IMAC REVIEW INTEL DUO CORE VS
By :hardware review

The first two versions of the Apple iMac G5 were wonders of design
and engineering, and the newest version continues on that same path.
The newest 20-inch iMac G5 ($1,699 direct) adds a few features,
including upgraded graphics and a slightly faster processor, while
cutting the price by $100. On the whole, the iMac G5 (iSight) is an
evolution of the design we first saw a year ago, and we consider it an
improvement. The iMac G5 is a great desktop for Mac users whose needs
go beyond simple Web browsing and e-mailing.
The iMac G5's appearance hasn't changed much from the previous
version: Sharp-eyed users will notice the now-curved back panel, which
makes the iMac seem more organic and less bricklike than the previous
version. The power button has been moved from the back right to the
back left, no doubt to prevent people from accidentally turning the
iMac off when plugging in a cable. Speaking of cables, the USB,
FireWire, and VGA/video adapter ports now run horizontally instead of
vertically. And with the multibutton Apple Mighty Mouse now standard, the people switching from Microsoft Windows will finally be able to right-click and scroll with an Apple mouse.
The integrated iSight cameraвЂ”the main focus of the new iMac
upgradeвЂ”provides iChat A/V video-conferencing capabilities as well as
the usual picture and video webcam duties. A neat novelty program
called Photo Booth lets the user select filters for self-portraits,
giving your iChat/AIM buddy pictures visual qualities such as sepia
toning, "X-ray" coloring, and other effects. In theory, this could turn
people into avid webcam users, though in practice, most adult users are
likely to take their picture once when they first get their iMac, then
forget it's there.
The Apple Remote with Front Row interface is another story. The
remote gives the iMac features very similar to those of a Media Center,
albeit without the TV tuner. Front Row is a simple yet powerful control
panel with the same sort of "10-foot interface" found in Windows Media
Center Edition. You can see song titles and the like from across the
room, from the comfort of your bed or couch. The included infrared
Remote looks like a shrunken, thinner iPod shuffle , with the same five-way control pads for volume, track forward/back, and play/pause, as well as a menu control button.
Using the remote and the Front Row software lets the user control
iPhoto (slide shows), iTunes (music), Videos (downloads and Video
podcasts), and DVD movies from the comfort of an easy chair. Once set
up, the combination works well, with the "no-look" interface you're
used to if you have an iPod. This is a big improvement on most MCE
remotes (or even consumer electronic remotes like the one for your
cable box), where you have to look at the remote constantly to see if
you're hitting the right button. The Apple Remote also works with the
new iPod Universal dock ($39), which has IR built in to control a
docked iPod, iPod mini, or iPod nano.
One issue we found is that if you don't have all the media software
(iTunes, QuickTime, and so on) set up yet on the iMac, Front Row will
come to a halt trying to figure out what to do. Even the End User Legal
Agreement (EULA) screen that appears when you start up iTunes for the
first time after installation or an upgrade will halt activity. Since
Front Row accesses the iTunes library through its interface with that
program, it freezes because it doesn't know what to do when iTunes
wants you to hit "Agree" on the EULA screen. Similarly, you can't view
movie trailers in Front Row until you set up QuickTime 7, including
entering the speed of your Internet connection. It would be nice for
future versions of Front Row to take care of this stuff through a setup
wizard, in case you're using your iMac for the first time. Once you
have iTunes and QuickTime set up, Front Row is a joy to use.
Apple didn't build TV-tuner capabilities into this iMac/Front Row
combo: The company left that to third-party manufacturers like
Hauppauge/Eskape and Elgato. This means you'll need another remote if
you want a TV tuner, which complicates things. TV and video weren't
really an issue until recently, when Apple introduced the 5G iPod with video capabilities Right now, iPods are limited to the video content from iTunes Music
Store, TV programs, and downloaded video podcasts. Any home movies you
put in the Movies folder on your iMac will be viewable using Front Row,
but there's no easy way to get those onto your iPod. Yes, you can
convert your QuickTime-based videos to an iPod-friendly format, but
there should be an easier way to get DVR-recorded or DVD-based video
content on your iPod via your iMac. We're sure the third-party
developers are working on solutions as you read this.
W e have tested Adobe Photoshop CS2's performance,
which was very good. The scoresвЂ”Gaussian Blur at 5 seconds, Unsharp
Mask at 3 seconds, Lighting Effects at 9 seconds, and Image Resize at
10 secondsвЂ”show that the iMac is powerful enough for light to medium
graphics duties. These tasks, particularly Image Resize, often take
more than a minute on older Macs with previous versions of Photoshop.
The iMac G5 is certainly powerful enough for day-to-day office and
graphics tasks, and it's a step above the Mac mini,
which is best used for basic tasks. Anyone who uses a quad-core
PowerMac at work should be happy with the iMac's performance at home.
Doom 3 performance is still fairly anemic, at 20 frames per second,
though this is an improvement over the previous iMac G5, a 2.0-GHz
machine that came with Radeon 9600 graphics and got a score of 14 fps
at the same 1,024-by-768 resolution. We're sure the improvement is due
to the upgraded graphics (X600 XT) and the new PCIe-based motherboard.
But Doom 3 performance still lags behind that of mainstream Windows PCs
with discrete graphics.
The iMac G5 with built-in iSight is a very good reworking of an
excellent product, with additions that enhance the all-in-one nature of
the iMac. It's a great mainstream Mac desktop for people whose
computing needs extend beyond simple Web browsing and e-mail.
Performance 2x faster
One giant leap for iMac
More than an evolution of
processor design, Intel Core Duo is an order-of-magnitude leap forward.
ItвЂ™s the first Intel chip born of the new 65-nanometer process, which
allows for the creation of transistors so small, you could fit a
hundred inside a single human cell. With two powerful processors
designed to share resources and circuitry so unimaginably small, Intel
Core Duo achieves far higher levels of performance while actually
consuming less power.
mac g5 review
All scores are in minutes:seconds. All systems were running Mac OS X
10.4.4 with 512MB of RAM, with G5вЂ™s processor performance set to
Highest in the Energy Saver preference pane. Using iMovie, we applied 3
different video effects to a 1-minute movie, one at at a time. Next, we
imported 100 JPEG photos into iPhoto and then exported them as a
QuickTime movie, as a Web page, and as files, resized to be not more
than 2,000-by-1,500 pixels. We created a Zip archive from a 1GB folder.
We converted 45 minutes of AAC audio files to MP3 using iTunesвЂ™ High
Quality setting. We saved an iDVD project containing a 6-minute,
46-second movie as a disk image. We used iSquint to compress the same
movie for iPod video playback. We used BBEdit to run a Text Factory
containing five editing, replacement, and sorting tasks on a 75.1 MB
Start up performance
Start performance with new gmac duo core show pretty signifiant improvement about 50% faster here.tis quite amazing performace boost
Imove 6 performance
again here the new powerfull intel cpu comforim te solid high performance of the new imac core duo about 70% better
Iphoto imac g5 benchmark
THe IPhoto performance is also pretty impressive except for the export file where the new imac is lower than the imac g5 with 15 second
Create zip archive imac g5 performance
Itune imac g5 benchmark
IDvd imac g5 performance
Isquint imac g5 benchmark
BBedit imac g5 benchmark
And here is the full chart
iMac has always made it fast and easy to do the most amazing things.
Now the fast and easy part literally doubles overnight вЂ” because the
newest iMac computers are powered by the Intel Core Duo. This
revolutionary bit of technology is actually two processors built into a
single chip, giving iMac up to twice the horsepower it had previously.
So the wows will come faster than ever before.
