The new 9.9-inch tall Mac Pro case is about one-eighth the size of the Mac Pro tower. The entire top of the Mac Pro is a handle for carrying, and motion sensor lights show the I/O ports. The new design, according to Schiller, is based around a “unified thermal core” to help keep the machine cool.Apple didn’t just rely on the stunning, jaw-dropping design of the new Mac Pro for its sneak peek. Schiller offered a lot of specifics as to what’s under the hood.At the heart of the Mac Pro is a Xeon E5 processor, which is based on Intel’s Ivy Bridge microarchitecture and introduced by the company last April. Configurations with 12-cores will be available, and all Mac Pros will use third-generation PCI Express architecture. Apple is also using 1866MHz ECC DDR3 RAM.Schiller also went to great lengths to emphasize the new Mac Pro’s graphics performance. The machine will have dual AMD FirePro workstation-class GPUs, and be able to run three 4K displays at one time. Apple says the new Mac Pro’s graphics performance is 2.5 times faster than its predecessor.The Mac Pro is designed for speed, and Apple is outfitting the machine with PCIe-based flash memory, not traditional SATA hard drives or solid-state drives. Apple touts speeds of 1.25 GBps for reads and 1.0 GBps for writes. The company did not give specifics as to the amount of storage available.
