The Mac Pro isn't for everybody, and not just because it's Apple's highest-priced computer. It is made to excel with a certain type of app: professional software that uses multiple processing cores, like software commonly used by videographers, photographers, animators, designers, scientists, and musicians. If that describes what you do on a daily basis, then you'll benefit from a Mac Pro -- you'll make your money back in time saved.
This guide takes a look at the Mac Pro's specifications, design, and performance. If you're in the market for a Mac Pro and you're not sure which model to buy, this guide will help you sort it all out.
Apple offers two standard configurations. You can pick one of the standard configurations, but the Mac Pro is all about custom configurations. Think of the standard configurations as a starting point, and you can then customize your order to better suit your needs.
The $2999 Mac Pro:
- 3.7GHz Quad-Core Intel Xeon E5 processor
- 12GB 1866MHz DDR3 ECC memory
- Dual 2GB AMD FirePro D300 graphics cards
- 256GB PCIe-based flash storage
- 3.5GHz 6-Core Intel Xeon E5 processor
- 16GB 1866MHz DDR3 ECC memory
- Dual 3GB AMD FirePro D500 graphics cards
- 256GB PCIe-based flash storage
Apple offers the following upgrades for the Mac Pro:
- 3.0GHz 8-core processor or 2.7GHz 12-core processor ($500 to $3,500 extra)
- 16GB, 32GB, or 64GB of RAM ($100 to $1,300 extra)
- 512GB or 1TB of flash storage ($300 to $800 extra)
- Dual 6GB AMD FirePro D700 graphics cards ($1000 extra)
Since the Mac Pro is such a compact computer, there's no room for adding extra drives or expansion cards like you would in the old Mac Pro tower, so you have to rely on the external ports. Fortunately, Apple includes a lot of them, but it also means you may have several external boxes sitting next to your Mac Pro, as well as a bunch of power plugs. Apple includes the following ports:
- Four USB 3 ports
- Six Thunderbolt 2 ports
- Dual Gigabit Ethernet
- One HDMI port

You've probably heard all the talk about the Mac Pro being Apple's fastest Mac. It's true, for the most part. The Mac Pro is designed with multi-core processing in mind, and the Mac Pro does its best when using apps that can take advantage of multiple cores -- high-end video editors, 3D renderers, audio editors, compilers, and other apps used by professionals.
The benchmarks prove this out. Several sites have published benchmarks that demonstrate the Mac Pro's multi-core prowess. Geekbench 3 results show that in its 64-bit multi-core tests, the 12-core Mac Pro is unsurprisingly the top performer.
The results also predictably show that performance increases when you have more cores. After the 12-core Mac Pro is the 8-core model, followed by the 6-core and quad-core Mac Pros. When buying a Mac Pro, it pays to upgrade the processor. Get what you can afford. AnandTech and Macworld have more details about pro apps and performance.
The Mac Pro stumbles a little when it comes to single-core performance. Apps that only take advantage of a single-core include those that most general consumers would use every day -- email, browser, productivity apps, consumer level video and audio editors, etc. In fact, the iMac is a better single-core performer.
If your Mac is an everyday general use computer and you have the desk space, you're better off getting an iMac than a Mac Pro.
To get more performance out of your Mac Pro, consider upgrading the graphics cards. AnandTech's testing shows that some apps, like Final Cut Pro, take advantage of the two graphics processors in the Mac Pro, especially when rendering effects. However, there are apps (and most games) that aren't written to split compute tasks over two GPUs; one GPU is used for basic display duties, while the other covers the compute tasks, so there isn't a distinct advantage to a graphics card upgrade. If you work in pro apps, do some research to see if they can take full advantage of a dual graphics card setup.
The role of the Retina iMac
Apple released the 27-inch iMac with Retina 5K Display in October of 2014. With its 5120 by 2880 pixel display, it seems like a desirable computer for pros.
However, in multi-core performance, the Mac Pro is still king. In Geekbench multi-core testing, the 12-core Mac Pro is nearly 100 percent faster than the Retina iMac, while the 8-core is 55 percent faster and the 6-core is 27 percent faster. The Retina iMac does outperform the quad-core Mac Pro, by about 15 percent.
The Retina iMac does beat the Mac Pro in single-core performance, as you can see in the Geekbench charts above. Primate Labs, the developers of Geekbench, took a closer look at the performance between the Retina iMac and the Mac Pro.
The Mac Pro doesn't have the ability (yet) to drive a 5K display, but it can support up to three 4K displays. Apple had to build a custom controller for the Retina iMac to support a 5K display, so if you absolutely need a 5K display, the Retina iMac is your only choice.
If you're thinking of using the Retina iMac as an external display for the Mac Pro, you're out of luck. The Retina iMac doesn't support target display mode.
Which Mac Pro should you buy?
First, should you buy a Mac Pro in the first place? If you're a professional using high-end apps that can take advantage of multiple processing cores, then yes, a Mac Pro is the right computer for you. The Mac Pro is made for those kind of apps, and you'll be quite productive with such a machine.
If you just love the design of the Mac Pro and have the money, who's going to stop you from buying one? It is, after all, the smallest headless desktop computer Apple offers that isn't crippled like the Mac mini. Just understand what the Mac Pro is designed to do.
OK, so you're getting a Mac Pro. Which one? It's worth it to go for the $3999 model with the six-core processor. If you can afford to upgrade to eight or 12 cores, go for it. You'll see the performance boost with apps that can take advantage of multiple cores. The $2999 quad-core Mac Pro is a good performer, but in Geekbench 3 multi-core benchmarks, it's actually outperformed by the $2499 Retina iMac, which ends up being a better value. (It has been nearly a year since the Mac Pro was released, so a processor speed bump could happen sooner than later.)
The more RAM the better is also a good general guide, so try to bump up to at least 32GB if you're going to be doing intensive work on the machine. Storage is one area where you might be able to skimp, however, if only because the Mac Pro maxes out at 1TB and professional level users are likely going to be using much larger external RAID drives for speed, data protection, and capacity.
