LAME MT and Cinebench

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. Shorter times equate to better performance.

Not much to see here. The 890GX-based motherbaords performed right on par with the 785G in the LAME MT encoding benchmark. If you want to nit-pick, the 890GX boards were slightly faster in the multi-threaded test, but benchmarks doesn't have the granularity in its results to show sub-1-second differences. So, even though that graphs have a 1 second advantage for the 890GX, the different could be somewhat less than 1 second, and most likely are.

Cinebench R10
3D Rendering

Cinebench R10 is an OpenGL 3D rendering performance test based on Cinema 4D from Maxon. Cinema 4D is a 3D rendering and animation tool suite used by 3D animation houses and producers like Sony Animation and many others.  It's very demanding of system processor resources and is an excellent gauge of pure computational throughput.

This is a multi-threaded, multi-processor aware benchmark that renders a single 3D scene and tracks the length of the entire process. The rate at which each test system was able to render the entire scene is represented in the graph below.

All of the AMD-based systems performed similarly in the single-threaded Cinebench test, but the 890GX boards had a slight edge in the multi-threaded test. The deltas separating the AMD platforms isn't huge, but the 890GX based boards from Gigabyte and Asus had an edge nonetheless.
