    AMD Phenom II X4 940 BE Review
    By Vince Freeman :  January 9, 2009

    TMPGEnc 4.0 Xpress MPEG-2 Encoding Performance

    For our media encoding tests we use TMPGEnc 4.0 Xpress and a selection of high-end video files. TMPGEnc 4.0 Xpress not only provides real-world video encoding performance results, but also includes a host of specialized CPU support options. The program is fully multi-threaded, outlining the number of physical and logical cores, and supports virtually all CPU multimedia features such as MMX/MMX-2, SSE/SSE2/SSE3, 3D Now!/Enhanced 3D Now!, along with a Core 2 mode.

    In our first test, our 8-minute AVI file is encoded at 720x480 MPEG-2 DVD quality video using TMPGEnc 4.0 and the encoding time is recorded. The results are expressed in the form of time elapsed (minutes: seconds) and unlike many of our other benchmarks, a smaller bar denotes less time taken, and therefore better encoding performance.

    Although MPEG2 DVD encoding is not the most difficult test in our suite, the Phenom II X4 processors still show noticeable gains over their Phenom X4 counterparts, and the Phenom II X4 940 manages to break the 2-minute barrier. This is significant, as that pushes it by even the Core 2 Extreme QX9650 and into Core i7 territory.

    TMPGEnc 4.0 Xpress DivX Encoding Performance

    For the next test, we've taken the same video file, and encoded it to DivX (672x352) using TMPGEnc 4. This is about on par with the previous DVD authoring test, but uses a different codec. The performance results are expressed in the form of time elapsed (minutes: seconds) and as with the MPEG-2 results, a smaller bar denotes less time taken, and therefore higher performance.

    The DivX encoding test results are also very impressive, and the Phenom II X4 940 is once again posting faster times than the QX9650, and pushing closer to the Core i7-920. As in all our tests, the gaps may seem small, but try extrapolating the 8-minute video to a full 2-hour file.

    TMPGEnc 4.0 Xpress Windows Media Video Encoding Performance

    Now we're switching to Windows Media Video (WMV), and encoding the same video file as a 672x352 .wmv file. As with the previous tests, these are time-based and a smaller bar denotes higher performance.

    Under Vista, our Windows Media Video encoding testing is more consistent in terms of multi-threading, and unlike with Windows XP, the fastest quad cores consistently showed the best encoding times. The Phenom II X4 940 completes a three-peat here, and not only outperforms the QX9650, but comes within a hair of catching the Core i7-920.

    TMPGEnc 4.0 Xpress High-Definition Video Encoding Performance

    Our final media-encoding test ups the ante considerably, this time forcing the processors to handle a high-definition video job, taking the end resolution to 1440x1080, with a 25000 Kb/s CBR. This test forces many systems to their literal knees, and is certainly not for the faint of heart.

    The high-def video benchmarking can really separate the processor classes, and it completes the run for the flagship Phenom II X4 940, which again posts the fastest non-Core i7 encoding time.
