AMD Athlon 64 X2 3800+
We continued testing the new AMD Athlon 64 X2 3800+ with a benchmark based on Windows Media Encoder 9. PC WorldBench 5's Windows Media Encoding test reports encoding times in seconds, and like the tests on the previous page, lower times indicate better performance here.

The AMD Athlon 64 X2 3800+ proved to be a good performer in the Windows Media Encoder test as well. Here, the X2 3800+ too about 46 seconds longer to complete the encoding process than the Athlon 64 4800+, but it finished the process over a minute faster than the 2.8GHz Pentium D 820.

In our custom Lame MP3 encoding test, we convert a large WAV file to the MP3 format, which is a very popular scenario that many end users work with on a day-to-day basis, to provide portability and storage of their digital audio content. In this test, we created our own 223MB WAV file (a never-ending Grateful Dead jam) and converted it to the MP3 format. Processing times are recorded below. Once again, shorter times equate to better performance.
With its 400MHz clock speed advantage, and additional megabyte of cache, the Athlon 64 X2 3800+ had no trouble outpacing the Athlon 64 X2 3800+ in our custom LAME MP3 encoding benchmark, besting the 3800+ by roughly 20 seconds. The Pentium D 820, however, didn't fare so well. It took 12 seconds longer than the Athlon 64 X2 3800+ to encode the exact same file.
