Adobe Premiere Pro is unique among Adobe pro apps in that it supports acceleration of video effects by graphics processing units (GPUs) that support either CUDA or OpenCL -- unlike some pro apps that support one or the other. So we set out to answer questions like, "Which graphics card does the best job of rendering these effects?" and "Do I need a Mac Pro or will a 2012 Apple laptop render these effects just as fast?"
GPU ACCELERATED VIDEO EFFECT: DIRECTIONAL BLUR
LOWEST number equals fastest time in seconds.
GPU ACCELERATED VIDEO EFFECT: FAST COLOR CORRECTION
LOWEST number equals fastest time in seconds.

INSIGHTS and ADVICE
Every Mac with an NVIDIA GPU and CUDA support rendered Premiere Pro CS6 GPU accelerated video effects in the shortest time. But the AMD GPUs were not "slouches." On the other hand, the MacBook Airs with the Intel HD 3000 and 4000 integrated GPU were slow.
The 2012 Retina MacBook Pro's GeForce GT 650M rendered a collection of five GPU accelerated video effects an average of 21% faster than the Mac Pro with Radeon HD 5870. On the other hand, the Mac Pro with Quadro 4000 rendered the same five effects an average of 27% faster than the Retina MacBook Pro with GeForce GT 650M. You could say the Retina MacBook Pro was in the middle of the "pack."
What about video effects that are NOT CUDA or OpenCL accelerated? We included Unsharp Mask as an example of a video effect that leans on the CPU rather than GPU. In that case, the 6-core Mac Pro we used in the test rendered that effect 30% faster than the fastest 2012 MacBook Pro. However the Retina MacBook Pro rendered Unsharp Mask 54% faster than the fastest 2012 MacBook Air.
So is the 2012 MacBook Pro equal to the 2010 Mac Pro as a Premiere Pro platform? It depends on what functions you use most and what GPU you are sporting. Taking combined CPU and GPU performance into consideration, the RMBP is NOT the equal of the 2010 (or 2012 'speed bump') Mac Pro -- especially if you have a high-end NVIDIA GPU. It doesn't mean using a MacBook Pro is a bad idea. Just not equal.
As for the 'mid 2012' MacBook Air top model (2.0GHz Core i7), it took and average of three times longer than the 2012 Retina MacBook Pro to render a collection of five video effects in Premiere Pro. You could use the MBA to run Premiere Pro but it would be a big step down from both the Mac Pro and MacBook Pro.
ALTERNATIVE GPUS
As you can see, we included the Radeon HD 6870, GeForce GTX 570, and GeForce GTX 580 in the mix. The samples we used have been flashed with firmware to support both OS X and Windows. They are NOT available from the Apple Store and you can't just order them from Amazon. They can be purchased from special sources like MacVidCards eBay Store -- who supplied our test samples. Another source for replacement GPUs like the Radeon HD 4870, Quadro FX 4500, and GeForce GTX 285 is the AppleMacanix eBay store.
