Erm...huh? iLife 06 is native. QT is native. The tests are accurate, albeit they only take advantage of one core, like most consumer apps for the time being.

Weird how it's not there.

That's very good news.

I wouldn't be surprised to see the new iMac stay much cooler and produce less noise than the iMac G5. I think it's no exaggeration to say that at the same clock a Core Duo performs about as good as a 970FX - some would probably go so far as to compare it with the MP. If you recall Steve's performance per Watt diagram from MWSF, the Core Duo was something like 4-5 times higher than the G5. I guess that gives us an idea of how much less heat gets dissipated from the Core Duo. It's definitely a pretty impressive chip.

Looking at performance per watt sort of distorts the heat comparison since as we've seen the performance of Core Duo and the G5 at the same clockrate is not equal.
PPC970FX at 2.0Ghz uses 47W (power optimized parts) to 56W (standard parts), while Core Duo at 2.0Ghz is rated at 31W. In the scheme of the entire system that's only about 10% change.

[Simon]

10% less dissipated power is a great number if you keep in mind that performance has actually increased. People are getting more CPU power and at the same time need less cooling capacity -> less noise. IMHO that's a very good thing.

For obvious reasons, nobody was expecting 4-5x less heat just because the performance per Watt number was 4-5x higher.

[MORT A POTTY]

even a tad bit quieter would be a nice thing to have on the iMac G5. I'm using a Rev. A 1.8Ghz 20" and it's got a steady mid-range hum from the fans. blowing out hot air through the chimney in the top.

If the Core Duo can up the performance by about 100% and maintain even a similar and HOPEFULLY (but probably not realistically) a small reduction in noise, I'm going to love my new iMac

Please ask away if you have any questions or want me to test anything.

Hang on - did the iMac come with Comic Life pre-installed then? Cool if it did, awesome app!

I'd never heard of them before, but it's good to hear. I would be surprised if VMWare didn't have something shortly too... so I think we'll be okay with virtual Windows before long.

I know this is probably a stupid question... but I have to ask...

Are you saying that it tried to boot from the CD, but couldn't load.
Or that it simply ignored the CDs entirely?

Thanks

Thanks a lot Todd. Can you make a new key and encrypt / decrypt some files. It install contexual menu items to do that also. Second thing I use is the encyrpted disk image, similar to OSX's dmg images. I don't care about Mail.app integration or ichat integration. File operations and disk operations are ctirial for me.

Again thanks a lot, I am so happy so far.

I want to buy a Imac Intel, but the question is, i work with Dreamweaver and Flash MX or 8 is it compatibel with the Imac Intel??

I haven't seen a single benchmark from a REAL program that substantiates this. The ones previously linked to show about a 10% improvement in iLife score.
I thought iMovie, iDVD, et al were designed to use dual processors, but I guess not. If the Intel version isn't, then perhaps we'd see more improvement if the other core was used.

Render 10 Second Ken Burn's Effect
14 seconds, iMac G5 - 1.8 GHz 256 MB RAM
9 seconds, PowerMac G5 dual 2.0 GHz 512 MB RAM
13 seconds, iMac Intel Duo, 2.0 Ghz, 512 MB RAM (5 second delay/stuttor on the "import" of the photo)

Render Six 2 Second Cross Dissolve Simultaneously
31 seconds, iMac G5 - 1.8 GHz 256 MB RAM
20 seconds, PowerMac G5 dual 2.0 GHz 512 MB RAM
24 seconds, iMac Intel Duo, 2.0 Ghz, 512 MB RAM

Export 1 Minute of Video to QuickTime using for CD-ROM Setting (H264)
35 seconds, iMac G5 - 1.8 GHz 256 MB RAM
22 seconds, PowerMac G5 dual 2.0 Ghz 512 MB RAM
94 seconds, iMac Intel Duo, 2.0 Ghz, 512 MB RAM

Create Disc Image in iDVD using Travel Cards theme and 10 Minutes of Video
12 minutes, iMac G5 - 1.8 GHz 256 MB RAM
9 minutes, PowerMac G5 dual 2.0 GHz 512 MB RAM
10 minutes, iMac Intel Duo, 2.0 Ghz, 512 MB RAM

(I removed the other Macs so that we can see iMac to iMac Duo and iMac to 2GHz PowerMac specs.)

Note that the iMac G5 has only 256MB ram. The Duo iMac is not twice as fast. In fact, it's always slower than the Dual G5 2GHz.

I thought I saw some iTunes encoding benchmarks around the 'net, but I don't know where they are.

I had also read somewhere that the video card in the iMac Duo handles the H264 decoding for playback really well, but, again, no proof. We need somebody to start compiling all these comparisons.

I don't know about iDVD, but I remember the Macworld tests that showed a single CPU iMac G5 scoring the same as a dual Power Mac G5 in iMovie. So, no, iMovie is not multi-processor aware.

Look here. Fresh Ars review. In CD ripping through iTunes, the Intel iMac at 1.8 GHz is roughly the equivalent of the dual Power Mac G5 at 2.5 GHz.

So, I don't understand why people complain so much about the new machines. The hardware power is there, we just need the appropriately optimised software to unleash it.

It's there, I noticed it when I was doing get info's to see if anything was not a universal binary. I haven't run it yet.

I didn't get through all the apps and utilities, but everything in the root of the Applications folder is a universal binary. (Didn't look at apps in subfolders yet, including the utilities folder...while I was doing it, I thought of something else I wanted to try and never got back to it...so much fun to have, so little time!)

Well, I was going to post something about this, so I'll use a reply to your message to do it. This morning, I took six h.264-encoded movies (from the best of Tom Hanks on SNL) and ran them on my 20" iNtel iMac. Six was pretty much the limit. After that, things started to skip. I have a screen shot, but it's HUGE and I don't think I should post it like this. When I get home tonight, I'll scale it down and then post a link to it. I had the movie info window open and you can see that at least one of them is running at about 24 fps. I also showed activity monitor showing Quicktime using about 160% of the cpu. All six of these movies were encoded using HandBrake at 1000 kbps bit rate.

For comparison, a single mp4 movie jumps around between 30 and 60% of cpu while playing back.

Limewire on the intel macs doesn't work under Rosetta. It installs but will not launch.

I also found that iSync, which worked fine with my V600 on my old iMac, crashes before finishing the sync on the Intel Mac. I haven't had a chance to try any trouble shooting.

ISPQ works


Anyone try Roxio Popcorn or Mactheripper?

[starman]

Can someone with an Intel iMac do me a HUGE favor?

Go into the Terminal (Application->Utilities) and just type the command 'set' and post the line that says "MACTYPE="? I'm still using a beta OS with this developer machine and I desperately need to know what the final settings of "MACHTYPE" are. On my beta OS, it still says "powerpc-apple-darwin8.0".

Thanks.

Mike

I'm not speaking of the MacBook my friend

Go to the iMac specs page and it's not mentioned.
