New MacBook Air (mid 2013) teardown
Apple’s new MacBook Air has hit the shelves, and one has made its way to the iFixit labs for dissection. Let’s take a look at what’s new in this device.
What’s interesting about the new MacBook Air is that it is surprisingly similar to the previous-generation hardware. In fact, you can count the major changes on the fingers of one hand. These are:
Larger capacity battery
Smaller SSD module
Updated AirPort card
No separate platform controller hub
New heat sink clamp
The battery is a 7.6 V, 7150mAh unit, compared to the 7.3 V, 6700mAh found in the version it replaced. This gives the MacBook Air increased battery life. with very little additional bulk.
In order to get the “up to 45% faster” flash storage compared to the previous models, Apple has switched from SATA to PCI-E. Interestingly, in order to deliver this Apple had to turn to its arch legal rival – Samsung. In fact, the flash storage is a triple win for Samsung:
Samsung S4LN053X01-8030 (ARM) flash controller
8 x Samsung K9LDGY8SIC-XCK0 16 GB flash storage
Samsung K4P2G324ED-FGC2 512 MB RAM
This is an interesting shift for Apple who has over the past few months been distancing itself from Samsung.
The revamped AirPort card features a Broadcom BCM4360, which supports 3-stream 802.11ac and Bluetooth 4.0.
Other chip highlights are as follows:
Fourth generation Intel Core i5 processor, with integrated Intel HD 5000 Graphics
Intel Z246TA38 Thunderbolt controller
Linear Technology LT3957 inverting controller
4 x Elpida F8132A1MC DDR3L RAM, total of 4 GB
Hynix H5TC4G63AFR 4 Gb synchronous DRAM
MXIC MX25L6406E 64 Mb serial flash
Texas Instruments TPS51980A synchronous buck controller
It’s clear from this upgrade that Apple didn’t feel the need to push the boat out in terms of upgrades in order to keep the MacBook Air current.
