TMPGEnc 4.0 XPress
The fourth version of this MPEG-2 encoder integrates a several optimizations for the Core 2 and improves performances by approximately 5%. For this test, we encode a 10 minute 16 second DV file to MPEG-2 format in 720x576 with an average bitrate of 4500 Kbits in two paths. The video preview display is activated during this test and the DV file is decoded via a Mainconcept codec, which is faster than decoding in TMPGEnc.
Improvements to SSE units bear their fruit here with no less than a 35.7% gain between K8 and K10 with the same number of cores. For this reason, here the Phenom 9600 is relatively close to the Q6600 though just slightly behind.
VirtualDub & DiVX 6.7
We now use the version 1.7.6 of VirtualDub and the version 6.7 of DiVX which has SSE4 optimizations. We encode the same video source as with TMPGEnc in Fast recompress mode and with the DiVX 6.7 codec in one path with an average bitrate of 1500 Kbits /s, highest quality encoding performance, and Experimental SSE4 full search activated in SSE4 or SSE2 mode. The video preview mode is activated during this test.
In DiVX encoding, the Phenom 9600 and Q6600 are even closer with AMD’s quad core being at 98.2% of the performances of Intel’s quad core. There is a 26.5% gain between K8 and K10.
