Technica, the problem - which happens with early 2009 and late 2009 models - doesn't only happen while playing iTunes' music or Quicktime videos, but also whenever you have USB or FireWire audio devices connected and working. Users have been reporting about in support boards.
Apple has ignored the problem so far, saying that the extra heat - which includes increases of 86F (30C) - was normal. The performance hit ranges from 15-20 per cent. Hopefully, they will start paying attention now. And hopefully, the problem won't happen with the incoming Core i7-980X Mac Pros, which are rumoured to be announced on March 16. [Ars Technica]
