Encoding times between i5-2500 & i7-3770K
 

I recently upgraded my CPU from an i5-2500 to an i7-3770K. I am a bit disappointed and mysterfied at the apparent lack of a reduced encoding time from that when I had the i5-2500. I made a little 2min 45 second video with transitions etc as a test peice and found the i5 rendered at 1.2 times real time and the same video with the i7 was only 1.1 times real time. I noticed using Win 7 Task Manager that the CPU was only peaking round 75 to 85% where the i5 was always round 98%. The video was in hi definition and was being rendered to Blu-Ray MPEG2 in Vegas Movie Studio Platinum 12. Can anyone suggest where I might be going wrong?? My desktop system specs as follows:- RAM 8G DDR3 1600mhz, Graphics card Nvidia GE Force GTX560Ti, Motherboard P67A-UD5-B3, OS Win 7 64bit, Western Digital hard drives 7200rpm. Any members encoding times for this setup would interesting to hear about, cheers.
