First Owner Reports on PowerMac Dual G5 2GHz
Posted: Sept. 4th, 2003
Last Updated: Sept. 15th, 2003

Note: For PowerMac G5 related Tech Docs/PCI Card Compatibility, G5 specific Software Updates, etc. - see the this page organized by categories. I've also posted a page with Dual G5 2GHz tests (w/ATI 9800 Pro retail vs 9600 cards vs MDD Dual G4 1.25GHz in games and apps.)

The Sept. 3rd news page had the first reader report of an end user actually receiving a Dual G5 system. I don't understand how an early July EDU order would ship before a day 1 order (several student readers said their day 1 order was delayed) but here's the first reader mail on a Dual 2GHz G5 actually arriving to an end user (i.e. not a College/institution):

" Got my 2GHz DP G5 this morning. It was ordered on 7/3 through the edu channel.
It looks pretty funny sitting next to the old 'Gateway 2000' monitor connected to it; a temporary situation...
Eric M. "

I asked Eric if he could send a photo of the internals/run some real-world tests. (All the dual G5 results I've seen were from pre-production systems - not an actual shipped model.) I know many are going to think this is report is a hoax after having their day 1 orders (even EDU/student orders) delayed. Here's some of the photos he sent. (Quotes over the images are his.)

"An overview of the internals....Good lookin' organs"

"The RAM slots....Those lonely modules certainly need some company"

"The PCI compartment"

"A look at the heat sinks. There is certainly a large surface area to volume ratio here.
Looks more like an industrial heat exchanger than a CPU heat sink."

"I found this a little odd. There are four screws attached to the drive bay
fan enclosure that do nothing as far as I can tell."

(I suspect they may be spare screws for use when you add a 2nd hard drive perhaps,
although they look a bit large for that. (Turns out the screw heads are guides for the drive in the grooves.)-Mike
)

Note: The 4 large screws are for a 2nd hard drive. They screw directly into the drive and are used as guides/supports in the drive bay channels. (See the G5 Tech Docs/Info page here for links to Apple's G5 CIP page which has guides to installing drives, cards, and more.)

He also sent some initial test results. I later wrote to ask if he had run Software Updates (in case there were any updates specific to the G5 since the build). He had commented that "Other than the developer tools and X11, it's a clean OS".
Here's his system details from an ASP report:

    (Standard Dual G5 config.)
  • 512MB RAM (two 256MB dimms)
  • Pioneer DVR-106D firmware A606
    (Note - several single G5s have been reported as having an OEM Sony DW-U10A drive. Both normally support DVD+R/+RW also, but may not with Apple OEM firmware.)
  • OS X 10.2.7 (build 6S80)
  • 160GB Hard Drive (Seagate ST3160023AS)
    (Seagate specs show 7200RPM/8MB cache, 8.5MS avg seek)
  • ATI 9600 Pro/64MB (ID: RV350, ROM: 113-A13601-120)

I guess 10.2.7 adds native support for the DVR-106 drive (Panther betas were already reported as supporting it.) I asked if he could try a DVD+R or DVD+RW disc to see if the OEM Apple drive supported that media (the retail DVR-106/A06 does)

" I tested a Verbatim DVD+RW disk with no luck from the Finder or Disk Copy. The OS recognized it as a blank DVD and asked what to do with it. It 'mounted' in the Finder and allowed things to be 'copied' to it. But would not burn. Attached is the error message (and is about as vague as a Windows error message).

    "Sorry, the operation could not be completed because an unexpected error occurred:
    (Error Code -2147352509).
    "

I have Toast 5 but have not tried it. I'm assuming it will work. I'll let you know.
Eric "

iMovie DV->QT (CDROM size) Export Tests:

"Using the five iDVD clips (which I imported into iMovie) instead of the six iMovie clips took 88 seconds. The total video length was 1:36:17.
(he later wrote)
Got the (iMovie tutorial) files off an eMac.
It took 40 seconds (exactly) to export the six clips.
Eric"

iMovie to date does not seem to take advantage of dual CPUs as shown in past CPU Upgrade reviews comparison tests here, but I was curious as to how the G5 would compare. For reference a 1.467GHz G4 upgrade in my Digital Audio system took 41.6 seconds for the iMovie tutorial export.

iTunes AIFF->MP3/AIFF->AAC Conversion from Hard Drive: These tests are from another reader that had access to a Univ. Dual G5 2GHz system. (Thanks Nick!)

"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.
Nick M."

I asked Nick if he had access to a dual G4 system to run the same tests for comparison. (BTW - to the 6th grader that asked why Nick mentioned the song name - that's in case anyone else wanted to duplicate his test with the exact same song. (Different songs can be a different filesize/length etc. and of course different file sizes will result in different results/times to convert.)

He later sent more test results:

" I ran one of the tutorials for the molecular dynamics code GROMACS on the G5 and my old G4 500DP (Mac OS X 10.2.6).

I compiled the code using gcc on both machines (I haven't got it to compile with xlc). I used the default flags as determined by configure.

PC Mag compares Dual G5 vs Dual G4 vs Dual 3GHz Xeon PC (Sept. 19th, 2003) PC Magazine has a review of the Dual G5 2GHz that compares performance to a Dell Pecision 650 workstation with Dual 3GHz Xeon CPUs and a Dual 1.42GHz G4. You'll want to read all the pages (page 2 has apps test notes not on the results page) but the table of test results is on page 3. (The Avid Xpress Pro tests mentioned on page 2 are not listed on the results page however, at least not as of Sept. 20th.) Although they didn't mention it, hopefully they had the G5 Energy Saver set to "Highest" performance (see the power management/bus slewing note on the G5 Tech Docs page here about how this can affect cpu/bus speeds. Although it may have been running full speed in "Auto" mode during the tests, it's still preferred for performance tests to set it to highest performance.

PSBench7 (Photoshop7) G5 Results/Comparisons: (from the Sept. 17th, 2003 news page) (from a reader mail, I've used PSbench in past reviews/tests but not yet run it personally on a G5)

"Hi Mike,
Over on the Ars forums Ps7Bench results for a dual G5 have been posted. They are better than I thought they would be. Out front by a *very* nice margin. Some of the PS pros say that some of the tests in this bench are hardly ever used (e.g. watercolor filter). Hopefully a new PS bench will appear.

MW G5 Comparison Tests: (from the Sept. 12th, 2003 news page) Macworld as a page with some tests of each of the G5 models. Macaddict also posted their initial benchmarks of a Dual G5 2GHz later that day, limited initially to just a QT/DV to MPEG4 tests (similar to my upgrade review tests) and some Photoshop 7 filter tests. (I'm hoping they retest the other machines with 2GB of RAM in them as well as note how much memory was allocated to Photoshop.)
