In the Premiere Pro work area at blogs.adobe.com amooney, a member of the Premiere Pro team, has posted a short info, which says:
There has been a lot of confusion and misinformation recently about how well Premiere Pro CC runs on Apple’s latest professional desktop machine, the new Mac Pro. I’m happy to say that, due to the meant-to-be combination of the Mercury Playback Engine and the immense power of the hardware, you can expect absolutely phenomenal performance.
The abovementioned confusion was the result of Apple’s decision to use ATI GPUs (OpenCL) and Adobe’s software initial lack of support for these. Adobe adapted quickly, but the news on newly supported GPUs within Premiere Pro does not seem to have reached enough CC users – hence the above message. The statement also links to a video recorded by Adobe rep, Dave Helmly, who presents how efficiently PP runs of the new Mac Pro. Dave presents PP performance in different types of workflows. Here’s short info from the video’s description:
In this video Dave Helmly gives you a quick tour of Apple's New Mac Pro running Premiere Pro CC in various workflows including Multi Layer GPU Effects, 4K, Mixed 4K timeline, the power of Dual GPU Exporting vs CPU (software/CPU) , and finally GPU based Debayer for Red RAW R3D files.
And the video itself:
