Does the 15" 2014 GT 750M model drain battery faster than the iris pro version?

I can't decide between the 750M model or the iris pro model. I've heard the GT 750M is not worth the additional price
as it drains the battery much quicker, is this true?

The 15-inch MacBook Pro with the NVIDIA GeForce GT 750M also comes with an Intel GPU, which is the same GPU as the model without the NVIDIA GPU.
This means that the battery life will be the same in both models with tasks that do not require higher GPU performance (home tasks). The NVIDIA GPU is enabled when you need more performance, so you do not need to worry about that. However, as the NVIDIA GPU is more powerful, it needs more power, reducing the battery life when it is being used

  • Is the Core i7 processor comparable, much slower, or faster than the 2.8 Ghz core 2 duo from 2009?

    I am looking to get a new MacBook Air, but when looking at the prices I am seeing the MacBook Pro 13" for the same price and a lot more guts (RAM and Processor).  I am ok with spending the amount of money on the air if it means I get a computer that is like my iPad, which i love (flash based, snappy), but don't want it to be super slow.
    I am coming off of a 17" 2.8Ghz MacBook Pro from 2009.  I was happy with the speed and power of that machine.  The most taxing thing I did was make a complilation of family movies in iMovie and burned them with iDVD once in the 2 years of ownership. 
    I mostly browse the internet and compose written documents, and keynote presentations.
    I know my questions may seem stupid, but I don't know how significant the changes between i7 and Core 2 Duo are, so I ask the question:
    I am wondering if the processing power in the core i7 will be somewhat comparable, much slower, or faster than the 2.8 Ghz Core 2 Duo I had in my 2009 computer?
    Thanks for any help!!

    Hi brosephb,
    Like you I went through a similar comparison process. I bought the MacBook air 13" and up specced the processor and memory. I don't do anything taxing enough or frequently enough to NEED the extra power of the MacBook pro.
    I am overjoyed at my air. It's gorgeous, the way it wakes instantly, it's speed and it's portableness is so endearing that I just don't use my iPad anymore. I read numerous reviews on it and the overwhelming opinion was it's addictive ease of use because of it's slim, light and rapid waking. At work I can hold the air with one hand, open it rapidly at will. It's just great but it's made my iPad redundant (for me anyway).
    I see the new airs are even faster and I'm tempted to consider selling my 6 month old air and getting the new one, but, it runs a dream so I am happy to just be envious of the new one.
    In short, unless you need the power (for your work) go for the air. I'm looking at a new iMac to use as a home work station. For the price of a new air I can get an iMac that will swallow any task for a good few years to come. And my air will suffice as my mobile companion. However, that's just me spoiling myself as, at the moment, I have no teal need for another mac. I may get the cinema display for any long winded tasks, as the screen size will help with multiple tasking.
    A bit of a ramble, hope this is useful.

  • I read on the website that the update 4.0 was supposed to work faster than the last but I that since I updated (2 days ago) my work in firefox has become quite sluggish. Any suggestions?

    Hi there. I upgraded to firefox 4 on Monday (two days ago) since I saw that the new version was supposed to run faster than firefox 3 that I was using. However, since I've started using it, I wait longer for a page to download than I had to before and the whole browser just is sluggish to respond. Any suggestions?

    Sounds like it either believes that there are headphones plugged in, or the switch is broken.
    Why in the world would you take it to Best Buy for service? Take it to an Apple Store. They can replace it on the spot if it's defective.

  • IPhone 4S draining battery faster than it's charging

    So, I, like others, have had issues with my iPhone ever since upgrading to iPhone 6.1. I went to an Apple store, and because the connector dock was acting strange they said it might be a hardware issue. My phone basically bricked after that, and was dead for 2 days, but for some reason I kept it plugged in, and out of nowhere I had enough charge to restore it (via iTunes, using the restore method rather than a simple restore). After that it charged to 100%, just like normal.  I went back to the Apple store, they tested the battery and said it was running perfectly. I asked if I can start putting apps and stuff back on, they said yes, I did, and now it doesn't charge past 70%. I restored it once again, and now it won't charge past 65%.
    Can I blame this on 6.1, 6.1.1, and 6.1.2? or is there something I should do that might fix this? I've used multiple cords and chargers.

    Hi guys,
    Click «about this mac», in the apple menu, and then click «more info». This will open the system profiler window where you can see in more details the actual state of the battery, if you highlight it in the left column (probably under «power», I don't know because my system's in french, sorry). My remaining capacity at full charge is around 4900 mah (it was at 5200 when I first got the Macbook), and I'd say I get about 4,5 hours if I'm very careful. If your numbers are way under this (providing the number of charge cycles is reasonable), my guess is you have a bad battery. Good news is you're covered by AppleCare.
    See this thread for great insight into battery life, etc: (see the post by macbook7)

  • Why does Magic Mouse use much more battery power than the keyboard?

    I have the Bluetooth versions of the keyboard and the Magic Mouse. I use the same rechargeable batteries in each. Yet the mouse has now come to the end of a THIRD set of AAs, while the keyboard still has 60% of its first set.
    Why? They are both constantly in use, so why does the Mouse drain batteries so much faster than the keyboard? Viz: the mouse about once a week (two, max), while at this rate, it will be another month or more before the keyboard drains.

    Actually I don't! I consider myself a 'power user' in that I will always use the keyboard first, and I learn keyboard shortcuts for nearly everything I do regularly.
    I would guess my use is 50:50 at worst?

  • Is the iPad 3 faster than the iPad 2?

    Hi,
        Is the iPad 3 faster than the iPad 2? Also, how much better resolution is the iPad 3 from the iPad 2? I was just wondering because I heard that the new iPad isn't worth it's price.

    The New iPad is not remarkably faster, but does have a faster chip, which is required to handle the amazing Retina display.  The new display on New iPad is without question significatly better than iPad 2 and offers nearly 4 times the resolution of iPad 2.  Whether it's important to you, only you can know.  To see the difference, go to an Apple store where they still sell iPad 2 and New iPad.  For me, the difference was night and day, which is why I sold my iPad 2 and upgraded to New iPad.

  • Is iPhone 4G 32GB faster than the 16GB?

    Is the iPhone 4G 32GB faster than the 16GB? Are there any other advantages to getting the 32GB (other than memory size)? Thank you.

    Daniel Wasinger wrote:
    Thanks very much. A friend who bought the 32GB said it has more ram and is therefore faster. But I was skeptical
    As Track607 stated, you guys have no idea the difference in terms.
    Memory is RAM, and is NOT the same as STORAGE. And no, it's not "the same difference", it's completely different.
    Also, to add, the iPhone does not have the capability to use virtual memory, thus, the iPhone could have 64 gigs of storage, and it wouldn't run faster. Your friend does not know about computers. Don't ever let him help you pick out a computer.

  • Audigy2 NX :Sampled audio is faster than the origi

    Sampled audio at 6 bits is faster than the original soundtrack
    I'm using Sonar 2.2 and when I use My Audigy 2NX USB2 with 2 audio tracks,
    I'm recording on the second one while listening the first one :
    -No problem with my AC/97 sound card
    - Problem occur with my audigy 2 NX (Sampled audio becomes faster (Timing not adequate) while listening to the recording , the first 0 seconds seems in exact timing, then after I feel that the recorded begins to take speed and then ends second before the track one !!!
    I Solved the problem partially by using CoolEdit instead of Sonar and in the Setting-Multitrack Tab, i activated "correct for drift in recording"
    Please Help !!!

    First try to play your video on the PC. Use Quicktime 7 and it should work.
    If it does the same thing on the PC then the video encoding has created this problem. Nothing wrong in the phone. You will need to re-encode. May I enquire as to which software you are using to encode?
    If it plays correctly on the PC then your best bet is to lower the bitrate or the frame rate of the video, re-encode, transfer and try again.
    I recommend using h263 as the video codec as this will be "safer" to use. Try 3gp extension format as well.
    640K Should be enough for everybody

  • The 15-inch unibody is faster than the 17-inch unibody flagship?

    Macworld benchmarks has the 15 edging out the 17.
    And that is Before yesterday's speedbump for the 15.
    http://www.macworld.com/article/139139/2009/03/unibody17_inch_macbookpro.html
    When they remeasure, will the 15 be substantially faster than the 17-inch flagship?

    Historically, the 17-inch has been faster and better in many ways.
    I'm sorry, but this is simply incorrect. I will present for you the following specifications from every MBP revision. All specifications represent the high-end 15" and stock 17" of the time which are the two models we are comparing here.
    MacBook Pro (Early 2006, Original Revision)
    15.4"/2.16 Ghz (CTO)/1 GB RAM/100GB/256 MB VRAM/$2499
    17"/2.16 Ghz/1 GB RAM/120 GB HD/256 MB VRAM/$2799
    Macbook Pro (Late 2006)
    15.4"/2.33 GHz/2 GB RAM/120 GB HD/256 MB VRAM/$2499
    17"/2.33 GHz/2 GB RAM/160 GB HD/256 MB VRAM/$2799
    Macbook Pro (Mid 2007)
    15.4"/2.4 GHz/2 GB RAM/160 GB HD/256 MB VRAM/$2499
    17"/2.4 GHz/2 GB RAM/160 GB HD/256 MB VRAM/$2799
    Macbook Pro (Early 2008)
    15.4"/2.5 GHz/6 MB L2/2 GB RAM/250 GB HD/512 MB VRAM/$2499
    17"/2.5 GHz/6 MB L2/2 GB RAM/250 GB HD/512 MB VRAM/$2799
    I think it is pretty evident that in terms of clockspeed, RAM, and VRAM the 15" and 17" have never been too far apart. I don't think 20-40GB of HD space is all that big a deal. Yes, the 17" has had an extra USB/FW port. I don't know if these things qualify as "faster and better in many ways" though. Really, the most significant way that the 17" was "better" was the screen size and resolution as has already been mentioned. Things are no different now than they've been for the last three years. I don't know what they were like in the PPC days because I don't have time to look back that far, but I don't think it matters.
    In fact it's slower, and will seem even slower with the 15's speed bump.
    It's not slow at all. In fact, it's one of the fastest notebooks that you can buy at all right now. We have already pointed out that you shouldn't take the benchmarks seriously because they have absolutely no statistical significance.
    These things are not going to change. If you need the notebook now, you should buy it. If you don't need it, then wait. If you don't want it, then buy something else.

    Which version of the OS is installed, and which version are you trying to install?
    You could try starting up with Startup Manager and see if it will allow you to select the OS X install disc as the startup disk. If so, maybe you can proceed from there. I would recommend repairing the hard drive first since you are evidently having a bit of a problem with it.

  • Can the WD Raptor make my 2.0 Dual faster than my new 2.3 Dualcore?

    A few weeks ago I had asked what would make my machine at work - 2.3 Dualcore w/2GB of RAM - slower than my home machine; 2.0 DP w/2.5GB of RAM.
    The new Dualcore was unreasonably slow and I followed the few suggestions to wipe the drive, which brought it up to snuff... but I still find it slower than my 2.0 at home. At simple tasks (contextual menu pop-ups, software loading, etc...) as well as more complex Photoshop and 3D tasks.
    It's not the very last generation 2.0, but the one prior, e.g. 8GB of RAM capable, PCI-Express, and liquid cooling, etc...
    I doubt the .5 of RAM can make that much difference, is the WD Raptor the difference and am I just spoiled by it?
    Thanks for any suggestions.
    -Vincent

    So you have a Raptor as boot in your home based Dual Processor and it seems faster than the faster Dual Core you have at work.
    That's understandable, especially since the Dual Core most likely has a 7,200 RPM 250 GB slow drive (and more filled being at work, using more fonts?), plus the Dual Core shares a fronside bus, unlike the Dual Processor which has one for each. Photoshop pre-CS2 swaps memory to disk, so a faster boot drive will help. (Tiger overrides CS2's RAM limit, so more RAM will give better performance)
    At home you have the Raptor as boot and most of your user files on the second drive I'm assuming, allowing you to access two drives at once using two busses.
    Of course CPU intensive tasks the Dual Core 2.3 should beat the Dual 2, but since Mac OS X is heavy boot drive speed dependant (caches, swaps etc) the "User Interface feel" should be more responsive on your Dual 2, giving you the impression it's faster.
    Big fat filled slow boot drives really cripple Mac OS X performance (NAND RAM coming?)

    **** little info about your equipment.
    If you just replaced the router with an Airport Extreme or Express:
    disconnect the modem from power, disconnect the new router from power, connect the modem to power and wait till it os fully started up, then connect the new router to power. After a while the amber light will turn to flashing, then after a while it will turn to green. Then with AirportUtility (in Aplications/Utilities) it should be configured with the password.
