WB5 Windows Media Encoder 9 & LAME MP3 Encoding Tests
Completing our World Bench testing, we ran a final bout of the Windows Media Encoder 9 module.
This time around the Pentium D 820 showed what its capable of, easily beating all other processors in the list. With Windows Media Encoder being multithreaded, the application can tap the potentional of both cores, giving it an obvious advantage over the single-core comparison sets. Aside from the dual-core aspect, the test also benefitted from Intel's Hyper-Threading technology, as the Pentium 4 630 and 530J demonstrated, with the 2GHz Athlon 64 3200+ dropping into the last spot.
In our custom Lame MP3 encoding test, we converted a 223MB WAV file to the MP3 format. Processing times are recorded below. Shorter times equate to better performance.
Here we see another example of no real benefits of dual-core processing. In fact, we found the Athlon 64 3200+ completed the test in the shortest amount of time, while the Pentium D 820 took the longest. From the Pentium perspective, the picture implies raw clockspeed and a higher IPC as the key differentiating factor overall.
