Hi everyone, Our buddies with Macbook Pro’s are having lots of fun benching their latest and greatest laptops with Sandy Bridge processors. There is a great thread by acedickson right here: http://forums.macrumors.com/showthread.php?t=1111126 I bought my iMac 24 Inch alu (model 7,1) in November 2007 and I feel it is getting a bit old, especially for Handbrake encodes. So, in order to give us some kind of an idea as to where our current (and older) iMacs stand in terms of performance, I propose that we run the same benchmark. Step 1: Download Handbrake The link is here: http://handbrake.fr/downloads.php Click on Download (Intel 64bit) Step 2: Download a movie called “Big Buck Bunny”. The link is here: http://www.bigbuckbunny.org/index.php/download/ Make sure you select the right movie (1920x1080 MP4) Step 3: Set up Handbrake log Open up Handbrake, open preferences, select Advanced, then click on “put individual encode logs in same location as movie” Step 4: Select Handbrake Apple TV2 Preset (it's the only quality setting you change !!!) Open up Handbrake, click on “source”, select the file named big_buck_bunny_1080p_surround.avi, select the Apple TV 2 preset, add to queue, then start ! The end result The file will encode and after it’s finished you will go into your encode log Mine was called big_buck_bunny_1080p_surround 2011-03-15 21-46-48.txt You will find the average frames per second in this segment (do a search in textedit) [22:02:12] work: average encoding speed for job is 13.115541 fps You have your FPS. You will then need to calculate your total encode time. [21:46:48] macgui: Rip: Pending queue count is 1 [22:02:12] work: average encoding speed for job is 13.115541 fps My 2007 iMac 24/2.4GHz has run this encode in 15 minutes flat. Let's see the benches while we wait for our Sandy Bridge iMacs ! BENCHMARK RESULTS Thanks François PS: If someone has a suggestion to make on the above please do so! PS2: For those for are holding off from buying a current top-end iMac, just look at the results compiled in the Macbook Pro thread. Similar speed to the Sandy Bridge Macbook Pros.
