POwerMac G5 Dual Core vs Dual Processor

Am thinking about upgrading my G4 computers and going to the G5 Powermac. More than likely a dual processor or dual core. What is the difference between the dual processor and dual core? Is there any difference between these re: efficiency and how they work overall?

A "dual processor" refers to two physically distinct and separate chips. A "dual-core" refers to 2 processors on a single chip, often sharing certain resources (eg cache, memory, etc).
As far as I know, the only dual processor G5 Apple currently offers, is the Quad, or 2 dual-cores. The 2 GHz & 2.3 GHz machines, have only a single chip with dual-cores (2 processors on each chip), to the best of my knowledge.
To the best of my knowledge, having separate chips is better whenever possible, than multiple-cores (processors) on a single chip, because multiple cores have to share resources.
However, if you can only have a single chip, multiple-cores (2 processors) are advantages. It won't double your productivity, but should give it least a 40-60% boost. This assumes that the specific software you are running, takes advantage of multiple cores. A lot of software does not take advantage of multiple cores, and having a multiple-core machine is a waste.

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.

I cannot install Leopard 10.5 onto my PowerMac G5 (dual processor)

I have a new retail full install DVD of Leopard 10.5 and cannot install it to my PowerMac G5 (dual processor). I bought a new disc, thinking it was the original. Nothing! I bought a new SATA 1tb hard drive... Nothing! I have reformatted until I can refomat no more. I have tried to "Safe Boot", holding down C, Option, Shift, etc... Can someone tell me what to do?

Hmmm, with the Leopard Install Disc in use Disk Utility to Verify the DVD, does that come out OK?
If so ...
1. Insert the Mac OS X Install disc, then restart the computer while holding the C key.
   2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu. (In Mac OS X 10.4 or later, you must select your language first.)
      *Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.*
   3. Click the Erase tab.
   4. Click the disclosure triangle to the left of the hard drive icon to display the names of your hard disk volumes and partitions.
   5. Select your Mac OS X volume.
   6. Highlight the drive, select Partition Tab, then Format type... MacOS Extended Journalled, select the Security Options button, choose Zero Out Data, Erase... after completion hopefully you'll be able to install.

Dual-core 2.3GHz G5 processor Vs. Dual-processor 2.3GHz G5

I have just purchaced a DUAL PROCESSOR 2.3GHz G5 is there a difference with this to a DUAL-CORE ?
Apple sent me this and told me it was the same thing .
sent me RAM that doesn't fit .
so I call and they say they differ . that i need different Ram
or the newer G5 for an added cost of $500.00
is there a difference or are they milking me?
I feel as they should just send me the new one .

Hi TGX;
There are some significant differences between the Dual Core and the Dual Processor 2.3 GHz Powermacs. There is the difference in memory and there is also the difference of PCI Express in the Dual Core as opposed to to PCIx for the expansion slots in the Dual Processor. In addition the Dual Core has the 1 MB of cache for each processor which improves performance.
Personally, if it was my machine, I would send it back and request that they send what I had ordered.

MBP Core 2 duo 2.33 vs. PowerMac G5 dual 2.0

Hey all. Trying to decide what type of computer to buy here. Upgrading from a G4 powerbook (12", 1.5 processor, 1.25GB ram, 100GB 7200rpm HD). I will be using the computer for audio recording (up to 4 simultaneous tracks as of now) with various external firewire audio interfaces.
I am aware of the firewire issues with the new 2.4 MBP's so those are out of the question. My choices are a 1 year old MBP 15" Core 2 Duo 2.33 model with about a year of apple care left or a PowerMacG5 dual 2.0 (early or june 2004 most likely) with either 2x20" monitors or one 23" monitor. All will have about 2 GB ram. Price aside which would you all go for. Which has the obvious power advantage, dual core or dual processors. Also the MBP will have 256mb video ram, the PowerMacG5 will have either 64 or 128mb. obviously the MBP has the upper hand there.
Now to add price into the equation. The PowerMac will cost me about $1400 for the setup with monitors. The MBP, about $1900. What would you all do?
Also, can anyone enlighten me on the differences between different "models" (or production eras) of the MBP. I know the video cards changed manufacturers and ram size throughout the range. Did anything else change substantially? Is one of the "models" exceptionally better than another. Thanks alot...

Hi rycla, and welcome to Apple Discussions.

(a) Can anybody please confirm this is ok to install? (Size dimensions seem correct 9.5mm (height) x 69.85 (width)
Yes, any 9.5mm high SATA will fit.
(b) Would there be any heating issues related to it?
The chances are better than even that it will run hotter than your previous drive. All other things being equal (rarely the case), a 7200 will use more power and create more heat.
(c) How about power.. would it chew up more battery?
See previous answer.
(The reason I've opted for 7200 over 5400 is purely for speed.. I regularly use Audio Production apps as well as Photoshop & FCP so figured the faster RPM would be advantageous?
Again, all other things being equal, a 7200 will certainly be faster.

PowerMac G5 2.0 dual processor video Card installation

I installed a Radeon7000 64M DDR AGP VGA/TVO/DVI-I card in my powerMac G5 2.0 dual processor. I starts up with both screens fine, but freezes immediatley on startup. I started up in Safe Mode and it was fine. I repaired my permissions then Zapped the pram and it will start up fine and even got to adjust dual displays before it froze. It will not start up and operate correctly. I know Mac has the drive in its operating system. I am just frustrated because all I wanted to do was used an extra VGA screen that I have and the installed card only had one DVI and an Apple screen conector that I cannot get an adapter to VGA for.

Hello, are you sure that card can support 2 monitors your size?
I don't think that card suports core video or maybe even quartz, both essential for 10.5.x, but disabled in Safe Mode.
BTW, not sure what adapter is...

What is causing a PowerMac G5/2.3GHz Dual Processor sudden abrupt shutdowns

Hi all
I am posting in hope that someone out there can help me solve this very puzzling problem.
The machine: A PowerMac dual processor G5/2.3GHz (early 2005). 1.5G RAM. 250G HD. SuperDrive. Radeon 9650.
The problem: When under some load, this machine will suddenly and abruptly shutdown as though someone pulled the power cord. There is no warning. Just a soft click, and it powers off. The machine can be manually restarted after the sudden shutdown with no problems.
This problem is very replicable. (eg go to a particular website, play an embedded video, and boom, the machine shutsdown. Each and every time.) It was replicated at an Apple Store and at two Apple Authorized Service Providers.
System.log said "PMU forced shutdown, cause = -122"
Before the sudden shutdown, the machine seemed to be operating normally. The fans did not noticeably speed up. Activity Monitor showed no more than 50% CPU activity for each CPU. Temperature on both CPU was around at 70C before the sudden shutdown. Temperature and activity on both CPU goes up and down in tendem.
If I use the Energy Saver system preference to change "Processor performance" to "Reduced", the problem goes away. (As measured by going to the same website and playing the same video. Even playing 5 videos simultaneously did not cause a sudden shutdown.)
What have I done #1: I have reformat the hard drive with a 7-pass security wipe, followed by a clean-install of Tiger which was then brought up-to-date using Software Update. I then installed Safari 4.0.3. No other software is on the machine except Tiger and Safari. (Later installed Hardware Monitor to get me a handle on the temperatures.) The problem persisted.
What have I done #2: I then installed a new PRAM battery and reset PMU using the switch on the motherboard. Resetting the PMU also resetted the PRAM. The problem persisted.
What have I done #3: I then took the machine to an Apple Store. They found that they can replicate the problem easily. But, after 3 days of running the Apple Service Diagnostic, the diagnostic software didn't find any problem. They also did a thermal re-calibration. That didn't help either. Without an error code from the diagnostic software, the only "solution" the Apple Genius offered was to start swapping CPU, power supply and mother board at my expense. And even then, he has no idea which component to start swapping first. (Two independent Apple Authorized Service Providers offered the same non-diagnosis and roughly the same "solution".)
Has anyone encountered such a problem before? What was the solution?
How about an educated guess as to what's wrong?
I want to, if possible, and if reasonable, repair this machine.
Thanks in advance.
Lara

This sounds almost exactly like the problem I have. My G5 is also an Early 05 2.3G. I tried every tip I found on the forums from UPS vs. wall socket to stock RAM vs. 3rd party to booting from external HDs, etc.. I currently have 10.5.8 on it and it's running using the "Reduced" processor setting in Energy Saver prefs.
I have also made a trip to The Apple Store where the AS folks ran their diagnostics but were usable to replicate my problem. I understand they "can't fix it if it ain't broke".
Aside from the "Reduced" setting work-around has ANYONE actually solved this problem definitively? Although I have no interest in spending $1000 to fix this, I can't imagine disposing of it on Ebay.
Assuming this is a hardware issue, this would mark the first insurmountable failure of any of the 10 or so Macs I have owned.
Anyone? Anyone?

Mac OS X Leopard on a PowerMac G5 1.8 GHz Dual Processor

I have a PowerMac G5 dual 1.8 GHz on which I installed Leopard as an upgrade once v.10.5.1 was released. After the installation, I noticed intermittent problems of applications freezing on launch, abruptly quitting, and having to be force-quit to close. Some applications, especially Word and Quicken, sometimes give strange messages, such as being unable to find templates or unable to save memorized transactions or copies of a file. When these issues occur, rebooting the G5 makes them go away for a while. About a month after the initial installation, I did an archive and install of Leopard, but the same issues continue. Have any other G5 owners experienced these issues? If so, how were they resolved?

Regardless of OS, my dual 1.8 gave me problems right out of the box - kernel panics, freezes, force restart messages upon waking, and creeping corruption. I have had to wipe and reinstall roughly every 6-9 months. I am also aware of 2 other identical machines with the same issues - one where I used to work (the same issues were ongoing before I was ever hired). The contracted Apple service rep mentioned another identical unit with the same problems.
I had it in for service when warranty was still in effect and three more times since, all with the same issues. Apple replaced the RAM, the motherboard, then the processors, then the power supply - and still the problem persists. They had forgotten to reserialize the replacement motherboard, and I discovered that this was a used and recertified part. As far as I am concerned, they simply replaced one funky motherboard with another.
Interesting note - the last service guy told me that he was aware of "around 100 dual 1.8s with similar problems.
Apple should have replaced the entire machine, but they refused to do so, even with the issue being reported while under warranty and despite four service visits. I've owned 15 Macs so far. This is the only dog, but it is mangy as **** and always has been.

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!

Dual core 2.3 or dual processor 2.5 for FCP Studio 5?

I'm on the fence whether to buy a dual core 2.3 with a 7800GT card or a refurbished dual processor 2.5 with a x800 card. The saleman today was pushing the 2.5 b/c he said it was faster, though he said the x800 would run around 20% slower than the 7800GT. I had actually read that if anything the dual core 2.3 was faster. I've been looking all around (including barefeats.com) but can't seem to find much to confirm the graphics card statement. Thought I had read in a post here that they were also about the same speed. Is he right about this?
Untimately, I'm looking for something to run FCP 5 Studio and things like Boris Red and Combustion with. With the price difference being about $380 b/t the two options, which one would be faster and the better bet?
Thanks ahead of time for any help!

FCP doesn't care about your card. Much. Not now anyway, we have no idea what will happen in the next rev but the trend is toward offloading much of the work to the OS and GPU.
Buy what you can afford and buy what you think you need to make money now. You can always upgrade in 18 months when the second generation of the Intel machines are likely to be shipping.
Are you using Motion or Aperture? Different criteria. Dunno 'bout no Combustion, never been using it.

Solaris on Intel Dual Core Solo 2GHz Processor

Hi
Does anyone know if Solaris 10 X86 supports Intel Dual Core (solo) 2GHz processors?
Thanks

Don't know, and a quick cursory scan of the HCL didn't pop up anything in my face, but you can find out for yourself, and get some Sun swag, by going to http://www.sun.com/software/solaris/contest/hcl.jsp and downloading the app that will tell you if it will run or not.
You can also help out the community by returning your results to Sun for reference by other people.
All this is, of course, assuming you have the machine already...

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

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'?

How can you tell? dual core or dual processor

I recently purchased a G-5.... SUPER!!!!
How do I know if my new machine comes with a dual core processor
or is it a dual processor?

The easiest way is to go to the Apple support site and put in your serial number where it says "About your Apple Product". If it states Power Mac G5 (Late 2005), then it is a dual core model.
