It's Benchmark Time for iMac owners ! *Updated with results*

that original mac pro holds up pretty well, doesn't it? I mean, it's not the best by a long shot, but it's 5 years old!
 
Dang the highest iMac is a beast! According to that picture and a little guessing the 27" Quad i7 can do stuff 7x faster than my early 08 Macbook.
I'm sold.
 
That 2009 MBP 2.66 appears to be wrong at first glance and second....

Rough guesstimates should be Average FPS x Time = Total frames

That 2009 MBP @ 14.1 FPS and 9:56s but:

2007 iMac has 13.1 FPS and 15:XX

2008 iMac has 15.4 FPS and 15:30s

Therefore these iMacs contradict themselves but within a margin of error but in my rough late-night math, that 2009 MBP is way off ~ 30-40%
 
OK, I know that this is the standard bigbuckbunny test but why is it the standard?

Most users are going to be converting from standard def DVD MPEG-2 or HD Blu-Ray MPEG-2, VC-1, or H.264

When is the average user ever going to use a simple profile 1080p mp4 in an AVI container? Who encodes that way and what devices play it back? DVD, PS3, Xbox360, Blu-Ray?

I'm asking because I have no idea and I've never seen more than 720p Simple Profile in an AVI, and I didn't know what could play it.

I just think that these benchmarks are useless in comparison to real scenarios but they are "ok" for comparing machines.

I'd rather see...
first 3 chapters of "Caddyshack" DVD takes x minutes @ yy FPS

Consistency.

Not everyone's DVD drive is the same.
Not everyone has Caddyshack on DVD.

I think the main reason for the 1080 is to really stress the machines. Not in a folding@home super unit time sort of way. But a 5-10 minute benchmark is quick an smooths out the little inconsistencies in doing repeated tests.

What are the specs of the computer?
Click to expand...

EVGA SR-2, 2x Xeon 5650 running at 3.78 GHz on air, 24GB RAM, Lian-Li PC-P80, OSX 10.6.7 boot disc Mushkin (Sandforce) 240GB, Win 7 Ult 64bit boot disc Intel G2 160 GB, 9 x 2TB (Caviar Black, Hitachi, F4), Blu-Ray writer, Corsair AX1200 W PS, MSI GTX480 (overclocked).

Geekbench >27K http://browse.geekbench.ca/geekbench2/view/281305

I think that with some fine-tuning (getting rid of Sophos, Little Snitch and other programs) the fps can be pushed to >100.
 
2009 Mac Pro 8 core 2.26ghz - 4:29 at 53.6fps

16GB of RAM. CPU's were never 100% taxed. Looks like it didn't use hyperthreading very well. Looks like CPU utilization averaged around 50%. I'd see it jump from 39% to 88% and then back down again, but never a constant 80%+ utilization or anything.

So, a bit slower than the new 2011 iMac, but I got my Mac Pro for a good price recently, so I'm still very happy.

imy experience is that an SSD does not make any difference what so ever
botelneck is the processor only. I have 2 minis with sthe same processor and different graphic cards, the slower one has a small GPU and a 5400 drive the faster one the same core2duo 2.0 Ghz but a better GPU and a 400$ SSD, framerate is exactly the same. framerate is even the same if source/destination is on the external drive on the airport extreme. So the drives do not play any role
