2.7ghz Dual Core verses Single Core

Hi, I have a Pro Tools system with PCI audio cards that I sunk quite a bit of money into. Needless to say, I'm stuck in PowerMac purgatory until I come up with the cash to make a total PCIe conversion. With that being said, I am now trying to determine what the absolute fastest (dare I say the best) PowerMac was before Apple moved on to greener pastures. What I've been able to find with some light research is that they built the obvious 2.7ghz Dual Core machine but also momentarily built a 2.7ghz Single Core machine for some reason. Can anyone shed some light on the advantages/disadvantages between the two? Thanks!

You have received misinformation. The dual processor (not dual-core) model was the only one offered. Only the 1.6 GHz and 1.8 GHz machines were ever offered with a single-processor.
All G5s at 2.5 GHz and above were also liquid cooled, so you may want to take that into account. Should one of them develop a leak, the repair bill is astronomical, assuming you can't coax Apple into fixing it as a design defect.

Dual-Core or Single Core?

I wanted a new phone for my birthday. At first I wanted the Sony Xperia Play, but it didnt come out in time. I also see the reviews for the phone, and they dont look so good. So, I am now thinking about either the HTC Thunderbolt, or the HTC Incredible 2. But I realized that they both are single cores, not dual cores. Should I be caring for the amount of cores? I have an iPod Touch 3G, and I like the speed of that device. I'm not sure if it has dual core or single core, but i am fine with that speed. I also want an HTC because of HTC Sense. I like its UI better than Motorolas or Samsungs. And I dont feel like rooting the phone either (yet). So, should I be caring about the Dual Core or is a Single core fine?

If you're a tech nerd: wait for a dualcore, or you'll have CPU envy. If you're not a tech nerd, it honestly doesn't matter, get whichever phone has the features that matter to you (in this case, HTC Sense).
The Xperia Play makes me sad though... both because it's not out yet and because it's (so far) VzW-exclusive in the US V_V

Processor question - Dual core vs. single core.

I currently have an Aspire 6930 laptop that I bought about a year ago on clearance from Best Buy. I'm quite happy with it. It has an Intel Core 2 Duo processor (2.0 GHZ, 800MHz, FSB, 2 MB L2 cache), 3 GB DDR2, 320 GB HDD if that means anything. I'm not a computer geek so really don't know much about this stuff.
Our old laptop is a modular laptop (about 4 years old) which my husband is using (I won't let him mess with my Aspire - long story) and it's pretty much falling apart. None of the USB ports work, the CD/DVD RW is broken, one of the hinges is busted so it won't close properly and it runs slower than a snails pace as he's dowloaded any and all "speed up your PC" and "diagnose your PC" programs from the web - if it's on the web it must be true, right???? Anyway, I've taken pity on him and have decided to try to buy him a new laptop as a combination 10 year anniversary/42nd birthday/Christmas present. Money is a HUGE issue as I'm a SAHM and have been pinching pennies and clipping coupons from the grocery money to try to come up with some funds for this surprise. I'd like to stay around $400.
I've found this one at Best Buy and it has good reviews.... http://www.bestbuy.com/site/Acer+-+Aspire+Laptop+with+AMD+Athlon%26%23153%3B+Single-Core+Processor/9...
But it says it has a single core processor. What exactly is the difference with single core vs. duo core???
We are not gamers. DH basically uses the computer to surf the web, watch Youtube video's, upload and download photo's, burn DVD's, etc. He does talk with family overseas so I would need/like to add a webcam.
I was also looking at this Asus model... http://www.bestbuy.com/site/Asus+-+Laptop+with+Intel%26%23174%3B+Pentium%26%23174%3B+Processor+-+Mid...
But the Asus has a Pentium processor which I've heard isn't the best???? Also, it's over $150 more. Is the duo processor and increase processor speed (1.6GHz vs 2.1 GHz) really going to increase the speed/response time significantly for what we do on the computer?? An extra $150 is going to be really tough for me to come up with but if it will truly make a significant difference I will try to find it somewhere.
Your thoughts/recommendations would be appreciated.

Thanks for the input. We really don't have the space for a desktop which is why the laptop worked so well for us. The only place to put a desktop is on the kitchen table and then we are always taking it apart when family come for dinner (which is often). I thought of netbook, but it does seem so limited. My husband is an amateur photographer and I would like the larger screen so that if he decides to persue this he would be able to do some basic photo editing, etc.
I think I will go with the dual core processer. BB has an HP that is $429
http://www.bestbuy.com/site/HP+-+Laptop+with+Intel%26%23174%3B+Pentium%26%23174%3B+Processor+-+Black...
and then another HP that is $499
http://www.bestbuy.com/site/HP+-+Laptop+with+Intel%26%23174%3B+Pentium%26%23174%3B+Processor+-+Piano...
and I can't seem to find the difference?????? Except the cheaper on has more RAM??? Doesn't seem to make sense.
Thoughts on the HP???

Changing from Dual Core to Single core

If you ever need to change from dual to single core you just have to call Apple Technical Support to learn how to do it. Some third party software vendors software dos not support multi-threading. So it sometimes causes a kernel panic which unexpectedly quits the program.

ComputerGenius,
the easiest way: download and install the developer tools. These contain a preference pain called "Processors". With that one you can deactivate processors/cores individually.

2.7GHz Dual-Core Intel Core i7 vs 2.0GHz quad-core Intel Core i7

I can't decide which Mac Mini should buy, Mini with 2.7GHz Dual-Core Intel Core i7 or the server version 2.0GHz quad-core Intel Core i7, of course I'll upgrade it with 8 GB memory and SSD drive.
So what are you guys thinking of 2.7GHz Dual-Core Intel Core i7 or 2.0GHz quad-core Intel Core i7?
cheers

my dilemma is if i go 2.7ghz i5 with 8gb of ram and the 750gb (7200rpd), after i buy the magic mouse and the keyboard, i'm already into $1367.00....
where as if i got a imac for $1399.00 i'm looking at a 2.5ghz i5 quad core with 8gb ram and a 500gb hard drive, with the amd graphic chip. plus i'm also getting a 21.5" led screen. where as with the mini i would have to hook it up to my existing monitor or even share it with my existing computer.
i love the look of the mini, but it is really hard for me to justify spending that much money having to buy all the "extra's", just have a working computer. when i can just pony up $32.00 more and get a whole sytem...
please help me to justify buying a mac mini.

What the heck is Single Core, Dual Core, and Quad Core Processor Configurat

I am listing an eMac computer on ebay. I have all the information necessary except processor configuration. Do eMacs come with Single, Dual, or Quad processor configurations? Or does it vary? I don't even know what those are really.

Make sure to follow these steps when selling*:
http://www.macmaps.com/selling.html
As was already indicated all eMacs were single core.
Apple didn't start releasing multicore machines until the later G5s.

I'm looking to buy a macbook pro. I will be doing some video editing with it. Would it be better to go a bit pricier to get the 2.0ghz quad core or stick with the lower priced 2.7ghz dual core?

Video is the magic word for fast CPUs, large screens, maximum RAM and large HHDs. Ditto what eww says and do not order RAM and HDD upgrades through Apple. It is much, much less expensive through third party vendors.
Ciao.
I do some video work myself so I have an understanding of your needs.

Is it possible to run 2 2.7GHz Dual-Core Intel Core i7 8GB 1333MHz DDR3 SDRAM - 2x4GB 750GB Serial ATA Drive @ 7200 rpm together to get a better system

I want run 2 2.7GHz Dual-Core Intel Core i7
8GB 1333MHz DDR3 SDRAM - 2x4GB
750GB Serial ATA Drive @ 7200 rpm
Would it be worth while or better to get a full spec i7 quad core server

Just go for the > Mac Pro - Apple Store (U.S.) instead.

How much faster is the 2.7GHz Quad Core Intel Core i5 than the 2.7GHz Dual Core Intel Core i5?

Hi there,
I'm considering buying either a Mac Mini (2.7GHz Dual Core Intel Core i5) or an iMac (2.7GHz Quad Core Intel Core i5). I'm just wondering what the difference in speed is between the two different chips. If both had 4GB of memory would the iMac be a lot faster than the Mac Mini? I'm a graphic designer so I'd be mostly using Adobe Illustrator and Photoshop.
Many thanks,
Richard

@Allan: Let me put it this way. My main confusion points:
1) The 1st one is 2011 model dual-core i7 and the 2nd one is 2012 model dual-core i5.
2) The 1st one had AMD Radeon HD 6630 graphics and the 2nd one has Intel HD 4000.
3) As I am getting used, I am getting the i7 one with 8GB 1333Mhz RAM and the 2nd one with 4GB 1600Mhz RAM.
4) 1st one has USB 2.0 but 2nd one has USB 3.0.
5) 1st one was originally Lion but upgraded to Mountain Lion. 2nd one comes pre-installed with Mountain Lion.
The i5 one I am getting for around $115 cheaper. Kindly suggest which one I should go for. Thanks!

Can MacBook Air (1.7GHz Dual-Core Intel Core i7, 8GB RAM) be used to start developing iPhone apps?

I want to begin developing some simple iPhone apps. I have a MacBook Air (1.7GHz Dual-Core Intel Core i7, 8GB RAM). is this sufficient hardware?

Disco Plus Single Core v Dual Core

Discoverer Plus on a Quad/Dual Core processor machine has severe performance issues.
We've tested it against a machine with less RAM but single porcessor and is so quicker on the single core...
Any ideas?

Hi
On a client machine, there are known issues with hyper-threading which is using machines that have multiple cores. If you are using Discoverer 10.1.2 these issues have been fixed. I would advise you to patch up your Discoverer server to 10.1.2.2 using cumulative patch 6.
I have placed a posting concerning patches on my blog which you may find useful:

Power Mac MDD G4 1.25 Single Core vs. Dual Core

I am purchasing a 1.25 MDD G4 that has the single core processor. I am going to be using it for music recording and creation.
Am I going to wish I had the dual core? Or will I not notice the difference? I was previously using a 700mhz imac with 765mb of ram and overloaded it pretty quickly.
This machine, with 1 (which is has) or 2 (which I might install) gigs of ram should outshine that pretty significantly even with a single core shouldn't it?

Dual if you can, especially if you're looking to go to Leopard during the life of the machine. Single G4 CPU and Leopard is painfully slow, even at 1.67GHz.
Even the current entry level iMac blows away most of the G5's, except maybe the quad cores) so G5's should be reasonably priced.

Single Core vs. Dual Core - Temperature Differences

Does anyone else notice that CPU temperature is affected by turning off one of the cores using the apple CHUD tools? For me, the extensions report that it's running 15-20C hotter when I'm running single core. The case temperature seems to confirm this fact as well. Can someone with CHUD installed please try to duplicate this?
I've got a stock 15.4" MBP 1.83GHz/512MB - W8613.
Macbook Pro Mac OS X (10.4.6)

it also uses the battery more. I conjecture that disabling a processor also disables power management. This solves the hiss because the hiss is due to power management, but at the cost of more heat and battery usage.
I suggest using quietmbp rather than disabling a core.

Unable to capture data from Serial port using LVRT2010 in single core pentium 4 machine

I am using application written in Labview using windows Labview
Runtime environment 2010. Application creates a tunnel to intercept data from
Serial port.
My problem is, Currently, I am using single core Pentium
processor. When I am trying to intercept the data between COM1 and COM7 (COM 7
is a virtual port) it is not able to capture data.
When I am running Labview RT environment using dual core
processor machine it is running normally. I wonder whether it could be the compatibility issues with
single core Pentium processor.

Hi Magnetica
Are both of the machines running the same runtime engine,
drivers ect?
Have you had RT applications running on this
machine before?
Is the development computer a 64bit machine?
The processor is a supported model (See link below).
