    Greetings guys

    So the question stands up again — should i upgrade? :)
    Currently i got 2.2 Quad 6750m 2011 mbp. Mostly using it for design purposes and gaming at home. It does quite ok, although obviously even humble games sometimes give him a run for its money and struggling on medium settings.

    So here are 2 questions:
    1. Is upgrading to integrated graphic 15 mbp would be a downgrade?
    2. Do you think i ll gain a lot of power if upgrading to top of the line mbp 15? Cant find any benchmarks so far.

    At 2880 resolution on a 15" that would kill performance, but is there a performance drop when playing on a 24" LCD connected via Thunderbolt and having the Macbook screen closed, using only the external monitor?

    Three words.

    Wait for Maxwell


    For graphics don't measure in model numbers, measure the change in architectures. You are basically one gen behind. The nvidia 650m is an architectural and speed improvement over the amd 6750m. But the 750m is only a rebadged and tweaked 650m with the same architecture. Next year nvidia maxwell architecture will come out giving a huge graphics boost.

    oh and yes Iris pro 5200 is a downgrade from an nvidia 650m/750m but not from an amd 6750m

    I really hope the new architecture isn't prone to being botched a couple years down the road like the AMD 6750M. It looks like those chips are destined for failure with a faster failure rate from increased heat.

    Sigh!

    I have the 6750 and have just started to get crashes and screen banding :(

    I dont know if I should keep the 6750M laptop... :/

    I'm hoping apple announce a repair plan like they did for the 8600m .

    The same generation iMac i.e the 2011 has a 6000 series AMD GPU with the exact same issue. Apple already have a replacement program in place for it.

    I hope they do the same for the 2011 MBP.

    Well, I'm screwed with the 6750M in my MPB, I just had mine swapped with a new logic board.

    Did it fix the problem ?

    Yeah, the laptop is fine now. Everything works. But my temperatures are still somewhat high in my opinion (50-70C via external monitor in clamshell mode with 2,700 RPM setting on fans).

    But the problem is, why should I bother with the laptop if I'm fairly confident its destined to fail again because of the lousy job Apple did on soldering the GPU? I've been told the soldering cracks. Even if thats not the case, it *IS* the GPU that fails.

    I need to skirt around this problem.

    Also, check out the differences in speed between the AMD 6750M and the Nvidia 650M:

    http://www.notebookcheck.net/AMD-Radeon-HD-6750M.43958.0.html
    http://www.notebookcheck.net/NVIDIA-GeForce-GT-650M.71887.0.html

    Crysis 2 (ultra settings @ 1920x1080)
    AMD 6750M: 12fps
    Nvidia 650M: 19fps

    Battlefield 3 (high settings @ 1366x768)
    AMD 6750M: 20fps
    Nvidia 650M: 33fps

    Call of Duty Modern Warfare 2 (ultra settings @ 1920 x 1080)
    AMD 6750M: 33fps
    Nvidia 650M: 63fps

    These are huge differences.

    My plan is get apple to replace my motherboard soonish (applecare runs out feb). Then wait at least till maxwell.

    I'd go this route myself but the SSD's in the new macbook pros are ridiculously expensive. Apple charges an addition $500 to go from a 500gb SSD to 1TB.

    Ultimately this is why I really want to keep a unibody MacBook Pro that still has an optical drive for an SSD & HDD combo (one for boot, the other for storage). I really dont want to have one drive for everything.

    I can't get on board with this advice because there's at least a decent chance that Maxwell won't see the light of day in MBPs, even though yes, it would represent a huge leap in performance over existing standards. The reasons why have been discussed ad nauseum in these forums, but I think it would be foolish for a prospective buyer to assume Maxwell will be a given.

    Yeah its a kin to saying "Don't buy the current BMW ///M3, wait for the magical turbo-less V2000 engine with 133 miles per gallon thats going to be put in next"

    Yeah. In fairness, if the advice were based on something that was truly inevitable (e.g., Broadwell), I could understand it, even though issues like timing and performance are up in the air. But with Maxwell, there's no guarantee that we'll see it at all...and I'd hate for the OP or anyone to take advice like that as gospel only to be severely disappointed later down the road.

    This could also be a Mavericks issue BTW. I don't have the thread handy, but you can google...

    Fair point its not a given.
    I look at it this way. Apple will be in the same position with Maxwell as they were this time with the 750m and Iris Pro 5200. They chose to put in both because the 5200 is slower than the 750 for games. Short of a miracle in broadwell gpu performance they will have the same decision to make next year and I see no reason to think they will change their mind on how they make their decision. If by a miracle broadwell gpu performs as well as maxwell then its a win for waiting anyway.

    It is if we knew such an engine will be ready next year.

    I agree. In all honesty I'm hoping that nvidia pulls the gap further this year rather than the other way around. But it'd be more logical to assume Intel does with their integrated chip, as has been the trend so far. Anyone know if broadwell is supposed to be as large of a step forward as Iris Pro was from it's predecessor?

    I was speculating at another incremental step simply because of profit- Intel won't be inclined to produce anything that's any better than what the masses feel is an improvement to the previous design.

    That being said, if Broadwell was 1.5x the improvement that Haswell was to Ivy Bridge, that'd be cool, I suppose.

    I'm highly skeptical to believe such traditional lines of thought. Despite typical business approaches, they have chosen to dramatically accelerate their increases in performance for Each iteration through their business plan.

    It has been a while since I've looked at this plan though and I can't remember if Iris Pro was the end of it, or close to the end. I believe that their updates have indeed been incremental, just impressive increments. It's only been more noticeable this year because of the "phenomenon" of eDRAM cache as well as it now ebbing into the mid-tier dGPU contender - category.

    Hang in there, Apple just replaced my 2.3 15" early 2011 with a brand-spankin-new Retina 2.5 for free! Granted, I've had a number of repairs inside warranty, and then a paid logic board outside warranty that then failed 3 times, which may be due to gaming, but it shouldn't fail under those conditions regardless. If you've got a lot of previous repairs, it might be worth calling AppleCare and see what they'll do for ya. Best of luck!
