Apple Mac Pro: Early benchmarks revealing

updated 07:32 am EST, Mon January 13, 2014

Apple Mac Pro is the definition of a high-end workstation

Ahead of our full review of the Apple Mac Pro (Late 2013), we have begun running some preliminary benchmarks in both OS X Mavericks as well as Windows 8.1 (64-bit). As we noted in our first look at the Mac Pro, our unit is the high-end standard configuration with a six-core Intel Xeon E5 processor clocked at 3.5GHz, matched with 16GB of RAM. As with all Mac Pro models, it comes fitted with dual AMD FirePro GPUs, which in this instance is a pair of FirePro D500s, each with 3GB of DDR5 VRAM. Our early benchmarking has yielded some interesting results, particularly in terms of the Mac Pro's graphics performance -- helping to clarify why the Mac Pro is classed as a 'workstation,' as opposed to a high-end 'desktop' computer or even gaming rig.

In our upcoming full review, we will run the Mac Pro up against our 13-inch MacBook Pro 2.5GHz (Retina Early 2013), and a 27-inch iMac (Late 2013), which we expect to receive from Apple shortly. In the meantime, we have run the Mac Pro up against the MacBook Pro, which it naturally leaves well and truly in the dust. However, while the MacBook Pro might not be much competition, the benchmark results of the Mac Pro raise some interesting discussion points.

For this sneak peak, we have focused on Cinebench R15 and Geekbench 3, which are are cross-platform compatible -- so we have also put the Mac Pro through its paces running Windows 8.1 using Bootcamp. We have also run the Mac Pro through Futuremark's 3DMark, which currently only works in Windows 8 (and iOS and Android), but not OS X -- it yields some interesting insights into the Mac Pro's graphics capabilities.

According to Maxon, Cinebench R15 is a real-world cross platform test suite that is based on its Cinema 4D software that has been used for making 3D content in films like Iron Man 3, Oblivion, Life of Piand Prometheus. The Open GL graphics test (which was our focus here) assesses the graphics card to deliver a result scored in frames per second (fps). The test pushes the GPU through one million polygons while measuring its geometry performance, along with textures and various effects. As you can see in the graphs below, the Mac Pro with D500 achieves a GPU score of 80.13fps. While it is one of the best results we have seen on a Mac, it will likely be outpaced by the dedicated (although mobile) NVIDIA GeForce GTX 780M graphics with 4GB GDDR5 that is available as a CTO option on the current iMac, along with the FirePro D700 upgrade option for the Mac Pro.



Interestingly though, when we ran the Mac Pro through Cinebench R15 in Windows 8.1 with CrossFire enabled, the Mac Pro blitzed the same test with a score of 106.13fps (CrossFire splits the graphics processing duties of a display in two, with each powering one half of the screen). Both Maxon and Apple have confirmed with MacNN and Electronista that Cinebench R15 is not yet optimized address both FirePro GPUs under Mac OS X. However, it is possible that it might not be optimized to use both GPUs for graphics processing, depending on how Maxon feels the two GPUs are best ultilized for running Cinema 4D in OS X on the new Mac Pros.

The GPUs in the Mac Pro are not designed for just graphics performance, but also for use in computing tasks thanks to Apple's implementation of Open CL in OS X Mavericks. When you learn that each of the FirePro D500s has 4.3 billion transistors, you begin to realize that there is a lot of computing power there that can be harnessed for running certain types of calculations, beyond just graphics processing. The Mac Pro utilizes the FirePro GPUs for professional apps like Final Cut Pro and DaVinci Resolve that can use the second GPU for off-screen rendering and computing.



If you're a gamer, you might wish that Apple and AMD work to enable CrossFire in OS X, but general computing is not what the Mac Pro is designed for (even if it remains excellent in that context too). If Apple had chosen high-end AMD gaming-oriented graphics card, a single one of these could out comfortably outscore one of the FirePro D500s in the Mac Pro, or even the higher-end FirePro D700. The AMD FirePro GPUs are designed for both graphics-intensive 3D applications as well as computing tasks, and are based on AMDs Graphics Core Next technology. This means that they are specifically designed for applications that utilize Open CL-enabled systems (like the Mac Pro), tasking highly complex computations between both the CPU and the GPU.

The reason the AMD FirePro workstation graphics cards are so expensive (each of the D500 cards in the Mac Pro, the equivalent of a W8000, sells for well over $1,000), is that they have been designed for 'mission critical' tasks and applications that take advantage of double precision numerics. This doesn't mean that you can't get solid gaming performance from the Mac Pro -- you can, as we have found when playing Windows games in 2560x1080 at ultra-high settings averaging around 60fps on recent titles like Batman: Arkham Origins -- but it is a side-benefit, not an aim.



In fact, the Futuremark 3DMark benchmark for Windows 8.1 attests to the solid gaming credentials of the Mac Pro -- it also reinforces that although the GPUs in the Mac Pro are high-end workstation cards, they are not going to threaten high-end gaming rigs and their respective GPUs in any way. The 3DMark (which assesses GPU performance across DirectX 11, geometry, illumination, particles, GPU simulations and a combined CPU/GPU stress test) compared the performance of the Mac Pro to scores achieved by gaming rigs. It revealed that the Mac Pro performs similarly to typical upper mid-range dedicated gaming cards.

As a side note, one of the tests in the suite is actually a cross-platform test, making it possible to directly compare the graphics performance of the iPad Air and the Mac Pro. In the common Ice Storm test, for interests' sake, the Mac Pro scores 139573 points, against the iPad Air's score of 15269. Where the iPad Air reached a peak frame rate of 104fps (exceptional for a current-gen tablet), the Mac Pro's dual D500 GPUs (with CrossFire enabled) punched through the same test at a peak of 1235fps -- not unexpectedly, of course, but interesting nonetheless.



The Geekbench 3 results produced by the Mac Pro in OS X and in Windows 8 were, as expected, roughly equivalent -- although there is a slight performance edge in OS X. If you are still wondering what makes the Mac Pro a workstation and not just a regular desktop, the multi-core performance should help to clarify your understanding further.

In terms of outright speed on single-threaded applications that tax just one core of a system's CPU, the new Mac Pro is certainly fast, but not staggeringly so -- we expect that when we compare its performance in the Geekbench 3 single-core test with the 27-inch iMac we have enroute, that it may not be much faster at all. Part of the reason for this is that the current iMac incorporates Intel's 'Haswell' microarchitecture, which is a generation ahead of the 'Ivy Bridge' microarchitecture underpinning its latest Xeon processors. Where the Mac Pro really shines is in powering through multithreaded applications across its multiple processing cores (six in this instance), as you can see from its superb multi-core score of 20683.



Remember, Apple offers eight and twelve core models as well -- for applications in the science laboratories, film studios, and 3D design studios, in particular, the new Mac Pro will excel at getting through intensive and complex processor, parallel processing, and 3D graphics intensive computations with ease. For our full review, we will publish some additional test results that we have run, including disk speed tests as well as ripping and encoding tests. We will also throw Apple's Pro applications -- including Final Cut Pro X, Logic Pro X and Aperture -- at the our Mac Pro as well, which have been optimized for it. Given the overall processing, RAM, storage, graphics, and I/O bandwidths of the new Mac Pro, we expect that it will handle just about anything we can throw at it. Look out for our full review of the Apple Mac Pro in the coming days to learn more about how it performs across a wide range of tasks.

    Four billion transistors just blows my mind. Anyway it's a shame that nobody seems to understand why Apple specifically builds computers for error-free use instead of absolute cutting-edge performance and the industry thinks that Apple is always trying to cheat buyers. Believe me, I'd rather have trouble-free computing than 5% more computing power if it comes at a risk. All I can say is that $4000 for the second-level Mac Pro seems like a bargain to me rather than a rip-off as some people are saying. I'd just as soon build my own NAS storage solution or add some aftermarket optical burner to complete my needs. I like that the new Mac Pro has a small footprint, is light in weight and is practically silent in operation.

    I actually don't see that much naysaying about the price of the Mac Pro from the critics. Sure, the trolls will always spew nonsense but real power users know what those graphics cards, the cpu, etc. cost and the Mac Pro is very competitively priced.

    Please tell me the real test isn't going to be with a Mac that has only 16-GB of RAM.

    @Ikrupp. I am a pro user, not a troll and I was looking so forward to getting a new mac pro but it just isn't going to happen. The problem is the price is all dependant on if your software takes advantage of the GPU's or not and unless you are a final cut user, most software doesn't. I use vectorworks/renderworks which is based on the cinema4d engine to do architectural renderings. I currently use a 12core 2.66 purchased in 2010 and all cores are maxed out when rendering. I paid $5000 for this system in 2010.

    Although this review uses Cinebench R15 to show how great the GPU's are, he failed to show the other test in that suite that shows the processor scores for rendering. From the preliminary numbers I have seen, the only config that will be faster than my 4 year old Mac is the new 12 core and not by much either. The cheapest config for that system is over $6500 and that's for the d300 version. That is not a great price for my use. Why would I pay $6500 to only slightly speed up what I already have.

    I have asked the developer on a forum about when/if they plan to use OpenCL to speed up rendering and they said they are years away from implementing that. So until I can get a system that speeds up what I can do by at least 50% for the same $5000, its not going to happen and that doesn't make me a troll.

    Would be interesting to see benchmarks / timings comparing the D300 to the D500. Some say the D300 is actually faster due to its higher clock rate, and few apps utilising double-precision numerics (that the D500 is better at).

    I think rather a lot of companies are taking an a lot more serious look at implementing OpenCL since the Mac Pro was announced.

    This machine puts some pressure on the market.

    If using OpenCL is as good as they say it is, I sure do hope so. The problem with this type of software package is that they are normally huge and most of the time have a window's version. This makes development and advancement very slow for architectural changes.

    I don't really care if the new mac pro is small, round, flat or if they put peddling gerbils in there to make it go. The bottom line to me is. Will this be faster than what I am using today for what I am using it for. The answer for us 3D Pro's or any other software that is processor heavy and GPU light, is sadly No. At this time, my 4 year old system is just as fast or faster and at a way cheaper price. If and when OpenCL gets implemented in my software, I will definitely re-look into this but from what I heard from my developer, that won't be for a while.
