Our Verdict
Fourteen months after its release, the 15-inch Apple MacBook Pro with Retina display (Mid-2012) remains the finest notebook computer money can buy. A few competitors have stepped up with Retina-class displays, examples being the Google Chromebook Pixel, Toshiba Kirabook, Asus Zenbook Infinity and Samsung Ativ Book 9 Plus. None are serious competition – the Google laptop has limited specifications and its Chrome OS is arguably just spyware made manifest. The Windows laptops are saddled with Microsoft’s unpopular Windows 8 software which besides all its usability issues is not yet suited to high-resolution displays. None can match the build and performance of the Apple Retina-screen MacBook Pro. But for a prospective buyer today, we would advise waiting until this autumn’s possible refresh, which is likely to underscore the design’s lead, thanks to an even more efficient Haswell processor that is likely to extend battery life to beyond 10 hours, as well as improve graphics fluidity and uprate storage performance further with PCIe-connected solid-state storage. The final ace up a new model’s is likely to be much improved Wi-Fi performance thanks to the adoption of the 802.11ac wireless standard.
The new Apple MacBook Pro with Retina display (Late 2013) is almost upon us. But before the launch of the 2013 version of the Retina MacBook Pro, it’s high time to take a closer look at the world’s finest notebook computer – the 15-inch Apple MacBook Pro with Retina display (Mid-2012).
We put the first Apple MacBook Pro with 15-inch Retina display back on the lab testbench. Apple UK loaned us an original model with 2.6 GHz Intel Core i7 processor, 8 GB of memory, 512 MB storage and nVidia GTX 650M graphics with 1 GB of video memory. Note however that models currently on sale include either a 2.4 or 2.7 GHz processor, after Intel’s running processor upgrade early in 2013. The latter 2.7 GHz model now also receives 16 GB of memory as standard, while our sample had 8 GB.
Update: Apple unveiled new MacBook Pro models at its 9 March 2015 press event. For more details, take a look at our New 13-inch Retina MacBook Pro (early 2015) preview.
Apple MacBook Pro with Retina display: Unibody goes Retina
October, five years ago, saw the introduction of the Unibody design of Apple MacBook Pro. Today’s Apple MacBook Pro with Retina display is a distillation of that one-piece shell laptop, brought up to date with the third-generation of Intel Core i7 processor.

At heart then is a powerful quad-core Intel processor that runs efficiently enough to provide useful runtime from battery power. The Retina MacBook also marked the first MacBook Pro with solid-state storage as standard. It makes perfect sense – apart from price, there’s no downside to switching to a solid-state drive.
Front and centre though, the real breakthrough with the MacBook Pro with Retina display is of course the incredible display. Like the iPhone and iPad before it which pioneered ultra-high density IPS-technology screens in mobile computing, the Retina MacBook’s screen has pixels so tightly packed together, you cannot discern them at normal viewing distances. (See What is a Retina display, and are they worth the money?)
While the iPhone has 326 pixels per inch (ppi), the 15-inch Apple MacBook Pro with Retina display has a lower pixel density of 220 ppi – still amply sufficient to give the required effect when viewed from a comfortable distance of around 60 cm.
The display weaves its magic by rendering as if it had the same 1440 x 900 pixels as every previous 15-inch MacBook Pro; but using 2880 x 1800 pixels in a quad-resolution system also known as HiDPI mode. This places considerably more strain on the graphics processor which must render four times as many pixels – a trickier task when displaying motion video or gaming action. But Apple’s implementation with either of its graphics controllers (just) about manages it.
The Retina effect on a laptop is stunning. Image quality is breathtaking, consigning every laptop screen before it into near obsolescence. Incredibly fine details can be found in images, and combined with the wider gamut and higher-contrast screen, it reproduces beautifully rich colours and textures like no other notebook computer before it.
Look even closely at the elements of the OS X interface, and you won’t see any jagged edges. Beyond the beauty of photographs and graphics, the Retina MacBook is a real boon to readers, to editors, to anyone that reads printed words from the screen. Typography is rendered exactly as it was designed, without the need for fuzzy anti-aliasing to give the semblance of rounded script edges.
We evaluated the screen using a Datacolor Spyder4Elite colorimeter to find some numbers to back up some of our hyperbole. The device cannot quantify the HiDPI mode effect, but it did show that the display was capable of showing 98 percent of the sRGB gamut, and 76 percent of Adobe RGB. Those figures are good, but not uniquely outstanding.
Our non-Retina MacBook Pro (Mid-2012), meanwhile, takes a twisted-nematic (TN) display. A very good example of the technology, it measured 92 and 68 percent respectively in the same gamut test.
Contrast ratio in the checkboard test of the standard MacBook Pro came in with 520:1 contrast ratio. The Retina MacBook Pro was recorded at 720:1 at its maximum measured brightness of 300 cd/m2. That’s a high maximum brightness too – impressive looking but too high for normal use. The only time you may need such a level is when working outside in strong daylight.
Colour accuracy is impressive too. We ran a Delta E test, and looked for deviation from absolute colour fidelity with a range of 48 spot-tone tests. The Retina MacBook Pro averaged just 1.35 Delta E. Our TN-screen MacBook Pro measured a little higher, but still good, 2.40 Delta E.
The Retina display has a shiny glass front, normal the enemy of easy viewing despite the illusion of saturated colours and high contrast. Yet this screen is manufactured by a special process that bonds the TFT panel to the glass to reduce reflection and refraction. Additionally, like older models of gloss-screen MacBook Air, there is an optical reflection-reducing coating to improve viewability in normal daylight conditions. The result, like that now matched by the latest iMac displays, is the best gloss screen we’ve seen.
Apple MacBook Pro with Retina display: Flash storage
An SSD is shockproof and won’t suffer disk crashes from the movement of the laptop. It’s lighter in weight, shaving precious grams from the total. Power consumption is lower – when mitigated by the amount of data it can push in a given time anyway. But the golden metric is of course its incredible speed.
The Apple MacBook Pro with Retina display comes as standard with 256 GB of flash storage. Our sample had 512 GB capacity, taking Apple’s non-standard type of flash storage that resembles the pared-down mSATA card. It’s still essentially Serial ATA Revision 3.0, but the connector is proprietary to Apple.
And it is fast. Like most computer brands, Apple will buy in components from more than one supplier, and we understand both Toshiba and Samsung SSDs are in use by today’s Retina MacBook Pro.
Our sample had Samsung flash NAND inside. We tested its performance in OS X, and saw sequential read speeds up to 480 MB/s, while sequential writes averaged 402 MB/s.
At the small file level, the Intech QuickBench could unfortunately only offer single-threaded testing, so we couldn’t assess the SSD in the best way possible – input/output operations per second, or IOPS – but random reads averaged from 4 kB to 1024 kB amounted to an average of 131 MB/s, while random writes here averaged 152 MB/s.
This latter random read/write test is crucial in assessing how fast a computer feels in normal daily use. And those 131 and 152 MB/s random-access numbers give an excellent indication of real-world speed that will be terrifically fast when launching applications and opening and saving files.
But watch out for the 2013 MacBook Pro Retina, which will almost certainly feature the PCIe interface spearheaded by the 2013 MacBook Air. By removing the classic SATA interface entirely, solid-state storage performance will sky rocket beyond the current circa-550 MB/s barrier.
Apple MacBook Pro with Retina display: Processor
An Ivy Bridge-generation processor is a very fast asset in any computer. And with its third iteration of Core Series technology, Intel again reduced power consumption and heat output while still increasing measured performance, rated against the previous year’s Sandy Bridge series.
The 2.6 GHz Intel Core i7-3720QM here has four discrete cores, but arranged into what Intel calls Hyper-threading technology. This allows each core to manage two independent threads separately, effectively letting the OS X system ‘see’ eight processor cores. Additionally, one of those cores will overclock automatically under demand to 3.6 GHz, a short-term Turbo boost to plough through tasks more quickly.
We used the Geekbench 2 test, which uses cryptography routines and similarly sophisticated number mangling to push a modern processor to the maximum. This benchmark’s baseline result of 1000 points was garnered by a (now) rather elderly reference machine – an Apple Power Mac G5 with a single 1.6 GHz IBM PowerPC processor.
Nevertheless, the 15-inch Apple MacBook Pro with Retina display (Mid-2012), powered by the original top off-the-shelf option of 2.6 GHz processor, scored an average of 13,088 points in Geekbench 2.
So for context, the 15-inch Apple MacBook Pro with Retina display here has the processing clout of a baker’s dozen of Apple’s professional desktop workstations from a decade ago.
A revised Geekbench, version 3, has a useful extra trick. Like the venerable Cinebench test, it will additionally show the best speed when only a single core is put into action. That’s handy to demonstrate available performance in single-threaded applications.
In Geekbench 3, the Retina MacBook Pro averaged a result of 12,670 points with all cores running, and 3254 points with a single thread. So rather than a simple 8:1 ratio in speed, we can get a clue to the effect of Turbo-boosting on one core with closer to a 4:1 difference.
Apple MacBook Pro with Retina display: Graphics
Apple’s top-of-the-line 15-inch MacBook Pro notebooks include two graphics processors – a relatively low-power graphics controller built into the main Intel processor for everyday tasks, and a dedicated nVidia GeForce GTX graphics processor which automatically takes over for more demanding tasks. Our sample had an nVidia GsaeForce GTX 650M with 1 GB of GDDR5 video memory.
We gauged graphics performance with several gaming benchmark tests. In Batman: Arkham City and with quality set to 1280 x 800 pixels and Medium detail, the Retina MacBook Pro averaged 50 fps; the result of moving up to ‘screen native’ 1440 x 900 pixels was effectively the same at 51 fps.
Turning to the Unigine engine test, the Retina MacBook could replay the Heaven benchmark test at 35 fps at 1280 x 800 pixels; and 29 fps at 1440 x 900; both with default Medium detail selected. With Unigine’s newer Valley benchmark, we saw figures of 37 and 32 fps respectively.
With any intensive graphics or gaming routine, we saw internal temperatures rise, enough to make the fans audible but as noted below not disturbingly so thanks to a clever cooling regime.
Graphics horsepower was good overall, good for most games but not outstanding by the standards of professional mobile workstations. Connect an external display in addition to the built-in screen to view these games, and framerates collapse to the high teens in frames per second.
And even the OS X interface could stutter jsut perceptibly in something as mundane as scrolling a webpage in Safari. We’re hoping that the next generation of MacBook Pro with Retina display will benefit from a speedbump in graphics performance to restore completely a fluid graphical interface. Haswell’s improved integrated graphics bode well for a small lift here too.
Apple MacBook Pro with Retina display: Build quality and design
At just 18 mm thick, the Retina MacBook Pro 15in is disarmingly slim for such a powerful laptop computer. Then again, making a thin notebook is not so difficult given the right choice of components – integrated and non-removable lithium polymer battery, mSATA-style storage, and the removal of an optical drive.
Harder, much harder, it is to balance performance and a slim chassis with heat and noise. Inside the MacBook Pro with Retina display are two innovative cooling fans. Their assymmetrically spaced blades reduce audible resonance, so when the fans do ramp up from their idle 2000 rpm to higher speeds, up to 5000 rpm when required, the result is far more peaceful than any other laptop on the market today. Their combined sound is more like the even white noise of a detuned radio or distant river, rather than the whining drill of a traditional cooling fan.
The low-profile keyboard we found to be even more comfortable for fast and consistent typing than the very similar design of out Mid-2012 Unibody MacBook Pro. Backlighting has improved though, so there’s less light bleed from around the keys than in the usual Unibody model, and key profile is slightly lower.
The large glass trackpad is now being emulated in the Windows world, we’ve noticed, but only perhaps in size: having experienced the best that Microsoft’s hardware partners can muster in touch control, we’d say the MacBook range has the finest trackpads you’ll find in terms of sensitivity, precision and sheer satin slickness.
Controversially, besides the dual-layer DVD±RW optical drive Apple removed several familiar ports and connectors from the 15-inch Apple MacBook Pro with Retina display. Gone is gigabit ethernet, FireWire 800 too, replaced by two separate Thunderbolt ports. You can find Thunderbolt adaptors at £25 each that will restore the network and FireWire connectors, even if you lose the convenience of always having them built-in and ready without having to rummage for errant dongles.
On the left are the two Thunderbolt ports, plus MagSafe 2 magnetic power connector, USB 3.0 and a headset jack with Toslink optical audio output. On the right is another USB 3.0 port, SDXC card slot and HDMI port.
It’s worth noting that the latter video output is limited to an older version of HDMI, v1.2 or earlier it seems, since no resolution greater than 1920 x 1200 was available from this port when we plugged into a Dell professional monitor with 2560 x 1600-pixel display and HDMI 1.3a ports. That’s a shame, as it means you must use a valuable Thunderbolt port to connect to such ultra-high resolution monitors. And as we move into the future of HiDPI retina-class viewing, we will need those higher resolution displays all the more.
Apple MacBook Pro with Retina display: Battery life
Considering the complement of quad-core processor and retina-class IPS display, runtime away from the mains remains very good. The large reserves of power available from three internal power packs certainly helps bolster battery life – there’s nearly 100 Wh of lithium-polymer energy cells distributed inside.
As a guide to real-world battery life, we presented the Retina MacBook Pro with two similar scenarios. First, playing an MPEG-4 video file – a Blu-ray rip of Avatar – on a loop with QuickTime Player; and then the same film played with VideoLAN Client (VLC). In both cases the screen was calibrated to 120 cd/m2 brightness and set not to dim.
The difference between software players goes some way to highlight the difference in potential runtime available, depending which of the two available graphics processors is currently in use.
QuickTime is well-equipped to use hardward-accelerated video playback, passing the strain of video decode from CPU to GPU, enabling much more efficient (and often smoother and higher quality) playback. And following Apple’s release of the VDADecoder API three years ago, we believed VLC was hardware-accelerated too by the graphics processor, since we’d noticed that opening VLC would always cause the MacBook to switch from Intel to nVidia graphics.
Playing the H.264 file with QuickTime 10.2 and the video decoded by Intel HD Graphics 4000, we saw CPU load at just 6.5 percent. Played on a loop, the MacBook Pro with Retina display lasted 7 hours and 5 minutes from a full charge.
Playing the same file with VLC 2.0.8 and the nVidia GTX 650M automatically powered up. The MacBook Pro with Retina display survived for 4 hours 43 minutes under the same conditions.
However, we now believe the latter scenario was actually still using CPU decode, since hardware acceleration is not due in VLC until v2.1.0, due for release soon. We compared VLC 2.0.8 and VLC 2.1.0-pre2, and saw CPU usage fall from around 20-25 percent, to a steady 12.5 percent.
This suggests that in our second battery use scenario, we were experiencing the worst of both worlds – discrete graphics card powered up and full CPU video decoding.
