    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)

    [​IMG]


    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)

    [​IMG]


    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”



    [​IMG]


    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 !

    [​IMG]

    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.

    For ***** & giggles, I'd love to clock my G4 iMac from 2003, but, alas, it's power PC.

    If this is what the current iMac i7 does...I really wanna see what the SB iMac does in a couple months.

    They'll be beasts.

    Damn .. iMac i7 2010 beaten a bit by MBP 2011 .. I'm gonna get myself one of those Sandy Bridge iMac this year. I swear I will :D

    MBP 2011 only use the mobile Sandy Bridge, imagine how good it will when the new iMac using desktop Sandy Bridge, more power than Vin Diesel can handle :p

    27" iMac 2.8 GHz 4 core i7 (late 2009) 6 mins 18 secs @ 38.015854 fps

    Fast enough for me for home use, I can't really see why anyone would really need to chase faster speeds just for the sake of them. Personally I'd have to wait a couple more iMac generations before I considered it was worth upgrading my current iMac.

    AMD 1055T @ 3.8GHz = work: average encoding speed for job is 55.087067 fps. Not bad for a $500 PC. AMD hexcore CPU's kick ass in multi threaded tasks.... single threaded not so much. We should also do an audio encoding test for single thread performance. That's where SB really shines.
    I'm going to do this test on my wifes computer (Core i7 920 @ 4.2GHz) tonight when she isn't using it. It should break 60 fps easily.

    Waiting for the update before I get my first iMac, but I thought for fun I'd run this with my 2007 Macbook, 2.16 GHz Core 2 Duo.

    [16:02:48] macgui: processNewQueueEncode number of passes expected is: 1
    [16:39:41] work: average encoding speed for job is 6.504608 fps

    Time: 36:53 min
    Framerate: 6.50 fps

    Turns out that was no fun at all for my processor.

    I'm gonna run this in a few minutes, just to see how my iMac 27" i7 2009 runs this.

    [16:38:16] work: average encoding speed for job is 42.016090 fps

    i7 2.8GHz - 16GB DDR3 1333 MHz RAM (might be the reason for the slight speed boost)

    Dunno what I'm supposed to divide that from. There's a number of 14315 frames, 14339 and the render actually did 14313 frames.

    So I'm either at ...

    14315 / 42.016090 = 5.678380195142070 = 5m 40.7s
    14339 / 42.016090 = 5.687900357537636 = 5m 41.3s
    14313 / 42.016090 = 5.677586848276458 = 5m 40.7s

    So let's call it 5m 40.7s.

    Can't wait to see an 8 core Sandy Bridge iMac. Especially an i7-2600. Sandy Bridge, clock for clock, is supposed to be 10-20% more efficient at the same speed. The i7-2600 is a 3.4GHz turboing to 3.8GHz. So faster all around, and more efficient.

    GeekBench scores should be around 12K + for them.

    I'm going to put my Mini in the running for the slowest time. :) This is a great idea though, as I'm going to pull the trigger on a Sandy Bridge iMac, so this should be an interesting test to show just how tangible the difference is.

    <sarcasm>
    I'll have my results sometime tomorrow.
    </sarcasm>

    :D

    In case you have signatures hidden, I'm running a 1.83GHz Core 2 Duo Mini with 4GB RAM.

    Prolly take about an hour or so for you.
    I finished mine but I'm looking in the log where the time is.

    Just noticed the OP asked for iMac times. I'll still contribute my Mac Mini time though, if for nothing else but my own use.

    Please forgive my ignorance and/or stupidity but once the encode is complete and I have my average FPS how do I then calculate my total encode time?

    ...:eek:

    I just divided by the frames of work done.
    For mine though I had 3 sets of numbers, so I did math on all 3.

    OK, the time for my Mini is in, and I have to admit, it's much quicker than I expected.

    Average FPS: 9.295321
    Encode Time: 25 minutes, 36 seconds

    Again, this is with a 1.83 GHz Core 2 Duo Mac Mini with 4GB of RAM.
