iPad 4th Gen Teardown: 1GB of RAM and No Surprises


Those talented and fast-working folks at iFixit have completed their teardown (dissection) of the new iPad 4th gen, or iPad 4 – hot on the heels of their iPad mini teardown.

The teardown of the iPad 4 confirmed that it has 1GB of RAM, just like the iPad 3 and offered no real surprises given what Apple had already told us about the latest new iPad. Here are a few of the highlights findings from iFixit:

* As opposed to the Samsung display we found in the iPad 3, the new iPad LCD is manufactured by LG. Apple has reportedly been working to move away from Samsung as a primary supplier, so this LG display is not surprising. However, Apple often relies on multiple suppliers for a single component, meaning there are likely other LCD manufacturers lurking inside other iPad 4s.

* The battery is labeled with the same model number (A1389) as in the last round, so it’s no surprise that it’s another 3.7 V, 43 Whr package. Like the iPad 3, the battery is adhered very securely to the rear case. Since batteries are consumables that wear out, the trend of guled-in, hard-to-access batteries in iPads and other Apple devices is unfortunate.

* Chips inside include:
* Apple A6X Processor
* Hynix H2JTDG8UD2MBR 16 GB NAND Flash
* 2 x 4Gb Elpida LP DDR2 = 1 GB DRAM in two packages
* Apple 338S1116 Cirrus Logic Audio Codec
* 343S0622-A1 Dialog Semi PMIC
* Apple 338S1077 Cirrus Logic Class D Amplifier
* Broadcom BCM5974 Touch Screen Controller
* Broadcom BCM5973A1 Touch Screen Controller
* Texas Instruments CD3240B0 Touch Screen Line Driver
* 2 x Fairchild BCHAH/FDMC Voltage Regulator / Reference
* Murata 339S0171 Broadcom BCM4334 WiFi Module

* We found a 1.2MP Facetime HD camera lurking inside, with the ability to shoot 720p HD video. That’s a big improvement from the .3MP Facetime camera in the iPad 3. Compared to the iPad 3, this camera is actually slightly thicker (an extra .4 mm), but it still manages to fit into the same space.

That Other New iPad Announced Yesterday: the iPad 4th Generation

iPad 4th Gen 2X Perfomance

The iPad Mini was announced at Apple’s special event yesterday, just as was widely expected – as were a number of new Macs. The one big surprise of the day was another new iPad – the iPad 4th generation – or the iPad 4 as it’s likely to be called by most of us.

This was surprising, and frustrating to many recent iPad buyers, in large part because the new iPad, or iPad 3, was only just released 7 months ago – and it has now been displaced and apparently dropped entirely from the iPad lineup. As Alicia talked about yesterday here, the iPad lineup now consists of the iPad Mini, the iPad 2, and the new iPad 4.

As a lead-in to the introduction of the iPad 4, Tim Cook finished off a rundown of the many impressive numbers for iPad and the reasons why it is so loved by users by telling us that Apple are ‘just getting started’ with the iPad and “We’re not taking our foot off the gas”.

Phil Schiller then unveiled the iPad 4 and emphasized that the 3rd generation iPad is the best tablet in the world and the 4th generation iPad ‘just extends that lead’. When describing the performance improvements in the iPad 4 he went even further – saying it puts the iPad so far ahead of the competition that:

I can’t even see them in the rearview mirror.

So it’s worth taking a quick look at what exactly has changed and improved in the iPad 4.
