The new Mac Pro is also extremely power-lopsided: it will initially max out at 12 cores (almost certainly this exact CPU), which is upper-midrange by Xeon standards, but it comes with a ridiculous amount of GPU power. This is overkill to just be about future desktop Retina Displays — clearly, Apple’s pushing for pro and scientific apps to shift more of the heavy lifting to OpenCL.
Also perfect for professional photo/video editing and graphic designers. To be honest, I almost wish I had a reason to buy one of these bad boys. Maybe I’ll get one for doing continuous integration with Xcode Server when my projects start involving more people.
