That benefit goes only so far, though: Adobe has qualified just five graphics cards for use with Premiere Pro–all of which use nVidia’s CUDA technology. The company says that Premiere Pro can “solve many computational problems in a fraction of the time a CPU would take to perform the same task” and thus can render HD video much more quickly–freeing your CPU to handle “background tasks.” If I were Intel, I’d feel insulted by that. One of the benefits of Premiere Pro CS5 is that Adobe is continuing the trend of using GPU power that it began with After Effects a couple of versions ago. Only when I started adding several tracks of HD clips and effects did Premiere start gobbling RAM the highest amount I saw was about 3.5GB. However, with only a simple, single-track project open, Premiere used merely 214MB of RAM–it did not take up the entire 6.5GB, and my system ran perfectly well with several other applications open.
On my 8GB system, the default setup reserved 6.5GB for Premiere and 1.5GB for everything else. However, I had none of the RAM-related problems I’ve occasionally encountered with Premiere Pro CS4–none of the slow reading and writing of data to the hard drive instead of to RAM, fewer playback and timeline scrubbing hesitations, and generally smoother operation overall.Īs with the 64-bit Photoshop, Premiere Pro requires that you allocate RAM manually–up to a maximum of 128GB. Relying on CPU power, Premiere Pro CS5 didn’t render any more quickly than Premiere Pro CS4 did. When I installed a beta version of Creative Suite 5 on my test system, a dual-Xeon workstation running Windows 7 64-bit with 8GB of RAM, I did not notice a substantial improvement in rendering speed–but then, my workstation doesn’t have one of the approved graphics cards. On a 32-bit system, once all your startup programs load, you may have little left over to run memory-intensive applications. The 32-bit versions of Windows have been squeezing users: Those OSs can recognize only 4GB of RAM at most, even as applications and Windows itself have come to demand ever-increasing amounts of RAM. If you have one of a very select (and expensive) group of graphics cards, the application will greatly speed up rendering and real-time playback, and leave your computer’s CPU to handle more-mundane tasks. In addition to being 64-bit-aware, Premiere Pro CS5 relies heavily on GPU processing. With the new Adobe Premiere Pro CS5 ($799 stand-alone, $1299 as part of Creative Suite 5 Design Standard prices as of April 12, 2010), though, you’ll have all the components necessary to make even high-definition video editing fly. You may have all the elements of a great video-editing setup, but for one thing: a video-editing application that can take advantage of all that inexpensive hardware. Big, beautiful LCD monitors? Cheap, cheap, cheap.
