Do the newest GPUs run faster on
the 2010 Mac Pro than on
the 2009 and 2008 Mac Pro?

Posted Friday, May 10th, 2013 by rob-ART morgan, mad scientist

We have stated in past articles that both the Sapphire Radeon HD 7950 Mac Edition and the EVGA GeForce GTX 680 Mac Edition are compatible with the 2008 Mac Pro and later. However, we received reports that these GPUs were running slower on the 2008 Mac Pro compared to our posted results for the 2010 Mac Pro. PowerMax.com provided us with a 2008 Mac Pro so we could find out for ourselves.

We tested both new GPUs in the 2008, 2009, 2010 Mac Pro using the same Velociraptor 1TB OS X 10.8.3 boot drive. We included the best 'legacy' GPU, the Radeon HD 5870 -- still available as a CTO option on new Mac Pros as well as in kit form.

2008 + 5870 = Factory AMD Radeon HD 5870 in 2008 Mac Pro 3.0GHz 8-core
All three Mac Pros had at least 16GB of main memory.

Motion 5comes with various project templates. We use the 'Atmospheric - Open' 600 frame 1920x1080 template for our test. We time how long it takes to render the RAM Preview and then calculate the speed in frames per second. (LONGER means bar means FASTER AVERAGE frames per second.)

Cinema 4D OpenGL Animation -- We took the 'Car Chase' from Cinebench 11.5, opened it in Cinema 4D, and played it back with max FPS set to 500 -- forcing the animation to run as fast as it could on a given GPU. OpenGL preferences were Texture Mode = Mipmap, Anti-Aliasing = 4, Maximum Transparency = 2, Maximum Lights = 5, Maximum Shadows = 2. Display setting was Gouraud Shading. (LONGER means bar means FASTER AVERAGE frames per second.)

DaVinci Resolve 9adds speed and power to color grading of HD video. It uses the GPU to apply and playback using specified effects in real time -- no pre-rendering required. However, the more effect nodes created, the slower the playback.

The first graph features 8 clips (766 frames) of a 32 second 1920x1080 10-bit YUV 4:2:2 SDI 24fps video. We set the maximum playback framerate to 300 fps. We wanted to see how fast each GPU could playback with three nodes (including color correction and blur). Results are average frames per second. (LONGER means bar means FASTER AVERAGE frames per second.)

The second graph is using the popular Candle Test. (Not sure why it's called candle because the sample 4 second video clip features a parrot.) We set the playback rate to 300 fps to push it to playback the four blur nodes faster than the 24 fps target rate. (LONGER means bar means FASTER AVERAGE frames per second.)

Unigine's Valley 'flies' through forest-covered valley surrounded by vast mountains. It's a bird’s-eye view of 64 million meters of extremely detailed terrain down to every leaf and flower petal. It features advanced visual technologies: dynamic sky, volumetric clouds, sun shafts, DOF, ambient occlusion. (It is cross platform. For Windows users it is a test of DirectX.) We used Extreme preset: 1600x900 windowed resolution with 8x Anti-aliasing, Ultra Quality for Shaders and Textures, and with Occlusion, Refraction, and Volumetric Shadows enabled. (LONGER means bar means FASTER AVERAGE frames per second.)

INSIGHTS
1. In the case of the GTX 680 and Radeon 5870, Motion's performance improved as the Mac Pro got newer. The Radeon 7950, however, was stuck in low gear no matter what Mac Pro model we used.

2. Cinema 4D gained speed as we progressed from older to newer Mac Pro, but none of the three GPUs tested had a significant advantage over the others.

3. The 2008 Mac Pro displayed a definite handicap compared to the 2009 and 2010 in the two DaVinci Resolves tests.

4. The Valley benchmark ran faster on the newer Mac Pros when the GeForce GTX 680 was used. But both Radeon GPUs saw no improvement when installed in a newer Mac Pro.

OVERALL
Though our sample of tests is not exhaustive, the newest GPUs generally run faster in the newer Mac Pro towers. If and when a 2013 Mac Pro were to appear with Ivy Bridge Xeon and PCIe 3.0, it's very likely these new GPUs would perform even better with certain GPU intensive apps (if our experience with the 2012 iMac is any indication).

Oh, and by the way, we can confirm that both the Radeon HD 7950 Mac Edition and GeForce GTX 680 Mac Edition are fully compatible with the 2008 Mac Pro.

PART ONE: EVGA GeForce GTX 680
'Mac Edition'
versus Past and Present Mac GPUs

Posted Tuesday, April 16th, 2013 by rob-ART morgan, mad scientist
April 17th updated comments on multiple displays (see #2 in insights)

Things are getting exciting for owners of 2008 - 2012 Mac Pros. Yet another graphics processor upgrade is shipping: the EVGA GeForce GTX 680 Mac Edition. Let's see how it compares to other Mac Pro GPUs past and present.

GRAPH LEGEND
GTX 680 Mac = EVGA NVIDIA GeForce GTX 680 Mac Edition (2G VRAM)
QK5000 = NVIDIA Quadro K5000 for Mac (4G VRAM)
Quadro 4000 = NVIDIA Quadro 4000 for Mac (2G VRAM)
GTX 285 = NVIDIA GeForce GTX 285 for Mac (1G VRAM)
GT 120 = NVIDIA GT 120 GPU (512M VRAM)
Radeon 7950 = Sapphire AMD Radeon HD 7950 GPU (3G VRAM)
Radeon 5870 = AMD Radeon HD 5870 GPU (1G VRAM)
Radeon 5770 = AMD Radeon HD 5770 GPU (1G VRAM)
Radeon 4870 = AMD Radeon HD 4870 GPU (512 VRAM)
GTX680MX = NVIDIA GeForce GTX 680MX (iMac 2012; 2G VRAM)

All Mac Pro GPUs above were in a in a 'Mid 2010' Mac Pro 3.33GHz Hex-Core. The GeForce GTX 680MX is the only exception -- embedded in the 'Late 2012' (27') iMac 3.4GHz Core i7. Both Macs were running OS X 10.8.3.

StarCraft II: Heart of the Swarm-- In the Rat Lab, the various mutations are complete. Settings are 2560x1440 Fullscreen, Ultra and Extreme, vSync OFF, no AA. (LONGEST bar indicates FASTEST in frames per second.)

Diablo III-- 'Evil is in its prime.' Our lonely traveler is on the path to adventure stopping occasionally to kill a few zombies. Settings are 2560x1440 Fullscreen, vSync OFF, Best Quality, Anti Aliasing enabled. (LONGEST bar indicates FASTEST in frames per second.)

Civilization Vis now on Steam. By entering '-LeaderBenchmark' in the Properties > Set Launch Options, it runs through multiple animated sequences of the various World Leaders. Though it does not simulate real game play, it is GPU intensive. Resolution was 2560x1440 with FullScreen ON. Quality settings were on 'Medium' with one exception -- Texture Quality was set to 'High.' vSync and High Detail Strategic View were both OFF. (LONGER bar indicates FASTEST in frames per second.)

X-Plane-32bit - Our Phantom Jet Fighter takes off over the ocean during a thunderstorm. Best settings at 2560x1440. (LONGER bar means FASTER average frames per second)

Unigine's Heaven Benchmark 4.0 is an OpenGL 'real world' benchmark that flies through 26 scenes of a village, a ship, and floating islands applying advanced ambient occlusion, volumetric clouds, and various lighting conditions with refraction. We used Extreme preset for our testing which specifies 1600x900 windowed resolution with 8x Anti-aliasing, Ultra Quality for Shaders and Textures, with Occlusion, Refraction, and Volumetric Shadows enabled. (LONGER means bar means FASTER AVERAGE frames per second.)

INSIGHTS and INFO
1. The EVGA GeForce GTX 680 Mac Edition is the clear winner in the tests featured on this page.

2. The specs show the GTX 680 supporting up to four displays. I've observed Aperture grabbing over 1G of video memory (VRAM) while removing noise from 50 raw images. With only 2G of VRAM, does the GeForce GTX 680 have enough to support the four displays if multiples such pro apps are running? Turns out that the displays themselves only consume about 45MB each. The majority of VRAM is consumed by the apps themselves. One way to track the total consumption of available VRAM during your workflow is with an Apple Developer app called OpenGL Driver Monitor (see Current Free Video Memory parameter).

3. According to EVGA's spec sheet, it is compatible with Mac Pro 'early 2008' or later running OS X 10.8.3 (aka MacPro 3,1 or later). Just as with the Radeon HD 5870 and GeForce GTX 285, it requires two 6-pin PCIe Power feeds. You may have the correct power cables already but a 'fresh' pair is included in the kit along with one DisplayPort to Mini DisplayPort adapter and one DVI to VGA adapter.

CHECK OUT PART TWO...
... where we benchmark using Pro Apps like Cinema 4D, Motion, DaVinci Resolve, After Effects (Ray-traced 3D), and Octane Render.

And Part Three where it goes up against 'alternative' GPUs like the GeForce GTX 580 Classified and GeForce GTX 690.
