Apple on Monday gave developers and the public a "sneak preview" of the next Mac Pro coming later this year -- a radical new "cannister" form factor in black that is 1/8th (by volume) the size of the previous model. It features a 12-core configuration based on all-new (but unnamed) Intel Xeon processors, dual AMD-provided workstation graphics, new PCIe flash storage, new faster RAM, PCI Express gen 3 support, the ability to use up to three 4K-quality displays, and external outputs dominated by Thunderbolt 2.
