It's time to put the new G5's to the test. Real world user tests. Not graphs and industry B.S.
I just bought (from Dave at MacDoc,Thanks! Dave) my G5 1.6 GHz powermac and I've completed one test on it against a DUAL 1.25 GHz MDD.
I did a test so far with PROPELLERHEADS REASON as follows:
G5 1.6 GHz with 1.25 GIG's RAM OS 10.2.7 vs. DUAL 1.25 GHz MDD with 1.25 GIG's of RAM OS 10.2.3
REASON 2.5 loaded in both machines and preferences set the exact same on both computers. Loaded in the same project file for both machines and waited to see the results.
G5 1.6 maxed out to 100% processor usage many times during playback. But it played back song without any stopping or stuttering or slowing down of tempo. G4 DUAL 1.25 maxed out to 50%/50% on processors almost all the time during playback. Playback on the G4 stuttered and the tempo of song would flutter down & then go back up depending on the load the song was taking at that given moment.
Summary : The single G5 1.6 GHz machine came out on top for this real world test. I don't want to mislead anyone though so I have to also say that the DUAL 1.25 G4 didn't do that bad. It played back most of the project song fine except in areas where heavy effects where used then the G4 processors would max out and playback suffered and project song would slow down and audio stuttering would occour. So if you were depending on the G4 to make you money in this test scenerio, you'd be lining up to buy a new G5 to get the job done.
The important piece of the puzzle that people have to know is this : Most audio applications are not designed to utilize dual processors. That's why the single 1.6 GHz G5 beat out a DUAL 1.25 GHz MDD for this particular applcation.
Also, when Apple releases OS X PANTHER in the next month or so the G5's should see a significant boost in overall CPU horsepower. PANTHER was designed with the G5's architecture in mind whereas JAGUAR was designed more for the G4 architecture.
Here is the Xbench score my G5 received when I ran it 2 days ago :
148.76 PowerPC 970 @ 1.60 GHz 2003-10-01 01:01:29
Check out the Xbench web site and look at the comparison pages to get an idea of what the scores mean relative to other models of powermacs. http://ladd.dyndns.org/xbench/
If the ehmac community has time and people can put new G5's up against the last generation of G4's post your results here. It will help people understand if G5's are right for them or not. I'm going to do an Adobe After effects test tomorrow with the same machines and will post the results.
