When encoding with main concept's h264, from within TE4, SSE4 allowed the E7400 to match the encoding performance of the phenom.
In test after test, comparing a phenom 9500 (easily the crappiest quad core ever made and one of the top 10 biggest disappointments from a cpu stand point) to an E7400, when encoding mpeg-2, with SSE4, it was actually faster, by a convincing margin, than the phenom 9500. TE4 was also the first video related app, and to this day one of the few, to support SSE4 and what a difference that made. TMPG 4 Express was the first to support any type of CUDA acceleration, albeit only for mpeg-2 decoding and filtering, but if you had a high bit rate 1080i mpeg-2, that you wanted to de-interlace and convert to h264, it was worth it's weight in gold. TMPGEnc Video Mastering Works 5, what a freaken name! For those of you that have been living under a rock or just couldn't give a flying 'f' bomb, that is the name of the successor to TMPG 4 Express. Note: i posted this quasi review over at the video help forms, thought maybe some here would find it useful:
