Adobe CS5: 64-bit, CUDA-Accelerated, And Threaded Performance

Premiere Pro CS4

We wanted to leverage as much of the work done by Chris Angelini in his “Can Your PC Use 24 Processors?” story as possible, so in addition to his custom After Effects load, we also replicated his Premiere Pro work set. Part of this job involved created a custom setting scenario in which the 23.976 FPS default Blu-ray speed (24 FPS in CS5) was doubled to 59.94 FPS. As Chris did, we recorded both the render time as well as the export time with Premiere’s Adobe Media Encoder (AME) in order to assess two key parts of the video workflow process. The single point where our test data replicates Chris’s render and AME times within 20 seconds (980X with 12 threads and HT enabled) confirms that we’re on the same track and working with solid results.

In a workstation setup, Chris didn’t see much positive scaling when moving from the i7 into the Xeon line. Working solely with the i7 and modifying core counts, we see a much more obvious and rewarding progression. Once more, you don’t get as much kick in the move from four cores to six as from two to four, but the benefits of each core increase are clear. Moreover, we see the 10% to 20% benefit from enabling Hyper-Threading that we’ve been expecting all along. Without a doubt, the six-core Intel approach is the way to fly with Premiere Pro CS4.

Unlike our other two Creative Suite apps, Premiere Pro makes much more effective use of all available processor cores, including virtual ones. We don’t see any real breathing room with utilization appear until we hit 12 threads.

    Fermi exceeds at something finally!
    What if I am an ATI user?.
    And Iam an ATI user !!!.

    magpcWhat if I am an ATI user?.And Iam an ATI user !!!.You still get gpu acceleration just not as much =p and it would be a ATI listed on their site just like nvidia it's a limited pool.

    Please increase the size of the legend. It is easy to figure out in this review since it's only two colors, however, if it is more than 2, it is hard to figure out which bar is referring to which score.

    Please consider changing the page drop-down menu to the old school drop-down menus like the other tech blogs like Anandtech and Arstech, etc.

    The interface is a little clumsy and seems to be poorly timed when I try to scroll down the drop-down menu. It often closes when I am trying to scroll to another page. Sometimes, when the page loads, it is hidden by a pop-up word ad.

    However, the article content was strong.

    I have an ATI card and still I have no problem using photoshop CS4 and premiere CS4. The thing with CS5 is that if you can't wait at all, but it is not that really long.

    why cuda and not open-cl?!!

    amazing performance increase !!!!!

    Surely they mean the 2GB memory limit (for Win32 processes)?

    Which is one reason why the Apple Mac version is so popular (Unix/BSD can handle more per process).
  • Why CUDA? Simply 'cause it's a mature technology.

    adiomariwhy cuda and not open-cl?!!
    CUDA preceded Open-Cl. Dev cycles are long and tedious. If you're going to implement something, it'll take time to show up. I honestly hope more developers decide to code for Open Cl.
