Make sure you use the Cinebench G5 beta, your single render score is too low, it must be an error...
 
these are my cinebenchand xbench score on my 20"imac 1.8ghz 1024mb ram. Anyone tell me if these results are anygood? thanks

Actually your mistaken

Bluefusion said:
Nope. There is no "Automatic" setting for Energy Saver on desktop machines--what would it be used for? No battery, thus, no energy conservation system. You control system sleep and display sleep, that's it.

So this score is a little odd.

Actually Bluefusion, the new iMac G5 does have an energy conservation system. Yep thats right. And yes you can change the processor speed from Automatic to Highest. You should knows your facts before making blanket statements like this one. The reason for this is that at a lower speed the computer runs quieter when the processor is at full speed it makes some noticeable noise but is about 28% faster. Read the 100th issue of MacAddict magazine if you want the details.

Those OpenGL scores are extremely low. You probably could not find any model PC made in the last four years that scored that low.

Try all the Dells made...ever...that don't have dedicated graphics cards (i.e. most of them). They absolutely suck at everything. You have to get their high end systems in order to get a graphics card. A homebuilt PC of course with a non -MX line card (or the ATi equivalent) certainly makes your statement true. I think even a Radeon 9000 can pull better OpenGL scores, but much of that is driver-dependent.
 
weak video ram?

It seems to me that the main downfall in the iMac G5 lies in the non-upgradable 64mb video card. Considering one of the main functions I want is video editing, I think I will wait until the next round of upgrades, hoping for a video card upgrade or at least an option to upgrade like every other model mac makes. It's frustrating that I just can't buy what I want. Does anyone out there have some experience with editing with the 64mb card. Am I overreacting or is it enough for this task?
 
My iMac has the same Cinebench score as my P4 2.4ghz laptop. It was a bit disappointing but its the Mac experience that counts.

It's quite clear that the iMac G5 is on a par with a DP G4 1.42, both the cinebench and xbench results confirm this. This is a fantastic result. A 20" iMac with a 250GB HDD and maxed out ram will be a formidable machine and is likely to outrun any G4 system.
Click to expand...

Yeah! The iMac G5 1.8 is fast, I tested some Final Cut Pro Edits and Renders with it and is the same speed as a Dual G4 1.42 , with the iMac you even have some advantages with other apps that only use single procs, its even faster when using it for DVD Studio Pro 3 interface and creating the DVD Layout. . .
Cool Stuff. . . Not a bad choice for a iMac G5, I'm thinking about buying one for a extra DVD creations station and maybe replacing my Dual G4 1.25 with one.

Just remember that Cinebench is still a Beta Version for the G5, and is not as optimized as the windows version. . . Even with the same GHZ and Graphic card the Mac comes in slower, but when I benchmarked a GAME the mac was the same speed as the PC. How Strange it was. . . Even when rendering in Lightwave 3D 7.5 it was a little faster, but only 7 seconds, but the interface was faster on the PC, about a third faster in the Open GL. I called Newtek, and the PC Version is more optimized than the Mac Version. Most Programs have better optimiztion than the Mac Version, It takes some time for these changes to take place on the MAC side, but when it does it is worth the wait. . . Just look at what FCP can do with over 7 Layers of Uncompress SD Video in real time with no accel. video card, just a scsi raid, FCP & a G5 computer is all that is needed. To have fun editing in record time !!!

You are over reacting big time. FCP doesn't use the graphic card that much, the only apps that use the graphic card are games, and 3D apps with Open GL thats it, you will be fine with editing video. I am a video editor professional and have used FCP since Version 1.0. Even if you use Dual Monitors you only need 32mbs per screen, a total of 64mbs for Dual screens in Mac OSX. If you use OS 9 you only need 16mbs per screen. The iMac G5 1.8 is just as fast as a Dual G4 1.42 in FCP, the G5 does very well in performing editing tasks even a single proc. is faster in editing, you will notice that the interface will perform much faster than a G4 and even a Dual G4, the interface only uses one proc. rendering use two proc. but the 1.8 G5 does better than one might think against a Dual G4.
 
Yikes is this thread still going?

There are already lots of results both here and at barefeats... but as before, remember on the iMac G5 to:

* set energy saving's CPU to "highest"
* quit all other apps
* don't touch keyboard or move mouse during the benchmark
* you can even hide the dock so dock computation (bouncing, magnification) doesn't affect results.

That said, the darn thing is too noisy at "highest", so many owners should be doing 'real world' benching at CPU "automatic". I myself will put it to 'highest' only when I'm doing something computationally intensive, or gaming, but have it on automatic almost all of the time. . . unfortunately bench results on 'automatic' are a bit inconsistent, at least for some benchmarks.
