Apple in April 2017 confirmed that a new redesigned Mac Pro will be released in 2018 or 2019 to replace the 2nd generation Mac Pro
The Mac Pro line is a series of Intel Xeon–based workstation and server computers manufactured by Apple Inc. The Mac Pro, in most configurations and in terms of speed and performance, is the most powerful computer that Apple offers. It is the high-end model of the three desktop computers in the current Mac lineup, the other two being the iMac and Mac Mini.
The first-generation Mac Pro has a rectangular tower case which outwardly resembles the last version of the Power Mac G5, and has similar expansion capabilities. The first Mac Pro offered a dual Dual-core Xeon Woodcrest processors. It was replaced by a dual Quad-core Xeon Clovertown model on April 4, 2007, and again on January 8, 2008 by a dual Quad-core Xeon Harpertown model. The 2012 Mac Pro is largely based on a model that was announced on July 27, 2010. It features Nehalem/Westmere architecture Intel Xeon processors. These CPUs offer optionally twelve processing cores. The machine itself at its most evolved is able to accommodate up to four 2 TB hard disk drives or 512 GB solid state drives, as well as the ATI Radeon HD 5770/5870 GPU units, one per slot.
The second-generation design of Mac Pro was announced at the 2013 Apple Worldwide Developers Conference (WWDC) opening keynote on June 10, 2013. Apple states that the new Mac Pro achieves twice the overall performance of the last model. The redesigned Mac Pro takes up less than one eighth the volume of immediately previous model, being shorter (9.9 inches (25 cm)), thinner (6.6 inches (17 cm)) and less massive (11 pounds (5.0 kg)). The machine supports one central processing unit (CPU) (up to a 12-core Xeon E5 CPU), four 1866 MHz DDR3 slots, dual AMD FirePro D series GPUs (up to D700 with 6 GB VRAM each), and PCIe-based flash storage. There is updated wireless communication and support for six displays.
