    Athlon 64 FX-62 & Athlon 64 X2 5000+ Processor Review
    By Vince Freeman :  May 23, 2006

    TMPGEnc Xpress 3.0 MPEG-1 Encoding Performance

    TMPGEnc Xpress 3.0 is a new revision to this popular MPEG encoder, and a program that not only provides real-world MPEG performance results, but also includes a host of specialized CPU support options. The program supports virtually all CPU multimedia features such as MMX/MMX-2, SSE/SSE2/SSE3, 3DNow!, and even support for dual core and Hyper-Threading technologies.

    For the following test, we've taken a high-end, 3-minute AVI file, and then encoded it to MPEG-1 using TMPGEnc. The test results are expressed in the form of time elapsed (minutes: seconds) and unlike our other benchmarks, a smaller bar denotes less time taken, and therefore higher performance.

    Now that we're concentrating exclusively on dual core performance, the media encoding results have moved much closer together, as even an entry-level dual core processor can outperform a high-end single core model in multi-threaded tests like this. Even so, the chart does have some separation, with the Athlon 64 FX-62 posting the top score, and the entire AMD line outpacing the Intel competition. MPEG-1 encoding is more a pure processing test, so the DDR2 vs. DDR memory format has no effect.

    TMPGEnc Xpress 3.0 MPEG-2 Encoding Performance

    For the next test, we've taken the same high-end, 3-minute AVI file, and encoded it to MPEG-2 using TMPGEnc Express 3.0. This is more stressful on the system than our previous MPEG-1 encoding, and is the standard for DVD authoring. The performance results are expressed in the form of time elapsed (minutes: seconds) and as with the MPEG-1 results, a smaller bar denotes less time taken, and therefore higher performance.

    MPEG-2 encoding is much a tougher test for our dual core processors, and this time, we have the Pentium EE 955 coming up and snatching victory from the Athlon 64 FX-62. Sure, it's an extremely slim win, but it does show that the Pentium D has some definite legs in the multimedia area, and that Hyper-Threading can yield benefits with some multi-threaded software.

    XMPEG DivX 6.1 Encoding Performance

    Along with standard MPEG tests, we also use a few different media encoding tests, such as XMPEG and its DivX encoding benchmark test. The same 3 minute video file is used, and the time to encode the first 5K+ frames is displayed in the chart below. As with the previous encoding tests, these are time-based and a smaller bar denotes higher performance. We have also upgraded to the latest DivX 6.1 codec, which features new optimizations for dual processor (SMP), dual core, and Hyper-Threading-enabled systems.

    The XMPEG DivX encoding times show the Athlon 64 FX-62 in the lead, and with a decided AMD advantage throughout the chart. This time the Socket 939 models do show a slight performance advantage compared to the new Socket AM2 processors, and the very latest versions of XMPEG and DivX are certainly not kind of Hyper-Threading and the Pentium DD 955.

    Windows Media Encoder 9 Performance

    Our last multimedia test measures basic Windows Media Encoder performance using the 3-minute DivX file we produced above, and using the Windows Media Encoder 9 to convert it into .wmv format. WME 9 offers support for multi-threading and CPU optimizations, which makes it another great media encoding test for our high-end processors.

    The Windows Media Encoder 9 benchmark results show the same basic breakdown, but this time the DDR2-equipped AM2 processors post slightly higher scores than their 939-pin, DDR-400 brethren. We also see the HT-enabled Pentium EE 955 taking a trip down the performance ladder, and it really seems that the newest APIs are tuned for dual core performance, almost at the expense of Hyper-Threading.
