PowerMac G5 Dual 2.5 Vs iMac Core2Duo 2.16

Just want some help here really.
I would love to upgrade to a Mac Pro but it's not really realistic.
I have at the moment a PowerMac G5 Dual 2.5. I only use it really for Logic Pro 7 and Aperture.
I was looking at maybe getting an iMac 24inch one, to slim things down in my small home studio. Is it going to be faster than my G5, the same or slower or what??
Thanks in advance

I think it will depend on wether your favorite applications are universal or not.

Is the new iMac faster than my PowerMac G5 dual 2Ghz?

I have a PowerMac G5, Dual 2Ghz (first generation model)
2.5GB Ram, and a ATI 9800 Pro 256mb Graphics Card.
Looking at the SPEC ratings on the Apple page, the new iMac (2.0Ghz model) scored...
SPECint_rate2000 = 32.6
SPECfp_rate2000 = 27.1
And according to http://www.apple.com/lae/g5/ the dual 2Ghz scored...
SPECint_rate2000 = 15.7
SPECfp_rate2000 = 17.2
Doesn't this mean is roughly twice as fast? Does SPEC just measure the processor or the whole system?
And how does my ATI Radoen 9800 Pro 256MB compare to the ATI Radeon X1600 256MB?
Thanks!

I agree. Specs are great and certainly are helpful in comparing the new MacBook to the new iMac as they are quite similar. What's really interesting is how PowerPC coded apps will compare to their universal binary equivalents on the new machines. I for one am curious to see how the universal binary of FCP Studio runs on the new iMac vs today's PowerMac. While people have been using FCP tools on G5 iMacs and G4 PowerBooks, performance isn't nearly as good as the same app on a Dual or Quad G5 PowerMac. It could usher in a whole new segment of Pro tools users who can get good performance from a less expensive option like the new iMac.

Imac intel core duo or powermac G5 dual

I am just starting out in graphic design. I have not bought adobe/macromedia software but I do have plans to buy cs2 and upgrade to cs3 when it comes out. Other than that I have no equipment but would like to start out with learning on mac. I just need some suggestion, and yes I have search some of the older post. But like older post the information is old sometimes also. Which one should I get 20' imac intel 256 ram or referb powermac G5 dual. Thanks for your opinion and time.

I had the same situation a while back where i actually bought a G5 refurb but sent it back and swapped it for a intel imac, mainly because i needed a better graphics card for the G5 and at this point there are still no better cards available to buy.
Mine is the 17" and i have to say it runs the G5 pretty close, basic Photoshop action seem to run ok but there would be a hit with intensive tasks etc i would imagine. You have two issues here though, the current imacs have been out since Jan 06 so could well be due for an update of some kind soon and the same goes for the G5, roumers put a replacement for these at around July August so i would hang on a bit if you can.
If you can't it's possible (but by means certain) that a refurb imac 20" could have the 256mb card in, my G5 came with the 256mb card instead of the 128mb but that's only through luck!

Powermac G5 dual 2.5 issues!

I purchased a pre-owned Powermac G5 Dual 2.5 ghz. It has 4gb ram and is running Mac OSX 10.5.8. Very shortly after I purchased the computer I had a crash and couldn't get it to start back up. I tried to re-install software and it would go part of the way thru and crash on the install every time. I started the machine in target mode and hooked it to my old trusty G4. I was able to install the software that way with no issues. I then went back to the G5 and tried installing updates, but part of the way thru the updates it would crash saying the update was possibly corrupt, ( these were straight from apple so I doubt that ) thus leaving my g5 unable to restart because of the partial software update. I did the target mode again, this time installing all of the updates using my G4. After all was said and done, I was back to where i had started when i bought it. I now keep to be getting freeze issue with the machine. I can be online using safari and all of a sudden I get the spinning color wheel. When this happens I can not even force quit the app, it will just sit there spinning away. Tonight i tried opening firefox and it started up and ran for a few minutes before freezing also. A few days ago I had tried to burn a dvd using toast, and that app also froze up and would not let me force quit. I have not had any issues like this from my G4, and after trying resetting the SMU, PRAM and many many hard restarts, I am no closer to knowing what the issue could be. Any help or ideas for me to try would be much appreciated. Thanks, Mike

Have you blown the dust out of it since you got it?
Possibly a temperature problem or bad RAM/RAM slots.
Get Temperature Monitor to see if it's heat related...

If you have any temps in the 70°C/160°F range, that's likely it.

Remove the metal side panel. When you press the power button, do you see anything happen? Does the power light flash at all? Do you see a red light on the logic board?

PowerMac G5 Dual 2.5 - Only Boots with Side Cover and Fan Guard OFF!!

I have the strangest problem with my PowerMac G5 Dual 2.5. This has been my Pro Tools rig forEVER.
At some point early last year, my Mac wouldn't boot. It would not see the hard drive, and would show that dreaded alternating icon in the middle of the screen indicating as much. I tried resetting, tried power off/on, tried resetting PRAM. Nothing. I took the cover off, and fan guard off to get at the hard drive. Verified the data and power cable were seated in hard drive. Cover still off, I booted up the system. Voila!!! Booted right up like nothing was ever wrong. I put the cover back on, and went about my business, passing it off as a one-off power glitch (the power in my house ***** rocks). Next time I rebooted the Mac, the exact same thing happened.
I can repeat this at will. If I leave the cover on, the system will not ever, ever boot. The minute I take the cover and fan guard off, causing the fans to spin at max speed when turned on, the system boots without issue. So, I reset PRAM and PMU. I even tried replacing that green/white cylindrical battery on the motherboard. Reseated power/data cable on hard drive. ****, I even tried a different hard drive and memory (explained below). No change.
Since then, I have relegated this system to the emergency backup system, and procured Dual 2.7 G5 PowerMac. I transferred the pro tools cards, hard drive (without formatting it) and memory (8 GB) to this new 2.7, and have not had a single, solitary issue with it. So, I know it's not the hard drive, memory, OS install, or Pro Tools cards.
What in the name of the Apple Gods could be causing this issue? Any ideas at all?

Hi Chris,
Good info & work so far, but indeed strange, only thing I can think of is something to do with that little switch for the fan cover... near the bottom as I recall, but it may be some kind of short in it's circuit.

PowerMac G5 dual core resolution

I'm having problems reaching the native resolution on a 26" Dell W2607C LCD-TV.
Should the factory fitted nvidia 6600LE (PCI Express) be able to support 1366x768 pixels? I've read that the single-link DVI port supports up to 1920x1200.
PowerMac G5 Dual Core 2.0GHz Mac OS X (10.4.3)

been a bit foolish here...
installed switchresx, unable to make custom resolution 1366x768 active. Then realised monitor was connected to DVI-2 so moved it over to DVI-1 and restarted G5. Voila I have a host of new resolutions that fit the bill perfectly.
Just not sure whether it would of worked without switchresx!
Thanks for the advise.

Which is better for Pro Tools LE-PowerMac G5 Dual-Core 2.3Ghz or Dual 2.7Gh

I'm starting a small recording studio and I own a PowerMac G5 Dual-Core 2.3Ghz with 2GB of RAM and a PowerMac G5 Dual 2.7Ghz with 2GB of RAM. I need to keep one of them to run Pro Tools LE. Both G5's have the same hard drives and similar graphics cards..Does anyone know which would do a better job and if so why ??? Thanks..

Hi popped!
You have posted your inquiry, in the Discussions Forum, that is intended for discourse about the use of Apple Discussions.
You will get more attention to your issue, if you select a more appropriate location from this page Discussions Forum Home.
Perhaps posting in one of the Power Mac G4 & G5 Forums, would generate more interest.
Good Luck!

Is it manitory to have an airport antenna or can you use it without the antenna (powermac g5 dual processor 10.4.11)

Is it manitory to have an airport antenna or can you use it without the antenna (powermac g5 dual processor 10.4.11)

On the PowerMac G4 I had it had to be connected, but not sure about the model you have. My guess would be yes due to shielding in the case, but would rather wait and hear from someone else.

Thermal issues with PowerMac G5 Dual 2.0 Processor

I've been having issues with my fans running super loud for no apparent reason. I have been told that my thermal meter for one of my processors has gone bad and that I have to replace both my processors at a cost of over $800! I am simply wondering if there has been any other issues even similar to this one or if anyone can tell me if I really do have to have both processors replaced for this situation. Also, I am wondering if anyone knows how to run the processor diagnostic where I can view my computers feedback for myself.
I am a starving designer and desperate to fix my biggest tool. Please let me know of any possible suggestions or cheap fixxes. If there is no way around replacing both processors, please let me know of any good mac processor retailers! Thanx all!

You can check the temps and fans with

or
http://www.kezer.net/thermographx.html
Who has told you what the problem is? Has the G5 been in the shop?
Is there a pattern to the loud fan noise?
Is there a red light on inside?
How warm is the room?
Is there a dust build-up inside the G5?
A simple thing, but is Energy Saver - Processor Performance set to 'Automatic'?

Fans only run slow, not fast on PowerMac G5 Dual 2.3

I've noticed recently that some occasional kernal panics seem related to the fact that under a heavy load my processor fans are not revving up. This is on my olde PowerMac Dual 2.3 from some time ago. We have the same model at one of our workstations at work and the fans kick in and out as we render, so I know what a healthy PowerMac G5 Dual 2.3 should sound like.
I've checked inside the case... the two fans in front of the processors are running, just really slow. The same with the two rear fans. I can't get them to spin up faster when doing anything processor intensive. Seems like it's been like this for a while, though it was definitely not always like this as I recall a few mornings where I found it in jet engine mode.
The white tab on the clear plastic internal cover is seated correctly... I don't know where any other sensors might be.
I ran the Apple Hardware Test from my original gray install disc... upon booting into the test I was surprised to hear the fans revving up to full speed. On the first run the computer had no problems. After a reboot into the OS and then another reboot back into the test disc, the full speed fans just locked up the OS choice screen and I couldn't get past it.
I see plenty of posts here regarding loud, fast fans that won't spin down... but I don't find too many with this problem.
Can anyone shed any light on this?
Thanks,
Dave

I run BOINC on my Power G5 and it places a full load on the processors for as long as the application is up. I find the fans are not very loud if you have done a proper dust cleaning of the computer. This includes cleaning out the power supply that's located in the very bottom of the case. If you think you have a problem I suggest you look into Istat Pro from http://bjango.com/. This will allow you to look at the fan speed to determine if you have a problem or if things are running normal. Under full load, my fan data looks something like this.
Drive bay 1000 rpm
Backside 1100 rpm
CPU A intake Around 800 rpm
CPU B intake Same as CPU A
CPU A exhaust About 30 RPMs higer that CPU A intake
CPU B exhaust Same as CPU A exaust
Slots Intake 1560 RPM
The only fans that seem to change much based on load are the CPU fans and with no load they may drop to about 500 RPM. Under full load on a warm day and the system in need of having the dust clean out I have seen the fans go up to 950 RPM. The fans that made the most noise were the Power Supply fans when I missed blowing out the power supply for a while.
The G5 processor is able to run at temperatures up to the boiling point of water but it truth I have never seen mine get above 164 degrees fahrenheit.
If you have just done a good cleaning of the system, it's possible you have just returned the system to normal operation and extended it's life instead of having a problem.

PowerMac G4 Dual 1.25Ghz won't let me install updates to Leopard

Hi there.. I just bought a PowerMac G4 Dual 1.25Ghz and for some reason, I can't install Leopard through the DVD drive. I get an error saying something about <Base System> and when I did install it leopard by making the powermac a firewire drive, now I can't do any updates. I get a message that the file is corrupt and contact the software vendor. I tried doing a Repair Permission, but it wont do it and keeps going and going.... Has anyone had any issue like this?

First, did you install Leopard using a retail version installer. Using an installer from another Mac model won't work.
Second, is this the update file you tried to use? http://support.apple.com/downloads/MacOS_X_10_5_8_ComboUpdate
It's best to download the update file & install off line, rather than use the auto update feature. Repair permissions before & after installing the update.

Powermac G5 Dual 2.0 Ghz machines made in 2004 ship with Tiger or Panther?

Reason I'm asking is I bought this mac used. The dude forgot his password, the machine freezes up intermitently, so I think I should reload the OS. However he forgot to give me the OS X system disks that come with it. He's been avoiding my phone calls about this. So I'd love any help anyone can give me on this system freeze up and password issue. Thanks!
Here are the specs:
Machine Name: Power Mac G5
Machine Model: PowerMac7,3
CPU Type: PowerPC G5 (2.2)
Number Of CPUs: 2
CPU Speed: 2 GHz
L2 Cache (per CPU): 512 KB
Memory: 1.5 GB
Bus Speed: 1 GHz
Boot ROM Version: 5.1.8f7
150 gig HDD
Powermac G5 Dual 2.0 Ghz Mac OS X (10.4) 1.5 ram, 150 gig hdd

Other than having to buy Tiger OS, there is no reason not to. I have Tiger on even older 2003 G4 MDD and Blue G3 (Yosemite) still running 10.4.9. Well, I don't use the G3.... but I 'could' - and run okay for basic stuff.
The only things to consider is that you have updated your software and such to run on Tiger (can't see that being an issue 2 yrs after Tiger shipped, unlike Apr 2005 when it was a 'learning curve' for all of us).
I would backup, and then use Tiger DVD to re-format (Partition) and install, and then import or merge my files afterwards. Anyone with G5 from prior to Apr 2005 really is more likely and should upgrade to Tiger than stay with the original OS.

PowerMac G5 Dual 1.8GHz Booting Up Problem, HELP!

*I have an Apple PowerMac G5 Dual CPU 1.8 GHz.*
*This machine has a problem where it will not always boot up. Basically when the machine is cold, it will powerer up, but then give 3 flashes of the power LED, which signifies a memory error. If you leave the machine on, after warming up for 15~30 minutes, this machine will often be able to be reset and then will boot up normally and work fine. This doesn't work 100% of the time but it does sometimes.*

Hi Kompefx, and a warm welcome to the forums!
How Much RAM do you have, can you pull 2 stick & try it?
See if you can Boot off your Install Disk while holding down the *d key*, (not c key), then run the extended Apple Hardware Test. Some disks require you to use the Option key at bootup to select AHT. Some models have a separate AHT CD.

Powermac G5 Dual 1.8Ghz RAM question

I purchased one stick of 1Gb RAM and installed it on the motherboard, but I didnt know it had to be installed in pairs so the computer wont recognize it. I made an order for a second stick and it should arrive in a couple of days. Can I use my computer with the one stick still in there, or do I need to remove it and install both at the same time?
Powermac G5 Dual 1.8Ghz Mac OS X (10.4.9)

dfernandez86-
I am confused so this is probably a dumb question, but how can using 1 stick be configured as a pair?
I would take the new stick out and use it as originally configured. When you get the second stick have at it.
