AMD Phenom X4 9850 Black Edition Review - Page 6

By Vince Freeman March 27, 2008

TMPGEnc Xpress 4 MPEG-2 Encoding Performance

Since the release of the Intel Yorkfield, we've totally revamped our media encoding tests, upgrading to TMPGEnc Xpress 4, and changing our default video files. TMPGEnc Xpress 4 not only provides real-world video encoding performance results, but also includes a host of specialized CPU support options. The program is full multi-threaded 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 Duo/Extreme mode.

Due to the increasingly high performance of quad core processors, our reference video is now a higher-end, 8-minute AVI file. In our first test, this file is encoded at 720x480 MPEG-2 DVD quality video using TMPGEnc 4 and the encoding time is recorded. The 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 better encoding performance.

Although MPEG2 DVD encoding does not put the most stress on the processors, it's still a very appropriate benchmark for a multimedia desktop. The Phenom X4 9850 posts a very nice time, ahead of the Core 2 Extreme QX6700 and just behind the Phenom 9900 and Core 2 Extreme QX6850. Also, these time gaps may not seem like much, but remember we're only talking about an 8-minute file, and relative positioning is still the most important factor.

TMPGEnc Xpress 4 DivX Encoding Performance

For the next test, we've taken the same video file, and encoded it to DivX (656x336) using TMPGEnc 4. This is about on par with the previous DVD authoring test, but uses a difference 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 results also show the Phenom architecture competing very well against the Core 2. The Phenom 9900 has the fastest encoding time, but the Phenom X4 9850 is not far behind.

TMPGEnc Xpress 4 Windows Media Video Encoding Performance

This time out, 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.

The results in the Windows Media Video encoding test are not as good, and since this benchmark tends to reward both a higher clock speed and additional cores, the Phenom suffers. It's still a good encoding time, but at almost six and a half minutes, the Phenom X4 9850 is not going to be setting any records, and even falls back of the Intel Core 2 Duo.

TMPGEnc Xpress 4 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 really separates the processor classes, and we clearly see the true benefits of a quad core architecture. The Phenom X4 9850 bounces back nicely, and competes very well against the Core 2 Quad Q6600 processor.
