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???

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.

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.

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.

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).

Extract report only runs on a single core

I am running the following extract report on a dual quad-core processor server with 32 GB ram and when I suppress empty rows the process runs on a single core which of course runs at 100% slowing down the process, but if I do not sppress rows all cores are used. Has anyone else experienced this or can i modify my report to improve performace?

One item unrelated to the DimBot issue:
If you have a time period that can be used to restrict on (for suppression), you can use the restrict approach rather than the sup missing, ala:
<RESTRICT (@DataCol(11) <> #Missing )
I'm not sure I would attempt this if you had to deal with multiple restrict's though -- I'm also not entirely convinced the savings would be substantial, but it could be based on the multiple core aspects.

Adobe Media Encoder only using single core of CPU (core parking has already been disabled and did not solve the problem)

I only edit videos every few months and the last time I edited a video was around 6-9 months ago. At that time, I noticed AME was only using a single core of the CPU and contacted Adobe who instructed me to disable core parking, which worked. After disabling core parking AME used 100% of all 12 logical cores to process the video and all was good. Then last week, I decided to edit another video and noticed AME was very slow and checked and it was again only using a single core to process the video, but core parking is still turned off. By slow I mean that a 10 minute video with the lens distortion correction preset and one video transition effect is estimated to take nearly 3 hours to complete. For comparison, the GoPro software processed the same clip with the same effects in 20 minutes. Also, through troubleshooting with Adobe over the last few days, I have also tried downloading previous versions of the software but the prior versions have the same issue.
The video I'm trying to edit was shot on a GoPro Hero 4 Black with 1080p Wide at 60 frames per second. The default video format for GoPro is .mp4. The output settings I'm using when I export from Premiere Pro to AME are H.264 with the YouTube 1080p HD.
My system:
ASUSSabertooth X79
Intel core i7 4930k (6 physical cores, 12 logical cores)
16GB DDR3 Quad channel RAM
Samsung 830 SSD 128GB
NVIDIA GeForce GTX 460 (not CUDA compatible, I know)
Please ask if you need any additional information to help solve this problem.

This has been driving me CRAZY... so going over the message boards from 2 to 5 am this morning I found the best explanation I have seen. The problem is that Adobe Creative Cloud is NOT "Processor Group Aware". Windows parses any more than 36 cores into "Processor Groups" and while the Pro version of Windows 7 & 8 can handle 256 threads they have to spread them across multiple processor groups.
Simple Version: AREA | How many cores does 3ds Max support?

Clearly, this is an Adobe Problem... If any engineers are reading this PLEASE review the below and incorporate it into your next build of Creative Cloud!!!

Macbook pro, dual core or quad core?

Hey guys Im getting an early college present and was wondering which Macbook I should look at. This will be my one and only computer while im in college. No photo editing or anything like that, maybe some video editing but it will be almost none. Will be used to surf the web and write documents. My question is should i get the dual core or quad core processor? Will it really matter for what i want it for? One thing I absolutely hate is lag! So the faster of the two the better.

tony477g wrote:
So if I went with the quadcore because you guys say it is faster than the 2.9 ghz dualcore. Would the difference be noticable between the 2.6 ghz and the 2.3 ghz? I noticed the 2.6 has 8 gb to the 4gb and 750gb to the 500 gb.
Well, actually, only one guy said the quad core would be faster, but it is not clear why they said that. You said you were only going to use it "to surf the web and write documents." Well, guess what. You don't need a quad-core for that. You don't need a dual-core for that. I've surfed the web and written documents on my old single-core iPhone. Those tasks are just not that demanding.
So unless there are more things you want to do that you haven't mentioned, there is just about no way it's worth paying for quad-core or a 2.6GHz processor if all you are going to do is surf the web and write documents.
The quad-core is going to speed up operations that specifically benefit from parallel processing, like intensive editing of photo/audio/video, or bulk encoding of audio and video, or specific math apps, stuff like that. And most Mac users would not benefit from choosing the 2.6GHz over the 2.3GHz because the performance of so many common uses depends not only on the CPU speed, but actually on the overall balance of CPU, RAM, and disc. In other words, if you really have a legitimate application for 2.6GHz it usually means you must also install a great deal more RAM and also an SSD to avoid creating a bottleneck that holds back the CPU. But then you would have a machine that is massively overpowered and overpriced for surfing the web and writing documents.
You could surf the web and write documents quite effectively on the least expensive MacBook that Apple sells. But since you do want to keep it throughout all of college, it is a good idea to buy something higher than the bottom of the line. For a Mac for very basic uses that should last four years, I would suggest:
13-inch MacBook Air with 256GB SSD storage and 8GB RAM
13-inch MacBook Pro with 500GB HD storage and 8GB RAM
13-inch MacBook Pro with Retina Display with 256GB SSD storage and 8GB RAM
(You didn't mention what your budget is)
I suggested 13-inch because it's more portable than the 15-inch but more comfortable for 4 years than an 11-inch. I chose storage sizes that would be appropriate since you said you would do some video. And I chose 8GB RAM because 4GB may not be enough for 4 years, and also because insufficient RAM is often a bigger cause of lag than CPU or disk speed.
If you have a limited amount of money, from this point on you'll need to justify why you would want a bigger screen, a faster CPU, or more cores given the two tasks you said you'd be doing most of the time. Because again, if you didn't actually need a Mac, you could write documents and surf the web on an iPad with the Logitech Ultrathin Keyboard Cover and be done for $600.

Set Duo core to single?

I require the ability to run with a single core due to a certain conflict with Duo Core running and need some help on how to do this...if possible.
MoBo=P6NGM2-L
Bios v2.2
CPU:Intel Pentium Dual Core E5200 Processor BX80571E5200 - 2.50GHz, 2MB Cache, 800MHz FSB, Wolfdale, Dual Core, Retail, Socket 775, Processor with Fan.
I'm told this should be done within the BIOS but can't find that feature.
I know this takes away from it's ability but I require it to be single core until I can get a new different PC single core setup
Thanks

I am not sure I am quite getting the point of doing this, as Single Core Operations usually just run on one Core to begin with and you should be able to restrict that application or service to one Core by simply using the Device Manager.
You cannot really turn off one of the processor's cores independently. All you can do is to trick the operating system into believing that there are no two cores. Usually, you would do that by forcing an uni-core HAL during Windows Installation.
Which Windows Version are you using? If you are using Windows XP, set MPS Table Version to 1.1 in BIOS and see if XP is able to automatically adjust to the changes. In Vista, there is an advanced Boot Option named "Re-detect HAL" or something like that.
If you are using XP, have a look here:
http://support.microsoft.com/?scid=kb%3Ben-us%3B309283&x=&y=
Your current HAL should be ""ACPI Multiprocessor PC," ACPI APIC MP HAL (Halmacpi.dll)". Changing the MPS Table Version (MPS = MultiProcessor Specification) from 1.4 to 1.1, should yield the ""ACPI Uniprocessor PC," ACPI APIC UP HAL (Halaacpi.dll)" HAL.

Single Core MBP

Let's see, I have resorted to installing the developer tools and going "core solo" to get rid of my CPU hiss. Naturally, now I'm wondering how drastic the performance defecits are. Anyone have any idea?

I guess you could get hold of one of the various benchmark programs that people run to test performance and then run these with both single and dual core and see the difference.
In the real world, it's entirely your perception that matters. If you feel that performance on a single core is adequate for your needs and makes you feel comfortable due to lack of hiss then that's all that matters. If you are doing a processor intensive task (e.g. encoding video, working in iMovie, etc.) then you could just consciously enable the second core at that time to get more power, the hiss won't be there at such times due to high processor activity. Once the task is finished, you can disable one core again.
I personally think it is regretable that users pay good money for a "pro" dual core machine and then have to resort to crippling the full potential of that machine in order to work effectively and peacefully on it. Alas, we all have to do what it takes to achieve peace of mind. Enjoy your silent single core computing experience!

Possible to flash bios on k8n neo2 platinum without single core athlon64?

Hi.
I just bought a k8n neo2 platinum v1 and also managed to find a decently priced athlon64 X2 3800+ (which should work fine with this mobo according to msi's website and a number of forum posts I've seen across the web). The cpu hasn't arrived yet, but I'd appreciate if someone could answer something I'm wondering about before that happens. I've read that the mobo (like many others) will need a bios update to use dual core cpu's. A problem I have is that I don't have a single core athlon64 to use for flashing it. I did read on several forums and in some articles that a lot of mobos would be able to boot the dual core as a single core without the bios update, in which case I should be able to flash the bios with a boot disk, or similar. However, it occurred to me that it may only be nforce4 mobos that could do this.
Now, I'd really appreciate if anyone knew whether I could flash the bios with the dual core working as a single core, or if I have to start looking for a single core athlon64, to use for that purpose alone.
Thanks in advance!

Finally got it assembled (after having to order a new fan, since I couldn't get the old one to work)!
It worked to boot without flashing first, the BIOS recognized the cpu as an unknown hammer cpu. After flashing (which went without any sign of trouble), I'm now up and running
Thanks for the help :D
Tried to used the CPUZ to check on the cpu version? Cos dual core doesn have a hammer but manchester only. Gd luck.
