Graphics card a bit more powerful in 15" than 17" due to lower resolution?

Is the graphics card a bit more powerful in the uMBP 15" than in the 17" due to the lower screen resolution? E.g. for games. I notice that when I turn down the maximum resolution in a game, the playing is smoothier which is logic but still, does that give the graphics card a bit more performance? I mean, I know they are the same in both the 15" and 17", it's just that the lower screen resolution might give a little more power to spare e.g. for framerates.

It doesn't mean it's more powerful... it's identical. If you run the 17" at a lower resolution (as in the same resolution as the 15"), you would get similar performance to the 15". Running at a higher resolution requires more processing power. Likewise, if you plug in an external monitor to a 15" which supports the same resolution as a 17", you would get similar performance on the 15". The difference is purely based on the resolution you choose.

  • HP 15-g073no two gfx cards, how to choose the more powerful one?

    Hello! I am a brand new owner of the HP 15-g073no laptop! So, my problem is, how does one switch the preferred graphics card to the more powerful dedicated card with 1gb of dedicated RAM? Also, can I use the dedicated graphics card on the laptop monitor, or do I have to plug a screen in through HDMI?

  • HP 500-054 problem with graphics card

    I just bought my HP 500-054 PC and also bought an upgraded graphics card and a more powerful, power supply to run the graphics card...to the best of my knowledge the graphics card (XFX radeon R7770 ultra OC edition) is set up properly in my PC and connected to the new power supply. If i try to boot from the new graphics card nothing displays on my monitor and the PC just beeps 3 times. If I boot from the onboard graphics card then everything works like it should. I'm wondering if anyone has advice on this if maybe i set up the graphics card wrong or if there are settings on the PC I need to change. Any help would be greatly appreciated

    Hi:
    Your second assumption is correct.
    There are settings in the BIOS you need to change when installing an non-HP video adapter in a PC with W8.
    Please read the info at the link below and you should be all set after following the guidance there.

    Unfortunately, the GPU is not upgradeable in these units.  You would have to upgrade the entire motherboard package, which would be costly and cause potential reliability issues in the future.  Your best option would be to upgrade to a newer notebook with the GPU and specs you require.

  • Tesla Nvidia Supercomputing graphics card on MacPro

    There are lots of cards that Apple doesn't support. The terms of use on these forums is "technical" questions. Short: no EFI firmware.
    When Microsoft Vista 64-bit moves to EFI 2.0 there might be more options. Right now, what you see is what you get.
    Why not the Radeon X1950 or X2900?
    Or FX4600 and others? Nvidia wants to see more offloading of work done on CPU would be more efficient if it was done and stayed on the GPU for Final Cut and other programs.
    NDAs are just that, do not discuss, Non-Disclosures. Any engineer or working prototypes out there are just that. Putting up a banner was enough to get shot down.
    Rumors and there are sites that trade in such currency.

  • Do I need a dedicated graphics card for my laptop if I mainly use Photoshop CS6 to paint?

    I'm looking to buy a laptop and having a dedicated graphics card is obviously more expensive, but is it necessary for painting on Photoshop CS6 without lagging? I use a lot of layers, adjustments, masks, and large brushes, but that's mostly it, also I don't spam the undo button.

    LOL, those are very compute-intensive operations.  That's basically saying "I need the most powerful computer I can find" to run Photoshop.
    It's hard to generalize an answer to your specific question, because not all GPUs or systems are created equal.  If I had to generalize, I'd say you should try to avoid DUAL GPU systems, in which an Intel and some other brand are combined to try to deliver power saving and high performance capabilities.  Photoshop traditionally doesn't really like that kind of arrangement, and forum members often advise folks with dual GPU systems who are experiencing problems to just disable one of them (usually the lesser one) anyway.
    Keep in mind that a laptop isn't going to be able to achieve as good performance as a desktop for a resource hungry application like Photoshop, yet will be more expensive.  You really will want a high-end machine (possibly even mobile workstation class) to paint in the manner you describe.
    I invite others who use modern laptops to chime in here and relate their actual experiences, as well as provide information on their specific configurations.

  • Multiple graphics cards on 2008 mac pro, won't work

    Hi, I have a 2008 Mac Pro 2 x 2.8 GHz Quad Core Intel Xeon with 14 GB 800 MHz DDR2 FB-DIMM. I have used a ATI Radeon HD 2600 Graphics card connected to 2 x BenQ E2400HD screens. Now, I want 4 screens so I bought a NVidia Geforce 8800 GT graphics card as I found these to be compatible with my setup on Ebay (only place I could find it). Got it in a brand new condition in a Apple graphics card box so should be all good. Put it in PCI-E slot 2. Now when I started my Mac after installing I could hear a loud fan noise (fan going on max speed) and tracked it to the new graphics card. When I open the system profiler it shows up as a display. The screen connected to the graphics card with a DVDI-cable does not show an image and the screen indicates that it does not have an input. Any ideas what's wrong here? Is my graphics card broken?

    More than likely you got wrong verion.
    1,1 and 2,1 Mac Pros are EFI32, and for Nvidia cards need proper version.
    If your machine is a 3,1 or later you need an EFI64 version.
    Contact the seller and clarify.
    If you install "ATY_Init" and are running 10.6.8 you will find the card will work once machine boots all the way.
    You could then flash the card into proper version if you were especially clever with things like that.
    But your seller should help you.
    You need to know "Model Identifier"

  • Does CS5 require a discrete graphics card?

    My computer has a Core 2 Duo and 3GB of memory, but only onboard graphics. The CS5 Design Premium system requirements include "qualified hardware-accelerated OpenGL graphics card, 16-bit colour, and 256MB VRAM". Does this mean I cannot run CS5? Or does it just mean that if I want the benefits of a graphics card, the card must meet those requirements?
    I expected to be able to answer this question myself with a bit of web searching, but haven't been able to! Thanks in advance.

    Thanks Bob, I'll go ahead and try it. As it happens, Photoshop is the part of the suite I anticipate using the least.
    It's a shame the literature is unclear, though — I understand "requirements" to mean exactly that: a minimal specification without which the software will refuse to install. A graphics card could be on a separate "recommended" list.

  • Please Help - Screen corruption while in Aperture - graphics card problem?

    Over the past few weeks, I have noticed frequent screen corruption within the confines of the image that I am currently editing. The corruption only occurs when in Aperture. The corruption occurs as multiple thin (one pixel?) horizontal lines of random color and random length that occur in random locations within the image. If I force a re-calculation of the image (such as change white balance) the random lines will disappear, only to reappear somewhere else. The actual image (after export) is never corrupted, only the display. Recently Aperture has started to "hang" in random ways, sometimes freezing the whole machine, sometimes crashing, sometimes beach-balling.
    This sounds like a hardware problem to me, but the standard Apple hardware test runs without errors, as does an extended memtest. Setup: Mac Pro, 5GB, SW fully updated to 10.4.11 and Aperture 1.5.6. I tried re-seating the graphics board to no avail.
    Are there any programs that I can use to test the Radeon X1900 card?
    Any other suggestions?
    Thanks in advance.

    Thanks David,
    I did some more research and it appears that quite a few of us (unlucky) users with an early version of the Radeon X1900 graphics card are now seeing failures that appear to be due to poor heat dissipation by the graphics card. There's a huge thread on the subject here:
    http://discussions.apple.com/thread.jspa?threadID=1195969
    The problem with random display glitches doesn't show up for most people until they upgrade to Leopard, which puts a larger strain on the graphics card than Tiger. I am still running Tiger, but the glitches show up for me when using Aperture, which of course uses the graphics card more aggressively than most other programs. I assume that Aperture increases the heat which causes the glitches.
    I tried cleaning the dust out of the Radeon's heat sink, and I added a tool (smcFanControl) that lets me manually override the default fan speed. By keeping the card's temperature lower, the glitches have gone away. If I let the temperature rise, they come back. Looks like I'll be needed a new graphics card.

  • Graphics Card Error message...

    Hello,
    I am experiencing a recent problem with my newly purchased MacBook Pro. (2.4GHz Intel core 2 Duo)
    I have FCP 4.5HD and after transfering it over to my new machine I am unable to launch it. At launch I get the error message: "This software requires certain hardware or software which is missing. -- AGP graphics card. "
    It seems to me that there is a graphics card issue, but I would assume that a new MacBook Pro's graphics card would be more than sufficient and compatiable with a highly popular editing program not to mention they are both Apple products.
    Would you be so kind as to stir me in the right direction? Why exactly am I experiencing this problem and what can I do about it.
    Many thanks,
    Karchi

    This is because FCP 4.5 was designed for the PowerPC processors, and you are using an Intel processor. FCP 5.1 was the first version designed to work on an Intel machine.

    You either need to either:
    1) use the following hack -

  • Question about graphics cards for Equium L40 - 10X

    Hi - new to this but really hacked off so hopefully someone can help me.!
    I bought a Equium L40 - 10X in August and thought it was good for what I wanted, especially after seeking advice and speaking to 'an expert' at my local pcworld.
    However, I think the graphics card is not good enough to support the games I have got - Medal of Honour Warchest, Hitman Triple Pack and Call of Duty 2. They all sem to recommend a nVidia graphics card as a minimum requirement. The card in the laptop is an Intel(R) 945 Express Chipset Family (I think) and the OS is Vista Home Premium.
    Problems I am experiencing include loss of graphics and stuttering during play.
    Can I upgrade to an nVidia graphics card or is the one I have got sufficient but I just need to change some settings?
    Haven't got a clue really, so help would be much appreciated!

    > I bought a Equium L40 - 10X in August and thought it was good for what I wanted, especially after seeking advice and speaking to 'an expert' at my local pcworld.
    Either you was not clear enough or the expert from pcworld have provided the wrong information and wrong advice.
    Fact is that the Intel shared GPU was not really designed to play the newest games.
    The shared graphic card is simply not powerful enough to run such games smoothly!
    > Can I upgrade to an nVidia graphics card or is the one I have got sufficient but I just need to change some settings?
    NO, this is not possible because the notebooks graphic cards are fixed on the board and cannot be removed.

  • How do I know if my graphics card is bad?

    I'm having some trouble on a couple of websites with graphics. It's hard to explain what is happening visually, but it appears that the screen gets "blocky" and the blocks move around as I move my cursor. Or, portions of the screen turn white. Sometimes portions of the screen "pixelate." This has happened only on 2 websites and not with any games (although I don't run high intensity graphics games) or other programs that I run. Is there a way to check the graphics card? I purchased the computer less than a year ago so it still should be under warranty.

    Take pictures of these web site displays and then make an appointment at an Apple store genius bar and have them evaluate your MBP.  Naturally bring the pictures with you.
    Ciao.

  • Why ABC's are more powerful 'interfaces' than interfaces

    A simple answer as to what the value of Abstract Base Classes are is that
    (1) They act like Interfaces, allowing for polymorphic abstraction of multiple implementations
    (2) They allow for default implementations, but insist on derivation
    For this question, please set aside any value that default implementations provide, and concentrate only on the 'interface'-like qualities of ABCs.
    Why did sun decide to make ABCs more powerful as interfaces, than interfaces themselves.
    Or... asked another way, in the following code snippet
    public void doCoolStuff( ObjectOutputStream os, Fooable foo )
    throws CloneNotSupportedException, IOException
        Fooable foo2 = (Fooable)foo.clone();
        foo2.changeMyselfSomehow();
        os.writeObject(foo2);
    }If I said the Fooable 'thingy' has absolutely no implementation attached to it whatsoever, then, what kind of thingy is Fooable?

    Functionally: A class can only extend one class,even
    if the parent is an ABC, but it can inherit multiple
    interfaces. public class Foo extends ABC1,ABC2
    {} // won't compile
    Yes that's the common logic. And yet Fooable
    absolutely can not be an interface, but can be
    an ABC.Interfaces can do X that ABCs can't do. ABCs can do Y that interfaces can't do. Which is more powerful?
    This box is longer, but that box is wider. Which is bigger?
