Apple previewed the new Mac Pro at its Worldwide Developers Conference. Based on what Apple revealed at the event and on it's dedicated Mac Pro website, here are the specifications for the new Mac Pro, expected to launch later this year. We will update this article as we get more information. 

According to Apple the new Mac Pro [read our preview of the new Mac Pro here] measures 25.14cm tall with a diameter of 16.76cm and will include the following:

  • The latest Intel Xeon E5 processor

The next generation Intel Xeon E5 processor chip will apparently boast three times the memory capacity of its predecessor and offer "exceptional energy efficiency," according to Intel.

  • Two AMD FirePro GPUs with 6GB dedicated VRAM

Apple says the two AMD GPUs offer up to 7 teraflops of performance - compared to 2.7 teraflops for the current Mac Pro. The company also claims the new Mac Pro will provide enough power to "seamlessly edit full-resolution 4K video while simultaneously rendering effects in the background – and still have enough power to drive three 4K-resolution (3840- by 2160-pixel) displays. There is some concern among video professionals that software will not be able to take advantage of these new graphics cards: read more about Video pros GPU and storage concerns

  • PCI Express-based flash storage offering 1,250MB/s

Apple is using PCI Express-based flash storage in the new Mac Pro. This storage is up to 2.5 times faster than the fastest SATA-based solid-state drive and up to 10 times faster than a 7200-rpm SATA hard drive, according to Apple.

  • 6 Thunderbolt 2 ports for up to 36 external devices

Users can daisy-chain up to six peripherals per Thunderbolt port, so you can plug in up to 36 external devices via Thunderbolt alone. Added to that, Thunderbolt 2 delivers twice the throughput of Thunderbolt, providing up to 20Gb/s of bandwidth to each external device.

  • USB 3, Gigabit Ethernet, 802.11ac Wi-Fi, Bluetooth 4.0, and HDMI 1.4 ports

There are four USB 3 ports; two Gigabit Ethernet ports so you can connect to multiple networks; 802.11ac Wi-Fi; Bluetooth 4.0; and an HDMI 1.4 port providing support for the latest televisions, projectors, and displays, including Ultra HD TVs. This replaces the pair of 16-lane PCI Express 2.0 slots and two 4-lane PCI Express 2.0 slots inside the current Mac Pro. There is also no optical drive - if you really need one an external Super Drive costs £65.

  • Four-channel ECC DDR2 memory running at 1866MHz

The new Mac pro will get up to 128GB of memory – twice as much as the current Mac Pro. The downside is that there are only four memory slots compared to eight in today's top-of-the-line model, so maxing out memory will require 32GB DIMMs, which will be very expensive. 

Speed - benchmarks

Geekbench seems to have some benchmarks for the new Mac Pro – even though the new pro Mac won't launch until later this year – and they suggest that the new Mac Pro will be much, much faster than the current Mac Pro with a Geekbench score of 23,901 compared to the 2012 Mac Pro's 21,980.
