AMD dual core 4200 2.2 vs i7 2.7?

Besides the obvious, what's the difference between these two processors. Is there a significant power gain from the i7?
I have a PC running the AMD chipset with 3 megs of RAM and just bought a MBP 13" with the dual core i7. What kind of performance gain am I going to see?
Thanks!

I don't have both yet. Just ordered the MBP on a leap of faith. Hopeing the i7 is a much faster processor.

  • Unexpected reboot during simulation using multisim on AMD dual core processor

    We are using NI-multisim 10 in a classroom environment and are experiencing sudden reboots during simulation without giving any error or warning. This happens on multiple machines, all being Dell Optiplex 740 with AMD DC 2Ghz as processor. Since these problems happen so frequently, making  teaching quite impossible, we have shifted PC-room and are now using older machines. On these machines - Dell GX280 using intell P4HT-2,8 Ghz - we experience no more problems.
    Is this reboot problem related to the article :  Unexpected Errors with DAQ Device on AMD Dual Core Machine  (http://digital.ni.com/public.nsf/allkb/9CE22FE099A​FB8BF862572FF007A5D45) and what do we have to do to fix this problem?

    Nic
    Can you verify your driver versions? Make sure that you are running the latest versions of NI drivers to ensure proper compatibility. If possible, you might try upgrading to multisim 11. If this does not solve the issue, try the single processor workaround in outlined in the following KB:
    http://digital.ni.com/public.nsf/allkb/D0FC3BE7D9F​331398625731A005D76B8?OpenDocument
    Altough it is surely decreasing the performance of the system, certain cases have shown that there is no other possible workaround unfortunately.

  • AMD dual core 64 X2 and Opteron 1**; what motherboard.

    Hi to everybody, my name is Mauro and I am Italian. I have had for many years a lot of mobos MSI that are shown always reliable and with really excellent utility. An example the LiveUpdate that unlike utility of other brand is very comfortable and reliable. Currently I have a system AMD 64 X2 3800+ stepE4 with Asus A8N SLI Premium and memory RAM G.Skill PC4000 (chip Samsung UCCC) F1-4000USU2-2GBHZ PC4000. I have many problems of stability and I would want to return to the brand MSI. I use the PC as Workstation I am not interested to the SLI and I would want soon to pass to the CPU Opteron 1 * * dual core. The customer care G.Skill has reported that the brands of reference for the development of the forms are the MSI and few others. You would know me to suggest a complete mainboard in the endowments, silent and compatible with the CPU from me you quote. How VGA I have both chip ATI X700 Silent Pipes 256Mb or NVIDIA 6600 always silent pipes 256Mb. I am not interested to overclock. I am observing with attention the RD480Neo2 and other mobo with chipset NForce Ultra K8N Neo4 Platinum. Thanks for your share and suggestions.

    Skippy, that's changing fast. Probably most major manufacturers are now explicitly supporting the Opteron.
    Even MSI is getting there: K8N Diamond Plus
    Hi,
    To a careful study I have discovered that perhaps my Asus A8NSLIPremium has a problem that Asus is resolving. However I have asked to one friend of mine to make a will the MSI K8N Diamond Plus; in Germany it is already available some exemplary. The fact that the development has been made really with the Ram DDR that I have purchased (the G.Skill PC4000) it is a very important factor for the stability of a system. You introduces then with a good section of feeding to 4 phases it is very important. Certainly I am not interested to the characteristics of overclock but a Ferrari is not purchased only for racing. I have not told you that in so many years I have almost always had 2 brands that have always guaranteed me reliability: Abit and MSI. Objectively now that have tried also a lot of Asuses (5) I are not fully satisfied. For instance the Utility: LiveUpdate2 gave me reliability in the update of the bios (operation that finishes in DOS); the utility AsusUpdate because of a bug in the summer '05 are cost me 3 MB (update that departs in auto and it finishes in Windows). Resulted not could remain without MB I have had to purchase other identical MB. And treating itself of corruption of bios no guarantee. I have also discarded Tyan because it accepts only certified RAM DDR and their support it doesn't guarantee the operation with my DDR G.SKILL. Now that are in game I don't sell certain the DDR!

  • AMD Dual Core Processor - Problem between tracks

    I am running iTunes on a dual core AMD Athlon processor and notice strange behavior on the computer. When iTunes moves from one track to the next, it sounds like it is playing the end of the first track at the same time as the beginning of the second track. The same mp3 files play perfectly when downloaded to the iPod.
    My theory is that iTunes is using only one processor on each file (track) but can switch to the other processor for the next track. Since they are asynchronous, they end up overlapping during the transition.
    BTW - latest drivers, including the May '06 AMD driver are installed.

    There's no need to worry, it's just a neat little feature, not a hardware issue. Some people like it.
    In iTunes, go to the Playback prefereences (Edit>Preferences>Playback tab) and make sure "Crossfade Playback" is deselected.

  • Dv6710 Vista amd dual core

    Hi guys and girls
    i know there is a massive problem with the DV series  with the wifi  as well as other stuff
    Well  my problem is that my wifi is working fine   and i can get on the internet with no problems
    but i cannot get the orange light to turn blue once windows is loaded
    It  stays orange until just before windows kicks in  then the orange light goes out but my wireless assistant says its still on and i get on the net okay
    when the screen dims itself after a while  the screen goes into sleep mode or what ever it does and the orange light comes back on
    but as soon as i run my finger across the touchpad  it goes out again the the wireless is still working
    i have tried every wireless driver that i can find
    also when i uninstall the driver  the orange light stays on for both on or off positiion using the wireless switch
    Has anyone come across this before   or have any suggestions please  ????
    Also  on the keyboard  all is working well apart from when i press the Capital lock key  the light does not come on
    many thanks
    maggie

    I asked AMD Support just that question, plus clarification on the driver situation, and their response was to just use the 1.0.8.1 PowerNow/CnQ driver with X2 CPUs on Win2K.  Given the slow uptake on Windows Server vs. the client systems I'm surprised they did not continue Win2K Server support for longer, in a market which is so important to them.

    We kind of need the full model number. Yes to the SSD for sure, but just want to check the specs to be sure you can install up to 8 gigs. Very likely yes on the memory, too. 

  • K9NGM Dual Core Problem

    Hey guys.
    Seems I have the same problem as the OP. Everything on the system says that dual core should be working, ACPI multi installed etc but only 1 core in task manager. Im going to try roll back the bios because the dual core was working before I flashed it. Thing is I only have the MSI download version of 7252v31, which apparantly needs to be used from a dos enviroment, hence needing a boot floppy to construct a ramdrive etc..(I have no floppy drive).
    The 7252 v3.60 latest driver has a little MSI install program to let you install through windows (MSISetup.exe). Is there a way of installing 7252v31 through windows, or can i just use it through a dos window in XP.
    If anyone can maybe link me to a windows installable version of the last bios update before 3.60 (which is possibly the update that has caused this problem) I would be most grateful.
    Also, will I have to go in and reset the CMOS manually?, or should the update program clear it for me (as it appeared to do when I installed 3.60 with the MSI exe).
    Thanks very much for any help this is driving me nuts.
    PS: Yes I am a very bad person for flashing my BIOS when i didnt need to. Lesson learnt.

  • Which dual core to buy ?

    Which is the best option, Opteron 165 or X2 4200+ (considering that they cost the same) ?

    Quote from: decalpha on 07-March-06, 14:31:24
    Just one more doubt, will my current Mobo. cause problems while o/c 165   
    Looks like youré going to be fine with a 165 opteron in combination with your MoBo / bios.
    I would recommend a hdd format / new Win XP SP2 installation to recognize both cores and get best performance.
    There is an AMD dual-core driver and a MS hotfix as well that could be used if you´re experience any kind of instability.
    PSU looks fine and should deliver stable power and not set any limit for your OC adventure.
    Don´t know what mobo/cpu fluctation you can expect on the K8N SLi Platinum board, but I got some 0,03v on my K8N Neo2 and it still handle a stable decent OC on my 146 single opteron.
    As for dual-core cpu, I have an X2 3800+ on a DFI LP NF4 mobo overclocked to 2700mhz prime95 stable with both cores. It is powered by a Tagan 480w like yours. The cpu fluctation is practically 0,0 when running OCCT test.
    Starting OC you probably already know there´s some bios setting that usually needs to be changed.
    HT 4x or 3x depending on what "FSB" that is used ( HT 4x up to 250 and HT 3x above 250 )
    The 165 has a low 9 multiplier which means you probably need to run very high "FSB" and use the HT 3x option if your going for higher OC ( compared to the X2 4200+ that has a 11 multiplier ) and for memory setting you will probably need to use at least 166 divider or even lower depending on what memory quality you´ve got ( only says 2x512 in your sig.)
    I would also recommend running memory at T2 setting for best stability if you´re aiming for the higher OC numbers.
    Then you have to find out what vcore ( ex.1.4v) and vdimm (ex.2.75v) that needs to be set for OC and some other things as well, but you could always read more about the details here ;

  • K8T NEO2 dual core upgrade problems

    Hi Everyone hope someone can help here I have just purchased a dual core 4200 socket 939 for my 6702e it has been running fine on my 3200 the 4200 is the one with the 2 512k cache if that helps.
    I have the latest bios through msi update think 9.40 so here is my issue. As I have stated this runs no problems at all with my single core 64xp but once I put the new processor in no boot or anything not even an error beep, all the indicator lights on the back panel go amber. I have cleared the cmos and installed 1 stick in the second purple slot 1 gig still nothing.
    Any help would be appreciated and thanks in advance.

    Quote from: HenryW on 28-March-08, 09:46:59
    Is the X2 4200+ new or did you buy it used from eBay or some such? What does it show for BIOS version at the upper left when you boot the PC? I ask this just to confirm you do indeed have 9.4 BIOS.
     Make a signature with PC information. Also include specs for PSU from label on it, see my sig. example of what info to provide.  By making signature your specs will show in every post you make.
    To create signature:
      Click on PROFILE above (near top of this page) and then in your "Profile" what I show in red below, scroll down to "Signature" and enter your specs in the box and then click on "Change profile" button on the bottom.
    Rebooted to make sure hehe yepper 9.4 bios
    Also fixed signature to the best of my knowledge.
    Thanks again for the reply and yes this is a used processor off of ebay reputable seller with no negatives so he has a DOA clause but just trying to trouble shoot this so I don't have egg on my face before I ship it back

  • MSI NEO4 Platinum + DUAL CORE detection problem after soft reboot

    I just build a new AMD dual core system (4800+) and it consistently fails to detect the second core after a soft reboot from windows Xp.  The MSI NEO4 Platinum came pre-flashed with the latest bios version 1.B.  If power off or use the reset button I can consistently get it to detect both processors.  Anyone else having this problem? Or know of a solution?
    Thanks.

    Hi, I did a upgrade from a 3200 venice to a Opty 165.[This is a different situation than your new build] I deleted the uniprocessor ACPI from the device manager before I removed the old cpu. It was a bit weird for me in that at first the bios saw it as a 165 dual core then the next time it would come up as single core. It went back and forth a few times between single and dual core in bios. I tinkered with a few things in the bios but not really sure if it helped but it eventualy stayed as dual core in bios and showes as dual core in windows. I have my MPS table version set to 1.4 in bios [ but it was this before change in cpu] also my IOAPIC is now greyed out [unable to change it, but it wasn't before] - both these are in Advanced bios features. In power management I have the ACPI standby state set to auto. Hope some of this might help you.

  • I am lookinat buying an Aspire Netbook with 4 gig ram, dual core amd c70 processor and windows 8, wi

    am looking at buying an Aspire Netbook with 4 gig ram, dual core amd c70 processor and windows 8, will it run my cs5 suite

    Mark,
    Adobe generally requires a minimum CPU clock speed of 2.0 GHz or higher in order to run CS5 or higher. Unfortunately, the AMD C70 CPU in that netbook operates at only 1.0 GHz, which is far below Adobe's minimum requirement. In addition, even if it did run Premiere Pro CS5, performance will be excruciatingly slow, not only due to the extremely weak CPU, but also due to the complete lack of a discrete GPU with CUDA capability. As such, that system, if it even runs Premiere Pro CS5 at all, would be at least 80 to 100 times slower (in terms of the Relative Performance Index (RPI) in Bill Gehrke's and Hard Millaard's PPBM5 tests) than even a mediocre quad-core desktop PC, let alone a fast overclocked i7 monster PC.

    SOLVED IT !!. You have to flash the bios to the most current version. Then i used ntune software to optimize the system and last iwnet into the bios and selected optimize settings F7 rebooted and fixed !!!

  • Old bios - no dual core, new bios - no graphic card

    Hello. I have a old computer with a MSI K8N Neo Platinum 2 that had the 1.5 bios version. I bought an AMD Athlon 64 X2 4200+ Toledo and it wasn't being recognized as it should ("AMD Hammer Unknown Model") and only 1 core was being detected. I've updated the bios and it got recognized correctly and it's Windows experience score got from 4.2 to 5.1 and it is ok now I guess. But, with the updated bios my graphic card's driver fails to load. I tested several of them both from chipset and card manufacturer's and or they fail to load or I get a BSOD 0x50 . I've tried to find a bios version that didn't blow up the graphic card driver while fixing the dual core issue but the very version that fixes the dual core issue is the one that blows the graphic card driver. And it's name is "1.9". I tried all newer bios and the same happens with all of them. Basically, or I get dual core or I get graphic drivers. This all is happening on Windows 7 Home Basic but I'm afraid will happen on any operative system if it is a bios issue. I also changed agp related configurations in the bios but nothing changes. My graphic card is an ASUS AH4650 AGP.
    Any help is appreciated.

    That PSU you have now can be bought for a little as € 5 ($ 7), shipping costs are more expensive then that
    I take this opportunity to pose another question to all of you friendly individuals that are helping me with my issue.
    As I told you, this pc is dated and I don't really need the PSU to be that future proof. I see that you have only recommended units branded Corsair. In the shop where I buy this kind of stuff there are another brands so I'll leave you the list hoping you can recommend me one that fits this system and that is a little bit less expensive in case you can find a good match. Pardon me if I'm abusing of your time.
    Site: http://www.novoatalho.pt/
    In the left navigation menu, please chose "Componentes" - "Fontes de Alimentação", and select a brand of them or press the menu itself on "Fontes de Alimentação" to get a list of all of them.
    Don't know how/if the memory I use makes it different but I have 4 dimms of 2GB combined. I was using only 1.5G but now with the new firmware the motherboard is handling 1GB + 500MB + 250MB + 250MB. The rest is hard disks and cd drives, I'm not even using a PCI card.
    If you still just recommend Corsair, is absolutely fine.
    Btw, another thing, please remember that this motherboard has a VGA slot not PCI-E. Don't know if that changes something for the PSU.

Maybe you are looking for
