External Differences

The 13-Inch and 15-Inch Retina Display MacBook Pro versions share the same sealed wafter thin-like glass and aluminum designs. Compared to the MacBook Air, that are tapered from their back all the way to the front, the Retina Display MacBook Pro lines are thick. For instance, the 13-Inch series are 0.75-Inch thick, 12.35-Inch wide, and 8.62-Inch deep. The unit weighs more because it is 3.5 pounds, or 1.62 kg., while the 15-Inch units are 0.71-Inch thick, 14.13-Inch wide, and 9.73-Inch deep and it weighs more than the previous with 4.5 pounds or 2.02 kg.


These lines use the high-resolution LED-backlit widescreen “Retina” display. The difference though is that you will not see the brand printed on its label or display bezel. The “MacBook Pro” is only found on the bottom. As expected, the display size and resolutions are unique for each model. The 13-Inch versions include a 13.3” widescreen 2880×1800 (220 ppi) display. As per default settings, the 13-Inch and 15-Inch Retinal Display MacBook Pro models operate a “pixel doubled” graphics at 1280×800 and 1440×900. This is four times better than the traditional display found on old computers that most users have been accustomed for.


Furthermore, both of these models use a full-size “chiclet-style” backlit keyboard, and a glass “no button” trackpad that supports “inertial scrolling.” On top of this, the units have dual microphones, integrated stereo speakers, and as well as a 720p FaceTime HD webcam. It has to be noted that neither of them has a built-in optical drive. If you are in need of this, you can buy an external drive but only for an additional cost.


Connectivity Differences

The 13-Inch and 15-Inch Retina Display MacBook Pro models share the same connectivity options. They have 3-stream 802.11 a/b/g/n, two USB 3.0 ports, Bluetooth 4.0, an HDMI port, two “Thunderbolt” ports, an SDXC card slot, an audio out port, and also a “MagSafe 2” power connector port.


Neither of the two also has a Gigabit Ethernet or Firewire “800” but Apple has an alternative to this with their Thunderbolt-to-Gigabit Ethernet and Thunderbolt-to-Firewire 800 adapters. You can get this for an additional cost.


Identification Differences

When we wrote this Q&A, the 13-Inch “Late 2012” Retina Display MacBook Pro versions are identified through their unique Model Number, A1425, while the 15-Inch “Mid 2012” Retina Display MacBook Pro versions are externally known as A1398.


As for their software, the 13-Inch models are easily identified with their shared Model Identifier MacBookPro10,2, while the 15-Inch versions are known as the MacBookPro10,1.


But, since the subsequent lines have the same model numbers and model identifiers, it would be best to use the EMC Numbers instead for they are effective in long-term identification. For example, the 13-inch models have the 2557 EMC Number, while the 15-Inch versions are labeled as 2512. To make this more convenient, we have painstakingly documented all the details you might need to learn more about the model you own.


Lastly, we have a lookup feature that can uniquely identify the Retina Display MacBook Pro you own with only the help of its serial numbers.


Internal Differences

In terms of internal settings, these systems share some attributes. They both utilize Intel’s “Ivy Bridge” architecture, 1600 MHz DDR3L SDRAM that is attached permanently in a place. Furthermore, the SSD modules are also upgradeable with their batteries glued too. Besides these similarities, their differences are worth taking too.


Neither of the models allows internal flash storage upgrade after the initial purchase, however, it can be modified after. Moreover, the 15-Inch model features an SSD with a removable module, while the 13-Inch comes as a pleasant surprise for it welcomes more options for upgrade. The 13-Inch line employs the same removable module like the default of the 15-Inch; but, the system has a “drive caddy” which makes it a challenge to alter its SSD. This is also physically large with its 2.5” size. This is another important consideration to take note of.


These modules have internal batteries that are powerful enough to last for seven hours. This figure is determined after Apple conducted a test. Moreover, these batteries are glued in a permanent place. There were reports though saying that battery replacement in 13-Inch models is not much of a tedious process than that of the 15-Inch lines.
