Apple Begins Showing Mac Pro Teaser in Movie Theaters with 'Fall 2013' Announcement
According to reports from several people who have seen the teaser, it ends with the line "Fall 2013," offering the first concrete hint of when the redesigned Mac Pro might launch. At WWDC, Apple gave a "later this year" release date.
The new Mac Pro is a fraction of the size of the previous model and housed in a radically redesigned tower. It will come equipped with Intel Xeon E5 processors with up to 12 cores, dual workstation AMD FirePro GPUs, and new PCIe flash storage.
According to Apple, it is 2.5 times faster than the current Mac Pro, though benchmarks of the 12-core Xeon E5–2697 v2 processor have demonstrated mixed results, with the latest offering evidence that the Mac Pro will certainly offer a significant improvement over its predecessor, especially during demanding multi-threaded tasks.
It remains unclear when Apple might debut the Mac Pro in the fall months. The company is expected to hold an event for the iPhone 5S on September 10, with an iPad event to follow, and the Mac Pro could potentially surface at either time. Apple has also not announced pricing for the product, which is currently being assembled in the United States.
