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):

    Anand, on page 4 you categorize the rMBP as a consumer device: "At 220 pixels per inch it’s easily the highest density consumer notebook panel shipping today.", but back on page 2 you made a deal of of calling it a pro "appliance" and pointed out that it wasn't a consumer device.

    Other than that - this DPI improvement really needs to get moving. It's been so many years and we've essentially been standing still since LCDs took over and the monitor business became a race towards the bottom. IPS, high DPI and native support for it in software PLEASE. 120hz would be nice too.

    I don't understand why Apple doesn't take advantage of their lead in Thunderbolt. This machine screams for E-GPU with GTX 670!

    Probably because right now the user experience would be poor. See Anand's comments about sound and USB cutting out when high-bandwidth transfers are occurring. That would be catastrophic mid-game and would definitely lead me to return the hardware as unfit for purpose. Apple have had their slip-ups but they rarely release hardware that is unfit for purpose.

    Does Apple have some sort of exclusive deal (ie monopoly with an expiration date) on these displays, or can anybody (HP, Asus, Lenovo etc) use them if they want to?

    In recent years, Apple has been the King of the Supply Chain due to Tim Cook. He's now the CEO. I doubt that there will be many retina 15" screens available for Apple's competitors for a year or more.

    Even if Apple didn't lock up the supply chain, Apple's competitors have been running towards lower resolutions, or the entertainment-oriented 16:9 1920x1080 (aka 1080p), so it will take them a while to pivot towards higher-density displays even if they were growing on trees.

    Apple has been paying huge sums (in the Billions of Dollars!) to component manufacturers in advance to have them develop specific components such as this one, even paying for factories to be built for manufacturing exclusively for Apple for a certain time.

    It is also possible that Apple has licensed certain patents from various (other) manufacturers for their exclusive use which might preclude open-market sales of the same components even after the exclusive deal with Apple is up, because the display manufacturer may not be able to keep using these same patents.

    In short: The chances for PC manufacturers to get at them just by waiting for them to drop into the market eventually don't look too good.

    After all, none of the other Retina displays have appeared in other products yet. And the iPhone 4 is already two years old.

    So either the non-Apple-supplying component manufacturers or the PC builders will have to actually pay for their own development. And given their mostly dismal profit margins and relatively low volumes in the premium segment, I wouldn't hold my breath.

    Anand and Team,

    Excellent review again.

    When is the MacBook Air Mid 2012 review coming? I really want to see the battery life improvement, I can see that it almost tops out at 8Hours for light work load for 13" MBA.

    Cannot wait!!!

    Anand states: "[E]nough to make me actually want to use the Mac as a portable when at home rather than tethered to an external panel. The added portability of the chassis likely contributes to that fact though."

    I work with an external display at home, and given that there are none yet at this caliber, I'm wondering about doing away with the external display and working only with the rMBP. In the past I've always needed external displays for viewing more info, and I'm curious if this is no longer necessary.

    Has anyone tried doing away with an external display and just using the rMBP on a stand with a mouse and keyboard? Since the display includes more info than a cinema display, and given healthy eyesight, would this setup be as ergonomic and efficient?

    For several years, I've been using 17'' notebooks with 1920x1200 displays. That resolution had been more than enough for the 17'' form factor; having even such a resolution on a 15'' screen is going overboard, and doing it on an 11'' tablet is just plane bonkers. I don't see the individual pixels on my laptop's screen, and I'd wager neither would most other people unless they use magnifying lenses.

    I really don't get the point of wasting money on over-spec'ed hardware, and burning energy pushing all those invisible pixels.

    I'd rather have reasonable display resolutions matched to the actual physiological capabilities of the human eye, and spend the rest of the cost and power budgets on either weight reductions, or better battery life, or higher computing performance, or more powerful 3G/4G/Wi-Fi radios, etc.

    The marketing-hype idiocy of "retina displays" now appears to be driving the industry from one intolerable extreme (of crappy pannels with sup-par resolutions) right into the diametrically opposite insanity -- that of ridiculously overbuilt hardware.

    Why can't we just have cost-effective, performance-balanced, SANE designs anymore?

    Reminds me of comments when the 3rd gen iPad screen was introduced. You have a review which both subjectively (from an extremely experienced user) and objectively from tests shows this is the best display ever for a laptop. Yet people ignore all of that and say it's a waste... I think it would be a waste if it didn't actually... You know... Provide a visibly dramatic level of improvement. And its better to make a large jump bordering on "overkill" than to make tiny incremental steps with something like display resolution- fragmentation/etc being what it is,
