Comparing Apple's new 2018 13-inch MacBook Air to the 12-inch MacBook

MacBook versus MacBook Air

Continuing our ongoing MacBook comparison series, we pit the 2017 12-inch MacBook against the 2018 13-inch MacBook Air, the latter of which was recently revamped with a refreshed design, Retina display, Touch ID and more.

Starting with design, both the 12-inch MacBook and MacBook Air feature iconic wedge shape chassis, a silhouette introduced with the original Air more than ten years ago.

In terms of portability, the MacBook obviously beats out the larger 13-inch Air, with a much smaller, thinner and lighter chassis. That said, the Air is not a beast by any means, having had both its footprint and weight reduced from last year's iteration.

Comparing the contrast of the 13-inch MacBook Air and the 12-inch MacBook

Both MacBooks pack a 2,560-by-1,600 pixel resolution display, but the 12-inch MacBook's screen gets quite a bit brighter than the one on the Air. The 13-inch MacBook Air also lacks contrast and looks more gray in comparison. FaceTime cameras are embedded in the top bezel of each Mac, though the 12-inch MacBook's 480p module is a far cry from the 720p HD unit in the 13-inch MacBook Air. Microphone quality on the Air is much better as well.

Both models have Force Touch trackpads, with the Air's being a bit larger.

As for keyboards, the Air features Apple's third-generation butterfly switch keyboard, which includes a silicone barrier beneath the keys to help block debris from getting in the mechanism. The 12-inch MacBook was introduced last year and comes with Apple's second-generation keyboard that is more prone to failure.

Expandability is constrained on the 12-inch MacBook and its single USB-C port. The Air, on the other hand, has two Thunderbolt 3 ports that are capable of transferring data at up to 40 Gbps. You can also connect peripherals like eGPUs and external monitors to the Air for a better desktop computer experience.

The MacBook edges out the 13-inch MacBook Air in terms of thinness.

As usual, Apple improved on its speaker design with this year's Air. Compared to the MacBook, Air's speakers are louder and boast more bass.

Unlike the 12-inch MacBook, the MacBook Air comes with Touch ID, which is nice addition for keeping your computer secure. It also enables Apple Pay. Touch ID means Air gets Apple's T2 security chip. The custom silicon handles SSD encryption and other system tasks, including repair authorization for certain critical parts like Touch ID and the logic board.

Performance

The MacBook Air scored 20 percent higher than the 12-inch MacBook in Geekbench 4's CPU test, and 22 percent higher in the GPU evaluation.

Based on this, the Air seems to perform quite a bit better, and it also has a fan to cool the system down. Interestingly, the fan isn't actually connected to the processor's heatsink like it is in the MacBook Pro or even the old MacBook Air.

To test the thermals, we performed Cinebench R15's CPU test runs back-to-back while using Intel's Power Gadget to keep an eye on the temperatures. The 12-inch MacBook averaged 253.8 points after five runs, and the processor floated at around 95 to 99 degrees Celsius. The 13-inch MacBook Air averaged 261 points and it stayed at around 99 to 100 degrees Celsius basically the entire time.

Notably, the Air's 20 percent Geekbench lead dropped all the way down to 3 percent while stress testing, and the Air's fans were blowing pretty loudly the whole time.

In terms of battery life, the Air will get you 12 hours compared to only 10 on the 12-inch MacBook, mostly due to a larger battery.

Which is right for you?

If you do a lot of traveling or you just want to have an ultra portable laptop, then get the 12-inch MacBook. The $1,299 base price nets a better display, completely fan-less design and larger 256GB storage drive when compared to the 2018 Air.

The extra inch of screen size makes the MacBook Pro a much larger device overall

If you're someone who wants the best battery life, need extra ports and Thunderbolt 3, like to video chat and want the latest technology like Touch ID, T2 and the third-gen keyboard, then the 13-inch MacBook Air is the correct choice.
