Some Calculations On The Specifications Of A 13 Inch Retina Display MacBook Pro

Apple is rumored to be working on a 13 inch Retina Display-enabled MacBook Pro to complement the 15 inch new MacBook Pro that was released in June of this year. Recent benchmark results have revealed an as-yet-unreleased MacBook Pro device (coded MacBook Pro 10,2), so with that in mind, we thought it would be fun to predict the specifications, based on proportional calculation, of the new device.

The price of the new 13 inch Retina MacBook Pro will lie somewhere between $1499 and $1599 for the base model (likely the higher price point). The higher end of that estimation stems from the fact that there is a $400 supplement for the 15 inch Retina Display model over the standard 15 inch model and if the same were applied to the non-Retina Display 13 inch MacBook Pro ($1199 base) then $1599 is the high figure. That said, the 15 inch non-Retina MacBook Pro is 50% higher in cost compared to the 13 inch non-Retina version, so if that were applied to the price of the 15 inch model, then the figure ends up being around $1499.

The weight of the 13 inch Retina MacBook Pro will likely be 3.58 pounds or 1.63 kg, which is 20% lighter than the current 13 inch MacBook Pro which weighs approximately 4.5 lbs. To compare that with a MacBook Air, that’s approximately 21% heavier than the current version of the 13 inch MacBook Air which is 2.96 pounds or 1.35 kg.

The battery life of the new 13 inch MacBook Pro is a pretty tricky thing to calculate because Apple will likely use a different processor for the smaller model, likely giving effectively the same 7 hour battery life for the 13 inch Retina model as it does for the 15 inch Retina model, making 7 hours the standard across the entire MacBook Pro line-up. However, given the current battery capacities of the non-Retina MacBook Pro models and comparing them to the 15 inch Retina version, it’s likely the new MacBook pro will have a built in 77.9-watt-hour lithium polymer battery (comparable to the 77.5-watt-hour battery found in the non-Retina 15 inch MacBook Pro, but obviously with a different shape). The new model will also likely ship with an 85W MagSafe adaptor.

The dimensions of the new MacBook Pro will likely be fairly correlative with the existing 13 inch non-Retina MacBook Pro model, with a height of 0.71 inches (1.8 cm) similar to the 15 inch model. There may be slight differences in the height and the depth of the new Retina 13 inch MacBook Pro when compared to the non Retina version. The width will be 32 cm exactly (compared to the 32.5 cm found in the non-Retina 13 inch MacBook Pro), and the depth of the 13 inch Retina model will be 22.5 cm (compared to 22.7 in the non-Retina model).

The resolution of the new 13 inch Retina MacBook Pro is relatively easy to figure out given the exact pixel doubling in both dimensions of the 15 inch Retina MacBook Pro when compared to the non-Retina model. As such, if Apple follows the same formula, the new display will max out at 2560 x 1600 pixels (compared to the 2880 x 1800 resolution found in the 15 inch version). Assuming this resolution and a 13.3 inch screen size, this will equate to an approximate pixel density of 227 pixels per inch, which is slightly higher than the approximated 220.5 pixel density of the 15 inch Retina MacBook Pro.

In terms of processor and memory performance, this isn’t something that can be calculated based on the 15 inch Retina MacBook Pro. But, according to the recent benchmark results for the MacBook Pro 10,2, the 13 inch Retina Display model will sport an Intel Core i7 dual core processor running at 2.9GHz, together with 8 GB of 1600 MHz DD3 RAM. It’s also likely that it will ship with 256GB SSD storage

So there are all the important measurements for you. Just gotta wait for Apple to release it now.  Multiple recent rumors have suggested a September launch date, so keep your hopes high and your wallet ready.

    If there is an optical drive & better graphics card I’ll consider buying this. If not, I’ll just nab a refurb of the low end 15″ non retina model.

  • Wilson Ng

    The MacBook Pro 15″ Retina has a dedicated graphics card to help push all those pixels. Recent Apple discussion board forums are ablaze about the sluggishness with display problems running amok.

    Is this Intel 4000 integrated graphics capable of running a retina display 13″ together with an extended monitor? Or will we finally see a dedicated graphics chip for the 13″ model?

    • Maiko

      Even the 15″ Retina has the Intel HD 4000. It only uses the dedicated graphics chip when it needs to tap into that power, so when you’re just going through word files or surfing the web, the integrated graphics is what’s driving those pixels. The 13″ version will be able to handle the resolution fine for normal use, but whether or not it can run graphics-intensive apps at that res is anyone’s guess.

    Predicted Specs for 13 Inch Retina Display:

    Intel Core i7 3520M 2.9GHz – 3.6GHz
    Intel Graphics 4000 switchable to NVIDIA GT 640M LE or NVIDIA GT 640M
    8GB-12GB 1600MHz DDR3 RAM
    2560-1600 Screen Resolution
    MagSafe 2/USB 3.0 x2/ Thunderbolt x1-2
    Same Design

    Predicted Price:


    It would make sense for it to cost 1699 or higher because the high end 13 Inch right now costs 1500$.

    • NNN

      the high end non retina display MBP 15 also coasts the same as the low end MBP Retina display!

  • Craphics

    It if FRIKIN sad that Apple is probably going to settle with Intel’s crappy integrated graphics. Ugh! Puhleeeeease, Apple, puhleeeeeeease use Nvidia or AMD discrete graphics in the Macbook Pro Retina!!

    Oh well, given that Intel bribed Dell 1-billion dollars for exclusivity, I guess nobody (even Apple) can pass up that kind of under-the-table money.

  • Ghostnote

    Current MacBook Pro 13″ is $1199, not $999… so a 13″ mbp w/retina will likely fall in around $1599.

      You’re right – corrected from UK prices [face palm]
