Refurbished Apple Mac Pro 3.7GHz Quad-Core Intel Xeon E5, 12GB RAM, 256GB Flash (Late 2013) - A

Mac Pro is the professional desktop computer reinvented from the inside out. Arranging the most advanced technologies available around a unified thermal core allowed us to make this the most powerful and expandable Mac ever, yet also unbelievably compact and quiet.

Mac Pro comes as standard with two workstation-class AMD FirePro graphics cards, enabling powerful GPU-based visualisation and compute capabilities in every system. Both GPUs are connected internally via x16 PCI Express gen 3 lanes for massive bandwidth. The FirePro GPUs in Mac Pro enable video output through both the Thunderbolt 2 ports and the HDMI 1.4 port, enabling you to connect up to three 4K displays or up to six Apple Thunderbolt Displays.

Every component in the new Mac Pro is optimised for performance. That includes a four-channel DDR3 memory controller running at 1866MHz. It supports up to 64GB of memory and delivers up to 60 GB/s of memory bandwidth, which means you can fly through even the most computer-intensive tasks in no time. And since it’s ECC memory, your render job, video export or simulation won’t be stopped by transient memory errors.

The new Mac Pro features the latest Intel Xeon E5 processor, with up to 12-core processing power and a four-channel memory controller providing up to 60 GB/s of memory bandwidth, all on a single die. And with 40 lanes of PCI Express gen 3 throughput, up to 30MB of L3 cache and over 500 gigaflops at peak performance, you’ll never be at a loss for speed.

There’s flash storage, and then there’s next-generation PCIe-based flash storage. We’re talking storage that’s up to 2.4 times faster than the fastest SATA-based solid-state drive and up to 10 times faster than a 7200-rpm SATA hard drive. Most flash storage systems connect via SATA buses designed for slower-spinning hard drives. But we designed the new Mac Pro around new PCIe-based flash controller technology to deliver the fastest solid-state drives available as standard in a desktop computer.

Thunderbolt combines PCI Express and DisplayPort into one high-speed, versatile I/O technology. And with Mac Pro, we’re jumping even further ahead. Thunderbolt 2 delivers twice the throughput, providing up to 20 Gb/s of bandwidth to each external device. So you’re more than ready for the next generation of high-performance peripherals, without being limited by the number of expansion slots inside your computer. You can connect massive amounts of storage, add a PCI expansion chassis and work with the latest external displays — including 4K desktop displays and peripheral devices capable of broadcast monitoring in 4K. And since each Thunderbolt 2 port allows you to daisy-chain up to six peripherals, you can go all out by plugging in up to 36 external devices via Thunderbolt 2 alone.
