What are all the differences between the 15-Inch "Early 2013" Retina Display MacBook Pro models and the "Mid-2012" models replaced?
Please note that all notebooks mentioned in this Q&A have been discontinued. However, this Q&A is up-to-date and can be quite helpful for anyone buying or selling one of these models on the used market.
The 15-Inch "Early 2013" Retina Display MacBook Pro models -- the MacBook Pro "Core i7" 2.4 15" (Retina 2013), "Core i7" 2.7 15" (Retina 2013), and "Core i7" 2.8 15" (Retina 2013) -- are quite similar to the "Mid-2012" Retina Display MacBook Pro models replaced -- the MacBook Pro "Core i7" 2.3 15" (Retina), "Core i7" 2.6 15" (Retina), and MacBook Pro "Core i7" 2.7 15" (Retina).
In fact, these lines only are differentiated by processors, configurations, and identifiers. However, as each series is so similar -- and models easily can be mistaken for one another -- an in-depth evaluation of both the similarities and differences can be quite useful.

External Similarities
The "Mid-2012" and "Early 2013" Retina Display MacBook Pro lines both use the same essentially "sealed" wafer thin aluminum and glass design. Unlike the MacBook Air, which is tapered from back to front, the 15-Inch Retina Display MacBook Pro models are uniformly 0.71 of an inch thick, 14.13 inches wide, and 9.73 inches deep when closed and weigh a little less than 4.5 pounds.
All of these models have the same high-resolution LED-backlit 15.4" widescreen 2880x1800 (220 ppi) "Retina" display, full-size "chiclet-style" backlit keyboard, a glass "no button" trackpad with "inertial scrolling" support, integrated stereo speakers and an integrated 720p FaceTime HD webcam. None have a built-in optical drive.
Connectivity Similarities
Connectivity is identical for both lines and includes 3-stream 802.11a/b/g/n, Bluetooth 4.0, two USB 3.0 ports, two "Thunderbolt" ports, an HDMI port, an audio out port, an SDXC card slot, and a "MagSafe 2" power connector port.
These models do not have Gigabit Ethernet or Firewire "800," although Thunderbolt-to-Gigabit Ethernet and Thunderbolt-to-Firewire 800 adapters are available at additional cost.
Identification Differences
The "Mid-2012" and "Early 2013" Retina Display MacBook Pro models share the same external A1398 model number and the same MacBookPro10,1 model identifier in software.
Consequently, the EMC number is better for more unique external identification. Specifically, the 15-Inch "Mid-2012" Retina Display MacBook Pro models are EMC number 2512 and the "Early 2013" Retina Display MacBook Pro models are EMC number 2673. As always, EveryMac.com has painstakingly hand documented these details for your convenience.
Finally, EveryMac.com's Ultimate Mac Lookup feature additionally can uniquely identify each of the Retina Display MacBook Pro models by their serial numbers.
Internal Similarities & Differences
Internally, the 15-Inch "Mid-2012" and "Early 2013" Retina Display MacBook Pro are quite similar. Both lines use the same "Ivy Bridge" architecture with quad core Intel "Core i7" processors of differing clockspeed, onboard 1600 MHz DDR3L SDRAM that is soldered in place and cannot be upgraded after purchase, and dual graphics processors -- a NVIDIA GeForce GT 650M with 1 GB of dedicated GDDR5 memory and an "integrated" Intel HD Graphics 4000 graphics processor that shares system memory.
Although the internal flash storage is not intended to be upgraded after purchase, it is mounted on a removable module and it is quite possible to upgrade to a larger capacity in the future.
The built-in 95 watt-hour lithium-polymer battery provides up to 7 hours of runtime in Apple tests, although actual runtime can vary. Unfortunately, the internal battery is glued in place, which makes it effectively impossible to replace without also replacing the entire upper case even for the highly skilled.
