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):

    Great review as usual, but I would really like to know how Anand was able to check if Speedstep and Turboboost worked. In the last Macbook review (2011), he used MSR Tools, but I could not get these to work on Lion on my June 2012 MBP 13. He remains very vague about how, although he does confirm this works as expected on the MBP 15r .
    This isn't my experience. I tried using Intel's MacCPUID in Lion, and a few other tools, and it looks like the CPU is locked at nominal speed (2.9GHz in my case), so neither speedstep nor Turboboost seem to work in Lion. They work as intended in Win7/Bootcamp, going down to 1GHz to save battery or up to 3.6GHz when only one core needs more power.
    So here are my questions:
    1) Anand please could you tell us which tools you have used?
    2) Has anyone tested this on the new macs (June 2012), using which tools, and what is the result?
    Speedstep definitely worked in Snow Leopard on my MBP 13 2011, so it must be a limitation in Lion.

    Even the iPhone 4 is physically easier to maintain/upgrade than this thing.

    Check http://www.ifixit.com

    The worst maintainable piece of hardware they have ever looked at!!

    You didn't address whether pixel doubling is supported for games. IE rendering each pixel as 4 screen pixels. That's very different from upscaling, because with pixel doubling there's no blurring. Reply

    I've given up waiting for Apple to refresh the iMac, and am thinking of buying the Macbook Pro Retina instead. My only concern is that Apple should have equipped this laptop with a more powerful graphics card, given it is driving such a high res screen.

    I will be using it for Photoshop and HD video editing along with some gaming.

    Any help appreciated.

    So, I've done my best to read (skim) through all 46 pages of comments for this post, and have been reading other threads on more-or-less the same topic, so forgive me if I've missed something.

    I own a base model rMBP w/ 16mb ram (for safety), and am really quite unimpressed by openGL performance in games that were fluid (30-60fps ANYway) on my old Mac Pro 2006 w/ an ATI Radeon 5770 HD graphics card (I guess it helps, too, that the Mac Pro GPU is sitting in an x16 PCIe lane, not an x8, as with the rMBP). The Mountain Lion upgrade has been some improvement.

    When I first read Anandtech's article, I sort of thought, why not shut the lid on my MacBook Pro Retina, and plug in my old Apple Cinema display when I want to play games (I plan on using my desktop display when I'm at home for most stuff anyway). Then, the discreet NVIDIA GeForce GT 650M wouldn't be overworked by having to render all those extra pixels, right? Wrong. Gauging from the tests I've done, anyway, I'm getting the same choked performance on my relatively low-res external display (with the rMBP lid shut) as I do when I play those games on the rMBP screen (either at native OR scaled resolutions).

    So my question becomes, isn't this a software issue? Shouldn't the Apple/NVIDIA engineers be able to re-route ALL of that sexy mobile GPU processing power to a single, lower-res external display, and save us gamers the hassle of trading in our rMBPs for regular 2012 MBPs?

    This computer upgrade is really a no-brainer for me, otherwise. With the Thunderbolt ports, and the built in HDMI, I've been easily able to retire my old Mac Pro, and still keep my various displays (HDTV, etc.), and extensive array of USB/Firewire accessories fully operational. It just blows my mind that I get better gaming performance from my creaky old 2006 Mac Pro.

    Thanks for reading my contribution to this thread. Does my thought hold ANY water? I sure as heck don't want to give up this beautiful-looking piece of hardware if I don't have to...

    Cheers,

    Here's what I don't get and haven't seen answered anywhere. If there are performance issues at 1800p, can they be alleviated by downscaling (eg to 1080p)? Reply

    That sounds like great. good effort. Also have seen nice article on http://techinlead.com/apple-introducing-macbook-pr... Reply

    maybe i'm wrong, but i always thought that OEM means "Original Equipment Manufacturer", a company that makes equipement that is sold by others under their own name.

    Toshiba making hard drives for Apple makes it an OEM, just as Intel, Samsung and others

    but, Apple IS NOT AN OEM, and there is no such thing as a PC OEM !!
    a PC OEM would be a company that supplies parts to build a PC, not the PC maker itself.

    did i miss something here ?

    Now that Mountain Lion has been out for a bit and several programs have been "retinized" are you planning on updating your review or crafting a mini-review that addresses changes, improvements and new caveats? I, for one, would love to hear about scrolling performance and resolution impact to common software (the OS and iWorks, FinalCut, etc), such as setting the display to "more space" (1920) and clocking the Safari FB news feed, and so on...
