NVIDIA just announced that its new Quadro K5000 GPU will be available on Mac Pros, offering 4K display compatibility and support for up to four displays, not to mention 4GB of graphics memory and about 2x faster performance than the Fermi-based Quadro 4000. While the Kepler-powered chip won't actually hit Apple systems till later this year, we got a first look at the K500 on a Mac here at IBC. NVIDIA demoed Adobe After Effects and Premiere Pro CS6 on a Mac Pro with dual K5000 GPUs.
As you'll see in the video below, with 11 streams of 1080p video at 30 fps in Premiere Pro (and one overlay of the NVIDIA logo), GPU acceleration handles the workload seamlessly, letting us add effects in real time without any processing delay. Switching to software rendering mode in the editing program shows a night-and-day difference: video playback is extremely choppy, and processing moves at a crawl. Even with two K5000 chips in this desktop, Premiere Pro utilizes just one, but After Effects takes advantage of both GPUs. In this program, NVIDIA showed us ray-tracing, a computationally intensive 3D imaging feature, which only became available in After Effects with the release of CS6. Like in Premiere Pro, the program runs smoothly enough to let us edit images in real time. Take a look for yourself by heading past the break.
