Cool

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.

OK, more testing just completed on these 2 machines.

1.6 GHz G5 (1.25 GIG's RAM 10.2.7) vs. 1.25 GHz DUAL G4 MDD (1.25 GIG's RAM 10.2.3)

Application used in test : Adobe After Effects 5.5.1 with Nightflight Project file.

Test : Render 10 frames of Nightflight and see how long each machine took to complete this task.

Results :

1.6 GHz G5 - 850 seconds

1.25 GHZ DUAL G4 MDD - 690 seconds

Winner for this test is the DUAL G4 1.25 GHz. In fact the DUAL G4 1.25 MDD is 19% faster at rendering this project file.

Summary : All you graphics people out there who mostly use ADOBE AFTER EFFECTS take care before you consider trading in your DUAL processor G4's for the single processor G5's. The DUAL G4's still have the edge at the moment. A DUAL processor G5 is in need here to beat out the DUAL G4 MDD.

Check out the following link for more results using this project file. Results in the middle of the page.

Yes IF you are doing rendering the dp 1.25 will outperform in the rendering times BUT don't include "all graphics people" because the minute other activities, moving data, assembling etc that use the bandwidth come into play the G5s start to walk away.
Quark, Illustrator, Flash, Indesign etc use little in the way of rendering and really can use the bandwidth and math performance and drive speed.
So I would modify and say video people should consider carefully ( and the multiple buses are a big help for video ) but Graphics users who do NOT need OS9 generally are better off with the enhanced architecture of the G5.
Those using 9 of course the single and dual G4s are bargains. Thanks for the results.

Right now with the exception of the 1.8 ( needs to be single 2 gHz with a better video card ) Apple's tower line up is very good.

What I really meant by my summary comment was that in this ONE particular test I would have to say that a DUAL G5 is the only machine that will beat the DUAL G4 MDD in THIS ONE TEST. I in no way meant to imply that people should not buy the new G5's. In fact I LOVE my shiny new 1.6 GHz G5. It screams along with all the tasks that I've been throwing at it so far. Like I mentioned before and will say again, PANTHER is going to change all the test results anyways. The G5's aren't even running at their full potential on JAGUAR. So yes Dave is correct in that for the moment for people working with video you better buy a DUAL G5 if you want to have more power than a DUAL G4. I will say one more thing in that if you are a professional needing to work at ever faster speeds, than you should always be buying the fatsest MAC available anyways. I only bought the single 1.6 GHz G5 because it's for home use with my audio applications. If I was buying for the office I would insist on a new DUAL G5.

I want to mention that the G5 is quieter than the G4 MDD. It boots faster and applications launch much faster. The graphics are snappier and the hard drives move data at a much higher rate. The fact that it's quieter for me is a big plus because my home office is so small and quiet that the less fan noise I have to listen to all day the better. I'm also very impressed with the speed of the new superdrive that is in the G5. My old DUAL 800 G4 superdrive MAC was a slug and I thought that that would be the same for the G5. NOT SO! These new generation super drives retrieve data from CD's at a very fast rate, I'm impressed.

I don't want to get caught up in numbers (too Late for that) and render times and tit for tat, this computer is better than that. So I'll perform a Final Cut Pro test in a couple of days and maybe that will be the end of the testing. It's weird, but when I perform the tests I want the newer G5 to come out on top because it's new. But the reality of the situation is that each POWERMAC G5 or DUAL G4 is obviously going to perform differently and maybe what it boils down to is this. Utilise whatever tools you have at your disposal and have fun doing your work. Whatever recent POWERMAC your working on is most likely a great experience and personally I upgraded to the new G5 because in the past I always kept my MAC's for too long and they eventually had little to no resale value. So now I upgade about every 10 months. The small loss I take in the wallet is worth it so that I can have the newest MAC at the time of purchase. There's no way to personally rate or graph that kind of data. Owning the latest MAC also comes down to estetics as well. They sure are pretty!

Here is a link that may help explain a few things about the new G5 processor. Check it out.

And don't forget to check out MacDoc web site. He know's his mac's. Dave is friendly and knowledgable to anyone. Especially for any first time MAC buyer's out there I give macdoc my recomendation.

Just another point, you will notice a performance increase with Panther, but you notice another (probably more dramatic) increase with the next versions of all these apps as they become G5 optimized.

Ouch!! Here's a stinger....put a new cat under the hood (courtesy the Green Fairy) of the 1.6 GHz G5 single processor and ran the Adobe After Effects NIGHTFLIGHT test to see how it performed.

Time to render 10 frames - 948 seconds

This is worse than when running the test a couple of days ago with Jaguar. That's a 9% drop in performance , what does this mean..Nothing! After Effects 5.5.1 is not even optimised to take advantage of the new OS X, so we wait and see what Adobe gives us for an updater for After Effects. Aah, the world of testing makes me even more curious.
