    BMW M3 Level 1 Level 1 (45 points)

    Hi Jajaba, how much RAM is in your MBP?  i'm debating if i should get 8gb or 16gb.  i don't plan to do as much as you as i'm more of a casual photographer.  i do shoot in RAW though and use iPhoto, i may get another photo software to help such as lightroom or aperture.

    Okay, so after some more testing at http://www.marco.org/rmbp-irtest.html I have some minor image persistance on my LG screen (LP154 DCN24XXX). So far it's entirely invisible with my normal usage and I think I'd have a tricky job persuading the retailer there's a problem. And it's nothing like as bad as the bright pixels my previous Samsung panel had.

     

    I plan to keep a careful eye on it and if there's a deterioration I'll get a warranty replacement, which with the statutory rights in my country should be easy enough for 3 years without AppleCare, but I may just get that anyway for extra piece of mind.

    BMW ///M3, I would definitely go the 16gb route. It is only $180 more and the RAM of the rMBP cannot be upgraded by the user at a later time. I went with the 2.6,512ssd,16gb option and it is simply an awesome computer. Lightning fast and a pleasure to use. 16gb RAM is a great way to future proof it. The BMW M3 is one of my favorite cars by the way. What's your favorite model (E90,E46,E36,etc.)?

    Based on this...

    ...and your comment (above), I'm confused.

     

    All rMBP's are quad-cores, correct?

     

    P.S.

    I forgot to ask you, but how long have you and your friends had your rMBP machines?

    I totally agree. Combined with the SSD, 16GB machines are so fast. Windows XP running in VMWare runs faster than it does natively on my 3-year old work laptop.

    i7 quad cores have 8 virtual threads, so I guess technically I should have said 'threads' but most people consider them cores.  Thats the way the OS sees the i7, as 8 different cores that it can use for processing. In other words each 'core' can do 2 totally different computing tasks at the same time at full rated speed.  Just as the new dual cores have 4 virtual threads. 

     

    You can actually graphically view the activity in all 8 'cores':  Open Activity Monitor > click 'Window' on the menu bar > Then choose CPU Usage, CPU History or Floating CPU window.  Note that there are not many apps / programs that take full advantage of quad core CPU's and that's why a lot of benchmark tests show that the dual core version of the same series CPU outperforms the quad core model, basically the benchmark is only using 2 cores / 4 threads while the other 2 cores (on a quad) are idle.  Photoshop and Lightroom take full advantage of all the cores.  Below is a shot of what the activity monitor windows show while running my batch processes.  Unfortunately the much more detailed intel app that shows each cores speed, turbo boost info etc. is not available for OS X....

    PS: An easy way to max all the cores out on your machine is to open 8 games of chess at the same time and have them play computer>computer.

    Two of the other people here who have good LG screens pre ordered them in July, not sure on the build dates for the others.

    Very cool! Thanks for the clarification.

    If they've had them since July and have no trace of IR, that makes it at least more likely that they won't have IR in the future. My IR was very faint at first. However, over about a month it got very, very bad. I'm very happy with my Samsung replacement though. Zero issues and it calibrated beautifully. In any case, I honestly hope that the image retention issue is a thing of the past, because I won't be looking forward to my next Mac purchase if this is still not resolved by then. The thing that troubles me the most is that I've gone into 3 Apple stores, a Future Shop, and a Best Buy in my area, and most of the displays I've seen have IR, usually pretty bad IR. The terminal command always reports LG for the bad ones and Samsung for the good ones. That's just anecdotal, and a small sample size for sure, but it's a larger sample size than you and your friends (who in my opinion are extremely lucky). I've been following this thread since the beginning and, when you factor in the number of LG-based replacements that have also had IR, especially when the customer has exchanged rMBPs several time, it's seems statistically improbable that this IR issue is rare. It seems more probable that you and your friends/co-workers just got really lucky. Anyway, that's just my 2 cents.

    Yeah he and his friends are so lucky I don't believe it's real. How do you know he's who he says he is. EVERYONE has a problem with the LGs except him and his friends....

    I had my LG rMBP for a week now and I have no problems with it, did 2 IR test per day since I bought it and no trace of any problems so far.  It's a week 50 with french keyboard.

    Read through this entire thread and decide for yourself. That's seriously the best advice I can give right now.

    Well, I bought mine when they first came out and I started dealing directly with an Apple executive relations person pretty early on. I opted to skip the lottery and have my screen replaced. From what I've read so far, 100% of screen replacements (due to image retention) have been Samsung displays. So, if your machine is otherwise perfect, and you're not seeing IR yet, I would just keep an eye on it. Maybe you'll be lucky. If not, I think you have a better chance getting a Samsung display by replacing your screen than by playing the lottery, and it will be much less of a pain to go that route, believe me. I took mine to an authorized Apple retailer (who was also authorized to replaced Retina displays --- this is important), dropped it off at 9:00am and picked it up at noon. That was in September and my display has worked perfectly ever since.
