I’m still not entirely sure when it actually happened, but at some point over the last couple of years the crossover between tablets and laptops stopped being an idea and became a real thing. Perhaps it was Microsoft’s Surface Pro 3, which came out as an x86 Core architecture tablet that was finally thin enough to no longer be an awkward laptop without an attached keyboard. Or maybe it was the more recent release of Intel’s Core M family of CPUs, which brought the Core architecture to a sub-5W design for the first time while making the overall SoC thinner than ever before.

But either way you cut it, the line between tablets and laptops is blurrier than ever before. The performance of tablets is continuing to improve through faster CPUs and unexpectedly powerful GPUs, all the while laptops and high-performance x86 tablets are getting thinner, lighter, and lower power. There are still some important differences between the devices, and this is a consequence of both current technological limitations as well as design differences, but clearly the point where traditional tablets end and traditional laptops end is no longer a well-defined one.

This brings us to today’s review and today’s launch of Apple’s latest ultra-thin laptop, the simply named MacBook. Though Apple’s device is distinctly a laptop in terms of form factor and design, you’d none the less be excused for mistaking it for a large form factor tablet if you took a look at its overall size and internal configuration, both of which are far closer to a tablet than a laptop. Apple may not be doing any kind of wild 2-in-1 transforming design, or even pushing the concept of a touchscreen OS X device, but they have clearly tapped their immense experience with tablets in putting together the new MacBook.

The 2015 MacBook is an interesting take on building a Mac, one whose outward appearance hides just how much Apple has done under the hood to make it possible. Ostensibly the MacBook is an ultra-thin, ultra-light laptop, pushing beyond even the standards for Ultrabooks as first established by the MacBook Air. Retaining many of the qualities of Apple’s MacBook Air and Retina MacBook Pro lines, the MacBook delivers the Mac laptop experience in a device that is at its largest point just 1.31cm thick, and whose overall footprint is even smaller than the 11” MacBook Air, despite the fact that it includes a larger 12” screen.

From an end-user standpoint then the focus on the MacBook is going to be on its size, especially its thinness. It’s how Apple is choosing to promote it and it’s by far the laptop’s most distinctive attribute. At the same time however is the story of how Apple got to this point, and what trade-offs and sacrifices they had to make to get a laptop into this form factor. The laws of physics enforce a pretty clear trade-off between size and performance, so in creating the MacBook Apple has not only created a new size category of Macs, but a new performance category as well. It’s smaller than even the MacBook Air, but it also follows a different performance curve, and ultimately is targeted at a somewhat different user base than the now-traditional ultrabook.

We’ll get back to the MacBook’s design in a bit, but first let’s talk about specifications and pricing. With the MacBook Air having transitioned from Apple’s ultra-premium ultra-portable laptop to their entry-level ultra-portable laptop over the last few years – killing the original MacBook in the process – there has been a lot of demand for a premium MacBook Air, particularly one implementing a Retina display. In releasing the new MacBook Apple looks to be addressing at least some of those demands by finally putting together an ultra-portable laptop with just such a Retina display, but in the process they have also re-established the MacBook as a line of premium laptops, along of course with all the differences that come from making such a thin and light laptop.

This makes the new MacBook more expensive than the larger MacBook Airs, with the entry level MacBook starting at $1299, versus $899 for the 11” MacBook Air. What that $1299 gets you is access to the first of Apple’s laptops based on Intel’s Core M processor, which in turn is a big part of what has allowed Apple to make such a little laptop.

With Core M rated for a TDP of just 4.5W and only being 1.04mm thick, Intel geared their smallest Core processor towards larger format tablets and fanless laptops, with Apple tapping Core M specifically for the latter. Core M in turn is a reality through a combination of Intel’s new 14nm fabrication process and some very tight power and thermal controls to ensure that the processor doesn’t exceed the tolerances of the laptop it’s built around. Compared to Intel’s mainline Core i family, Core M is a very fast processor in short bursts but over longer period of times has to live within the confines of such a small device, which we’ll explore in greater depth in our look at the MacBook’s performance.

Core M/Broadwell-Y (left) vs Broadwell-U (center) vs Haswell-U (right)

Overall Apple is offering 3 different versions of the Core M within the MacBook lineup. The $1299 base configuration utilizes a 1.1GHz Core M-5Y31, while the $1599 utilizes what we believe to be a 1.2GHz 5Y51. Finally, both configurations offer an optional upgrade to a faster processor, a 1.3GHz version of what’s likely the 5Y71, which is the fastest of Intel’s current Core M lineup. However to put a twist on things Apple has gone and clocked these processors slightly differently than Intel’s original specifications; all 3 MacBooks have a base clock higher than Intel’s specs, and in the case of the faster two these don’t even match Intel’s faster “cTDP Up” configurations. As a result the Core M processors in the new MacBook are somewhat unorthodox compared to the regular processors - and perhaps slightly more power hungry - though there’s nothing here that other OEMs couldn’t do as well.

Ideally Core M will spend very little time at its base clockspeeds, and will instead be turboing up to 2.4GHz, 2.6GHz, or 2.9GHz respectively. This vast divide between the base and turbo clocks reflects the performance-bursty nature of the Core M design, but it is also why the base clockspeeds that Apple advertises can be deceptively low. In light workloads where Core M can quickly reach its top speeds to complete a task, a 2.4GHz+ Core architecture processor is nothing short of zippy.  However in sustained workloads these base clockspeeds become much more relevant, as Core M has to pull back to lower clockspeeds to keep heat and power consumption under control.

In any case, Apple has paired their first Core M laptop with some other very solid hardware, and thankfully in configurations much more befitting of a premium laptop than the MacBook Air’s anemic base specifications. No model of the MacBook comes with less than a 256GB PCIe-attached SSD, a welcome development for a company that has traditionally skimped on SSD capacities. Similarly the one (and only) RAM configuration is 8GB of LPDDR3, which all-told is not a massive amount, but is more than plenty for the kind of device Apple is building towards.

Compared to the 128GB SSD and 4GB of RAM in the base MacBook Airs, this is the first ultra-portable Mac in a while where I can say even the base model feels properly equipped. At the very least users shouldn’t be struggling with RAM or SSD capacity for some time. Meanwhile given the fact that the equivalent upgrade of an 11” MacBook air would be $300 – bringing the total price to $1199 – this means that while the MacBook is still more expensive than a MacBook Air, the difference isn’t nearly as wide as it would first seem.

Rounding out the MacBook’s build are a few firsts for Apple. The MacBook’s 12” 2304x1440 Retina IPS display is the first Retina IPS display in an Apple ultra-portable, and quite the sight to behold. Meanwhile the MacBook is also the first Mac to come equipped with the new USB Type-C port, similarly small and fully reversible. Both of these help to cement the MacBook’s place as a cutting-edge Mac, similar to the Retina MacBook Pro’s position in 2012 when it was launched.

    "I’m going to start where I left off in our introduction, which was the concept of the laptop/tablet crossover. The idea of laptops and tablets crossing over is no longer merely an idea, but now it is reality"

    Yea. Back here, we call those "Netbooks". But "crossover" sounds cooler.

    You don't know what a netbook is. They were cheap devices with low quality screens and poor build quality. Try reading the review you are commenting on. Reply

    OK, so it's a better quality netbook. Got it :P Reply

    Sorta like how a laptop is a higher quality netbook.

    Or, how a computer is a higher-quality calculator.

    Maybe in 2012 laptop is higher quality netbook. I am starting to feel that Anandtech is getting too 'careful' with the OEMs. M9 is bad, call it that. this Macbook fits squarely in the netbook term from functionality standpoint, despite the price premium for the fit and finish. No need to redefine a new 'crossover' term just to keep Apple marketing managers happy.

    Right now, chromebook and other ultraportables (such as this one) with the relatively slow core M are the de-facto sucessor to netbook. Single usb port also a netbook typical compromise. It not convertible nor it has a touchscreen, so.. NETBOOK.

    Tech evolves, therefore performance expectation should evolve with it. the core M is barely faster than a 2012 intel i3-3217U on geekbench. It is the lowest performance tier of Intel big core family.

    Anandtech used to be unbiased, I think they finally started the slow descent towards 'marketing for OEM'. I understand where this is coming from, and I am willing to pay for anandtech subscription if that what it takes to restore the one place a techie can get an unbiased, deep dive into new techs.

    Purch should differentiate Tom's & Anand by using Tom's for their mainstream, 'marketing compatible portal' while turning Anand into a subscription based portal, with reviews selection based on customer votes, each one completely unbiased, purely technical, pull-no-punches style.

    Something like the transformer book is a modern day netbook: atom processor, $300 price, questionable build quality --- all the traits of a netbook. Reply

    Yet another fine addition to the long list of "Terrible Products Apple Makes to Gouge Money out of People".

    The new MacBook is a testament to Apple's collapsing technical acumen. They eliminate all ports except for one outdated USB port? This craven stupidity should send the last adherents running. But running to what? Windows isn't even a viable option anymore, since it now is the most widespread commercial NSA gathering tool available, closely followed by Android, iOS and OS X.

    It's a sad day for people who need real computers. Jony Ive is a pompous, clueless hack who should be fired for introducing crippling regressions like this one.

    Look at this POS: One USB port, which will require an adapter to do anything. So if you're going to require an adapter anyway, why not make that one port a modern one: Thunderbolt. Thunderbolt can carry USB, video, Ethernet, external storage... ALL AT ONCE. And it can be daisy-chained, which is hugely important when the computer has ONLY ONE PORT. So WTF is Apple doing making its sole port USB?

    And again, are you kidding me? One tiny USB connector? Now every sorry user of this pos has to find a thunderbolt to USB C, a USB C to USB to HDMI, a USB to USB 3.0 period, a USB C to USB connector for apple’s time machine and also manage to don't short circuit all that with the AC/DC to USB C connectors, seriously ? Worth 200$ new pile of hairy connectors for the brand new gold macbook air, and that is called a revolution nowadays? No ********** way, the Dell XPS 13 is way superior, period.

    By the way, they're perpetrating USB Type C connectors. Thunderbolt is a much-needed step to a modern I/O standard. USB is an outdated, abused standard that was designed for keyboards, mice, and modems. It's not suitable for external storage, video, or anything else requiring bulk data transfer with minimal CPU overhead. USB C is a regression, a major step BACKWARD.

    $1599.99----Less than $550.00 worth of hardware = ~$1000 premium to use OS X instead of windows. (Honestly the most expensive component of this computer is probably the screen.)
    Anyone with real work to do will not even be able to buy this thing. My friend’s last Air was neat in that it was small and lasted all day, but it was so under-powered, it was frustrating. I can only imagine how limited this machine will be.

    Who cares about price, weight and size, when this product is crippled by a hopelessly defective design? You can't hook up a power adapter and external storage at the same time. You can't hook up an external display and external storage. Hell, you can't even plug in a thumb drive!

    This product is the most asinine piece of shit Apple has produced, and that includes the (thankfully) short-lived Shuffle that could only be controlled by a gimped Morse code.

    $700 less gets you the new Dell XPS 13 which will eat the Mac's lunch.

    If you need to do a lot of processor intensive work, than you would not even go near this thing. It would be useless to you. If you need to crunch spreadsheets or are heavy in corporate analysis, this computer would also be useless to you.

    This is the kind of computer that Apple sells a lot of. This computer is largely useless for anything other than email and facebook. It cannot store many files, it cannot process much information, and it has one external port. There is nothing wrong with using this computer for casual tasks, but it is CERTAINLY not a productivity machine.

    It is what it is. A status symbol/statement. Or some other statement. A statement that you just bought a $400 netbook with a $900 case so you can show off in front of your hipster friends.

    I hate to stick to Apple only facts here, but Apple said that the Air is 24% thicker than this new Macbook. That does NOT mean that the new Macbook is 24% thinner than the Air, it means that it is ~20% thinner than the Air. They clearly phrased it that way to make it sound more impressive and hence dupe the consumer, aka stupid isheep.

    So, it's an iPad plus with a keyboard and an over expensive dongle so you can do everything a Dell can do, at twice the price while looking posh.
    And here I thought technology was about function over form. I get it, functional art; art I can do things my phone does, but in a space that anyone can see me doing it, stylishly. Crippled and non standard in-house branded "business" software does great, can't do anything really artistic on it except maybe GarageBand or stock filter photo edits to my innumerable selfies, but it's got that partially eaten fruit on the back that screams "money I'm too stupid to keep or invest wisely."

    Take my money!
    I wouldn't hold my breath.

    This is apple's marketing strategy: mind-numbing markup on dirt-cheap, mediocre laptops. They throw together a cheap little laptop, pretty it up with silver or gold paint, and ride the wave of ignorance, outrageous markup, and marketing that they've been using as a business model for many, many years now. The only thing Apple has ever made that's less worthless than all the other crap their conspirators like Hon Hai Precision Industry Co., Ltd excrete all day and night by taking advantage of child labour are iOS and OS X which, besides being notoriously crippled and constrained walled gardens, aren’t even worth the hassle unless you also dumped thousands of dollars into other apple products.

    Many apple owners I’ve encountered never stop trying to belittle and demean others because they don’t have a Macbook or an iPhone and then try to act like their overpriced apple products are overall better when they are certainly not, by any standard.

    Luxury cars, while still worthless crash grabs, usually offer some quality and features that are actually somewhat superior to cheaper competing brands and models.
    Macbooks such as this start already expensive as hell with little performance to warrant such outrageous costs. Apple isn’t the luxury car of anything. It’s the luxury car DESIGN with a 4-cylinder under the hood and a tape-deck in the sound system, all with the price tag of "luxury". They sell laptops made cheap in china, using child labour and the same hardware you can find in SO many other laptops, slap their OS on it, put it in a thin case, and then markup the price by 300% to 600%. These are the facts. This laptop in question is nowhere NEAR worth that kind of money. I mean, laptops in general are overpriced, but apple has made their entire business model out of extreme markups backed by clever marketing with little actual technological superiority of any kind. Every single apple product on the market can be outperformed in every way by comparable products. Apple computers can be outperformed by computers that are FAR FAR cheaper while relying on older tech. The only thing that apple has that nobody else does is OSX and iOS, their operating systems. These are mediocre operating systems, but they are literally designed to be limited on anything it determines to be "non-apple hardware". Other operating systems can be installed on just about any computer you can slap together, whereas OSX is specifically and deliberately designed to be non-functional on ANYTHING that isn’t made by apple. It’s nothing but a cash-grab.

    Apple is indeed playing run-of-the-mill capitalism, they try to capitalize on the ignorance of the average consumer with marketing campaigns designed to make you assume you're getting your money's worth.

    There are millions of consumers who are on the fence, who are actually interested in buying something that's worth the money they spend. Those people deserve factual information and do not deserve to be exploited for their ignorance on the topic. So excuse me if I have a problem with it. College students especially, who don’t have a lot to spend in the first place, are being taken advantage of in every area of their life. Buying a computer should be one less area of exploitation. This is why I have a problem with apple and with many other companies and services that attempt to capitalize on ignorance.

    Years down the road when the batteries in this model are dead and you have to keep it plugged in just to use then you'll have no way to plug in a flash drive or an external hard drive. I don't care how sexy it looks: sometimes and more often than not less means a serious lack of functionality.

    We can only hope that consumers send this piece of diabolic garbage to oblivion, as they did the idiotic iPod Shuffle that could only be controlled with Morse code over a proprietary headphone wire.

    You literally just typed a small novel spewing a bunch of claims without citing anything to support your arguments, or outright fabricating stuff. It's the absolute definition of a poorly written, complete waste of time. Please take your rants elsewhere, Anandtech readers, last I checked, enjoy discussing tech, not spouting conspiracy theories and raving like lunatics. Reply

    People have the right to have an *informed* opinion. The long post above is unfortunately based mostly on ignorance.
