AMD Phenom X4 9350e and 9950 BE Debut

LAME MT and Kribibench v1.1

In our custom LAME MT MP3 encoding test, we convert a large WAV file to the MP3 format, which is a popular scenario that many end users work with on a day-to-day basis to provide portability and storage of their digital audio content.  LAME is an open-source mid to high bit-rate and VBR (variable bit rate) MP3 audio encoder that is used widely around the world in a multitude of third party applications.

Audio Encoding

In this test, we created our own 223MB WAV file (a hallucinogenically-induced Grateful Dead jam) and converted it to the MP3 format using the multi-thread capable LAME MT application in single and multi-thread modes. Processing times are recorded below, listed in seconds. Once again, shorter times equate to better performance.

Our custom LAME MT benchmark heavily favored the Intel processors, whether running in single- or multi-threaded mode. The Phenom X4 Black Edition put up the best numbers of any AMD processor, as expected, and the much lower-clocked 9350e trailed by a decent margin.

Kribibench v1.1
CPU-Bound 3D Rendering

For this next batch of tests, we ran Kribibench v1.1, a 3D rendering benchmark produced by the folks at Adept Development.  Kribibench is an SSE aware software renderer where a 3D model is rendered and animated by the host CPU and the average frame rate is reported.  We used two of the included models with this benchmark: a "Sponge Explode" model consisting of over 19.2 million polygons and the test suite's "Ultra" model that is comprised of over 16 billion polys.

The Phenom X4 9950 Black Edition performed well in the Kribibench tests, besting the Core 2 Quad Q6600.  The Phenom X4 9950e finished somewhere in between the triple-core 8750 and higher-clocked Phenom 9600.
