AMD A6-3650 Llano APU Performance Review

LAME MT Audio Encoding and Cinebench R11.5

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.

LAME MT
Audio Conversion and Encoding

In this test, we created our own 223MB WAV file (a hallucinogenic-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.


Audio encoding is most certainly not a strong point for the AMD A6-3650. This test only exercises two cores, so half of the APU's resources remain idle, but even against Intel's dual-core processors, it's not pretty for AMD.

Cinebench R11.5
3D Rendering

Cinebench R11.5 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 and animates 3D scenes 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.

Cinebench performance is a mixed bag. In terms of CPU performance, the A6-3650 falls in somewhere between the Core i3-2100T and i3-2120. Its GPU score, however, is far better than anything Intel can muster and trails only the A8 or Phenom, when the latter is equipped with a Radeon HD 6500 series discrete GPU.
