We began our performance tests by looking at processor-side performance.
We used Cinebench version R11.5 to measure 3D rendering performance. To recap, the software uses the Cinema 4D rendering engine.
[ Monothreaded ] [ Multithreaded ]
At equal clocks, our Core i3 Ivy Bridge does better than the Sandy Bridge model, by 5% in monothreaded mode and 3.4% in multithreaded mode.
Staxrip - x264 b2197
Moving frontend, we used Staxrip to transcode a scene from Avatar via x264 in build 2197. We carried out a medium type 2 pass encoding on a 720p source, re-encoded at a bitrate of 6 Mbits/s. To recap, the second pass is the one that benefits most from multithreading.
[ 1st pass ] [ 2nd pass ]
Compared to its Sandy Bridge clone, the Ivy Bridge model has an 8.8% advantage on the second pass. This makes the Core i3 Ivy Bridge faster than the quad-core A10-4600M Trinity in this test.
Visual Studio 2011 beta
We went for the 2011 beta version of Visual Studio. We compiled the latest version (1.7.4) of the source code of the 3D Obre engine (examples included). Parallel compilation was activated for each project in VS.
The Core i3 Ivy Bridge has around a 4% gain over its predecessor. The Turbo mode of the Core i5s still represents a significant advantage here.
