February 23, 2013, 7:43 AM — In the latest update to the Retina MacBook Pro, some models got price cuts, some received slightly faster processors, and some got a healthy bump in the amount of RAM. Anyone who purchased a Retina MacBook Pro prior to this refresh shouldn't kick themselves for making the leap, but the reduced cost for the 13-inch models and faster performance for the 15-inch models make these thin, light, and fast laptops a better deal than ever.
Let's be specific
From the outside, the 2013 Retina MacBook Pros look identical to the 2012 models. Our previous reviews of the original 13-inch and 15-inch Retina MacBook Pros contain more details on the look and feel of these laptops. But here's a short summary of the specifications.
All of the Retina MacBook Pros have two USB 3.0 ports, two Thunderbolt ports, a MagSafe 2 power connector, a headphone jack, and an SDXD card slot. As with last year's Retina MacBook Pros, RAM is not user-upgradable; but luckily, the standard 8GB of memory is sufficient for all but the most demanding users. If you require more than 8GB of RAM, you will need to move to a 15-inch Retina MacBook Pro which can be configured with 16GB of RAM.
The 13-inch models feature LED backlit screens with 2560-by-1600-pixel resolution and a pixel density of 227 pixels per square inch. This extremely high resolution--four times higher than that of the MacBook Pros with standard screens--makes the individual pixels in an image virtually undetectable. The 13-inch Retina MacBook Pro is just 0.75 inch thick and weighs 3.57 pounds. The non-Retina 13-inch MacBook Pro is 0.95 inch thick and weighs 4.5 pounds.
