Some notes:

iMovie results may be disk limited.

Cinebench 2003 is not G5 aware/optimized.

Finally, "real world" numbers...

Gotta say, that iTunes conversion stat is impressive, at around 45times realtime for mp3s and aac conversion. I think the iDVD clip conversion times were in minutes:seconds:frames; 40 seconds to convert those is pretty impressive as well (though they might be too small for a big difference to become apparent). Put it to work squeezing two hours of DV (at approx. 26 gigs) down to a 3.5 gig mpeg2 file, and then we've got a benchmark!

[edit]Looks like xlr8yourmac.com is getting hammered; I managed to load the page in question once, and now I can't get back to it. Slashdot effect?

****************************************************

I work at a university, and our dual 2Ghz G5 just arrived. I just did a quick iTunes benchmark, converting "Moment's Notice" (Coltrane) from AIFF, on the hard drive:

I just watched for the highest reached conversion speed factor:

Dual 2Ghz G5:
converting to 160 MP3: 45.6x
converting to 160 AAC: 33.5x

My 12" PowerBook G4 867Mhz:
converting to 160 MP3: 11.5x
converting to 160 AAC: 8.8x

The G5 is standard factory configuration.
The PowerBook is running Panther 7B53.

Both systems had nothing but iTunes running, and were not playing the tracks while converting them.

The iMovie export test was 40 seconds, which was actually comparable to a Dual 1.42GHz G4 - which is why I said it may be disk-limited, rather than processor limited.

The site is REALLY slow. I only got 1 picture to load. I want to see the benchmarks, which (at least the iTunes one) seems impressive.

yes, the xlr8 site is slow - but the dual 2ghz g5 is fast

quite impressive. would like to know the speedfactor to my dual 450 g4 :)

Its pretty dumb that he is testing with Panther on his Powerbook. Having been using Panther, i can tell you its a lot faster over all.

So if you are impressed with the gap in encoding time, consider it even bigger.

mp3 encoding

My 12" PB can encode mp3's at 10-11x at 192. Thought that was great after encoding almost 700 cd's at 2x with a CRT imac. Now I really wish I had waited to do that work.

I got to touch a dual 2ghz G5 today at my local campus computer store... That thing is beautiful... It's big, but beautiful...

Personally, I really don't trust xBench anymore. Some of the results show the 1.8 GHz G5 is slower than the 1.6 G5. Not very accurate IMO.

I'd still like to see a nice high number, but if it is not, so what. 45x ripping speeds is good enough.

I'm so excited and I just can't hide it

the delivery status of my dual G5 order is beeing assembled, delivery sept 7th. Hope it stays like this.

can't load the xlr8 site either.

those iTunes specs are very impressive.

we'll have to buy the fastest cd-rom available to benefit the cpu's speed.

or let the G5 render some 3D stuff while ripping cd's and play some games while rendering and ripping. :D

Boy, looks like "shipping to education institutions first" really meant "shipping to college people first." I'm a huge K-12 customer, placed a bunch of Dual G5 orders right after the keynote, and man - got bumped from 9/2 to 9/23 like most people. Very lame. Well, at least they're starting to ship - I would have reallly like to have at least one for the first day of school (which was today). Blah!

That blows.

EDIT: I could have sworn that xlr8 had mention that it was an institutional machine yesterday. Oh well, maybe it is his personal machine, in which case it don't make no sense. I still think it belongs to the college.

I just came from the computer store at the University of California San Francisco and they have 8 dualies and already last week they had about twice as many 1.6/1.8 units. They have a 1.8 on display, but there is not much on it for me to test it out with. Looks nice.

I'm quite impressed with the benchmarks. I do understand that some of them don't stress the processor as much as other components. I am very much looking forward to getting a G5 of my own, perhaps by the end of this year.

I wish my school would hurry up and just order one. They said it would be a few months before they replaced their old G4 (not even MDD) with a G5.

Ah, when will someone post a nice hi resolution picture of the innards of the G5?

It looks like the PCI-X tunnel is mounted on the other side of the motherboard? But I can't really check because the image has been shrunk down.

Wow. The two Apple Stores in my area don't even have Dual 2.0 GHz machines. I was at the Cherry Creek store last playing around with the 1.8 though. The manager even unlocked the box and let me look at the insides. I'm still wiping up the drool.

*sigh* I might need to borrow some money.
