Avidemux + x264

Our test videos use H.264 encoding exclusively. To start with, we use Avidemux version 2.5.1 to compress a 1920x1080 HD video file via the x264 codec at intermediary quality.

The Core i5-661 offers similar performance levels to the Q8200 and is a little slower than the Athlon II X4 620. The Core i3s fall between the dual and quad core S775s and are on a par with the Athlon II X3s.
MainConcept Reference + H.264/AVC Pro

For this second H.264 encoding we use MainConcept Reference and its H.264/AVC Pro codec on “High”, still with the same video.

The results are better than in Avidemux for the new dual core 32nms. The Core i5-661 is on a level with the Q9550 and is between the Athlon II X4 620 and 630.
