Ports & Expansion

Port layout has been greatly simplified on the next-gen MacBook Pro. Along the left side there’s now a MagSafe 2 connector, two Thunderbolt ports, one USB 3.0 and one 1/8” jack for mic/headphones. The right side has the other USB 3.0 port, a full sized HDMI port and an SD card reader.

MagSafe 2 is a thinner version of Apple’s MagSafe connector, and it’s used on both the Retina MacBook Pro and the 2012 MacBook Airs. The rMBP still ships with the same 85W power adapter as before, but now with an integrated MagSafe 2 connector. In order to deal with the change in connector, Apple offers a $10 converter that allows you to plug MagSafe 1 power supplies into MagSafe 2 systems. All new Thunderbolt Displays shipping from here on out will include the MagSafe 2 converter.

The absence of an integrated Gigabit Ethernet port will surely bother some, but Apple offers a Thunderbolt to GigE adapter for $30 to accommodate. Since Thunderbolt effectively offers an external PCIe interface, there’s no performance loss if you go this route vs. the old integrated GigE connector. I was able to sustain nearly 930Mbps between the rMBP with the Thunderbolt GigE adapter and last year’s MBP:

At a price of $30 Apple is most certainly using Intel’s Port Ridge Thunderbolt controller, a cost effective single-channel TB controller without any support for DisplayPort passthrough.

USB 3.0 is provided courtesy of Intel’s 7-series chipset. Apple supports the USB Attached SCSI protocol which should allow for even better performance than what I’m showing below (with all of my focus on Thunderbolt I actually don't have a 6Gbps UASP enabled USB 3.0 dock in house):

    I insisted on a 17" laptop since the 17" MBP came out, and used them right up until I got the 15" rMBP last week. I'll never turn back. I've got it turned up to "1920x1200 equivalent" right now, and so I get as much screen real estate in a machine that's way, way, WAY smaller and lighter. And the display is so good, I'm impressed every single time I use it.

    At first, that seemed too small. I started with the 1440x900, and the next day tried the next denser step and it was okay, and the next day went 1920x1200 and it's something you get used to fairly easily. Obviously, you couldn't use 1920x1200 on a 6" screen if you had the pixel density to pull it off, but I really don't see the need for a 17" screen anymore.

    (And I use a 30" screen at work, which this laptop could easily drive if that's what I want. Heck, I've read about people driving the internal screen, an HDMI screen, and two Thunderbolt screens with a video running on each simultaneously. You don't need a huge built-in screen.)

    I am wondering how I should connect my two Thunderbolt displays to my new Retina MacBook Pro?

    a) Should I chain both displays and use one Thunderbolt port

    or

    b) Should I hook each display to its own port?

    Thanks for any advice.

    I'm pretty sure you will have to put each display on its own port. You'll be able to daisy chain other devices (disk drives, etc), but I think it's one display each for this laptop at least.

    The "classic" MBPs support both displays on the same TB port, so I would expect that to work here as well. It's mostly just a question of convenient cabling, since the displays have TB daisy-chaining outputs anyway.

    One issue though is how can the "retina display" [(FYI, 226 PPI is not comparable to the human eye which at 20/20 vision is 426 PPI) that's why I don't like Apple because they treat people like their dumb.] is that there is so much focus on the PPI.

    Ya, it's innovative (in a sense) as Apple knows how to market to the masses. But what about LED - IPS? That's a downgrade from older IPS displays. What about color contrast? Blacks/whites? What about billions of colors instead of millions? What about color accuracy and Adobe sRBG/RGB? What about glossy screens that cause over-saturated colors? Response time in MS?

    All the above mentioned are glaring oversights to the, "Best display I've ever seen..." comment. If that is the case, you should check out a variety of other displays.

    My point is that display resolution isn't everything, there are a lot of other factors that go into a good display. There are far better displays from 5+ years ago that will outperform and look more gorgeous that Apple's current 2012 model. All you have to do is go to Apple's website to see that good specifications are highlighted while poor specifications are not even mentioned.

    You do realize that you can't make any statements at all about "retina" qualities based solely on PPI, right? "Retina display" is based on an angular measurement, so you need PPI at a specified viewing distance. And the rMBP meets that at its typical viewing distance.

    (On an anecdotal note, I work with video as a profession, so am very sensitive to pixels, etc, and this screen is gorgeous, density-wise.)

    You mention all of those "far better" displays from 5+ years ago... Were they in laptops, or were they expensive desktop options? What manufacturer has continued to make them since then? In fact, most everyone except Apple has headed towards the consumerized, 16:9 1920x1080 (1080p) screen size, which is 15% shorter than Apple's displays. Contrary to popular opinion, Apple has been holding out for the more useful, professional aspect ratio and resolution, while its competitors have chased the checkbox of "Play Bluray DVDs at HD resolution".

    In terms of your actual comments, the rMBP's display is in the top two or three laptop screens for contrast and blacks, basically falling a bit short (top 6-8) in white because Apple just couldn't pump up the brightness without compromising battery life too much. Color accuracy has dropped a bit from older MBP's. Still, the combination of perceivable features is the best most of us have ever seen outside of a calibrated desktop setup.

    One thing to think about is that Apple's auto-switching between dedicated GPU and Intel graphics is a bit of a mystery. Some programs trigger the dedicated GPU and it's not clear why.

    For example, Eaglefiler (a terrific program) seems to trigger it, even though it's not a graphics heavyweight and even when it's hidden. With a program that you leave running all the time like that, it will drag down your battery life. The author is looking into this, but it's not clear what Apple API is the cause.

    In light of that, I'd highly recommend the gfxCardStatus, which monitors what programs trigger discrete graphics and which don't. It'll at least give you a clue that a program you wouldn't otherwise suspect may be shortening your battery life.

    okay, so we're looking at a screenshot. 15 FPS in the most uncluttered situations with D3. Can you even imagine the FPS in a normal situation during the game, even on normal difficulty?

    Hint: we're looking at FPS in the 1-3 range, maybe 4 if you're lucky.

    Apple can deliver great displays but if we don't have performance to match then the only main use is photoshop.

    If you have any brains you will bootcamp windows and game in there with usually 40% increase in FPS. No one games in OSX. Even OSX fanboys have better sense.

    I've said repeatedly in this thread that I get 20+ FPS in Normal Act III, with two or three dozen mobs onscreen. I've read at least one other report of 20+ FPS (perhaps this article mentions that in the text). And this is with settings mostly at max. Cut the res down to 1440x900 and drop a few settings to Medium and I think you could double the frame rate.

    So your speculation is wrong.
