Intel Core i7-3720QM Ivy Bridge Mobile Review
Rendering and Media Encoding: Cinebench and LAME MT
Cinebench R11.5 is a
3D rendering performance test based on Cinema 4D from Maxon. Cinema 4D
is a 3D rendering and animation tool suite used by 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.

In Cinebench, the Ivy Bridge Core i7-3720QM processor's OpenGL graphics score is almost 2X that of the Core i7-2820QM, making good initially on Intel's graphics performance claims. In terms of CPU, Ivy Bridge boasts an 18% edge over the fastest Sandy Bridge score.
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. In this test, we created
our own 223MB WAV file and convert 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.
