And It gets even beter! I'd did it once again first thing after fresh start:

1 min 14.5 sec

Those new imacs are really fast, i cant wait untill 2 GB DDR2 get afortable!
 
man...., you've just got me tempted in getting that 1 gig stick...... :D

i'd just wish i had gotten the 20" instead....
 
Well...look at this:


(cliffrouse11bas)
New Imac G5 with Isight 20in 2.1ghz with 1.5gb Ram

1:39
1:37 after a fresh restart.


The 20" 2.1 seem to be slower than the 17" 1.9?
strange isn't it?
 
I joined this forum just because of this... cool test!

Anyway here's the results from my lousy PC laptop. I know its not a mac but it might give you an idea how the intel machines will do...

Pentium M 1.86 ghz
512 mb Ram
1:39

I also ran it with the processor set to 780 mhz and got a time of 3:51... quite a difference.

And on an apple:

Quad Core G5
1.5 gb ram
19 sec

Will the intel apples beat that?
 
my 12" pbook with 1.25 Gb of RAM (for this test i dedicated 100% to ps):

photoshop 7.0: 168.3 sec
photoshop CS: 136.1 sec

what a difference between 7.0 and CS!

Well I've shaved my dual 3Ghz xeon box down to 29 seconds at default clock speed and 26 seconds at 3.33Ghz. I'd suspect that a dual 3.6 xeons will do it in about 24 seconds. Now seeing that dual core xeons are out, I'd be very tempted to say that having dual dualcore cpus will bring that down for sure to under 17 seconds.

Again I'm only basing this on my experiences with my dual 3Ghz single core xeons. Also I'm not sure what kind of intel CPU apple will go with but I'd hope in the high end boxes, they will use dual core xeons and hopefully two of them :)

Dual core Xeon MPs are only available in 3.0GHz to my knowledge. :confused:
 
52.5 secs

But wait!!!! Flicking around in this thread, I found references to a processor performance setting...one which I'd never heard of before. So I found it, set it to "Highest" Then I got....

43.2 secs Almost a 10 second improvement! Sweet!

Learn something new every day! Sometimes a couple of things!

Right... but that should be more than enough power. My dual xeons pull off 29 seconds at 3Ghz so I'd hope that quads will easily hit half of that....

If I disable one cpu on my xeon box, my time actually goes up more than double. Its almost like the gain is something like 2.5x.... unless its the combination of the two cpus together AND hyperthreading that work their magic.

Intel says that dual core xeons give a performace increase of approx 50% compared to single core http://news.zdnet.co.uk/hardware/chips/0,39020354,39235135,00.htm if I understand that correctly. Should be 19 secs with 2 dual core Xeons, then.
 
120 seconds.

2min 3sec

20" 2Ghz iMac G5 1.5Gb ram
i also had mail safari ichat addressbook itunes and preview open with an additional 17" lcd hooked up for spanning if that makes a diff. i am gonna try it on my 266mhz iMac now :D

I tested the following machines after fresh restart, with default 75% for PS.

2 GHZ Revision B iMac G5, 1.5 GB RAM, Tiger, CS2: 2:24

1 GHZ dual-boot eMac, 1 GB RAM, Tiger, CS2: 3:22

400 MHZ iMac DV, 288 MB RAM, 7500 RPM–8 MB cache HD, Tiger, CS: 9:42

233 Mhz Rev A Bondi iMac, 384 MB RAM, 7500 RPM–8 MB cache HD, Panther, CS2: 14:02

One thing that puzzles me is that I'm repeatedly getting 2:24-2:25 on the 2 Ghz iMac,
which is a good bit slower than the other 2 GHZ revision B iMac results posted so far.

Any ideas? :confused: :( :confused:
 
DC 2.3 = 40.5s

39.9s

PShop CS (V8.0) DC 2.3Ghz
2.5Gb RAM
OSX 10.4.3

(hand timed pretty consistent: 40.57, 40.48, 40.52 & processor set to
highest: 40.25, 40.34, 40.23)

EDIT: using the Adobe Multiprocessor Support updated extension gave a small improvement clocking 39.9x over several attempts. Yes I am obsessed with this PS benchmark!
