iFixit

Following the first teardown of the new Apple TV over the weekend at XBMC.org, we get some more details from yet another teardown. They already gave the new iPad the teardown treatment, and now our friends over at iFixit ripped apart the third-generation Apple TV giving it an 8 out of 10 reparability score. The report revealed the device now has two antennas instead of one, which iFixit noted: “Apple added the new antenna to address complaints about range and signal strength.” It also discovered a Broadcom 4330 chip (same as the new iPad) with support for dual-band 2.4 GHz and 5GHz 802.11 a/b/g/n, as well as a new single-core A5 processor. iFixit noticed the new design does not rely on a thermal cooling pad, which could mean the new single-core CPU does not run as hot as earlier generations.

While we are waiting for iFixit to tear apart the new iPad so we can get a look at the device’s new 42.5-watt-hour rechargeable lithium-polymer battery, we received confirmation that the battery does take hours longer to charge than the iPad 2 (iPad 2 pictured above). We know battery life remains the same with the 70 percent larger battery going mostly toward powering the new Retina display, A5x chip, and LTE-capabilities, but we wondered last week whether the new battery could take up to 70 percent longer to charge. MG Siegler confirmed in his review on TechCrunch that charging the new iPad takes “several hours” longer compared to earlier generations:

While you might be familiar with iFixit from its in-depth teardown guides meant to provide the ultimate resource for DIYers, it also offers the necessary tools to get the job done. We told you a while back about its “iPhone oppression kit” allowing you to swap out Apple’s pentalobular screws with standard Phillips screws. Stemming from a discovery of two unused mounting points in its recent 21.5-inch and 27-inch iMac teardowns, iFixit is now providing a kit that provides all the tools necessary to install a second hard drive in your mid 2011 iMac.

With the $199 Kindle Fire out of the gate, the inevitable questions pops into mind: Which is faster overall, the Amazon or Apple tablet?

The comparison isn’t really fair because Amazon skimped on internal components, which was key to its breakthrough $199 price point. An iFixit teardown reveals Texas Instruments’ OMAP 4430 chip inside the device, also  found inside Research In Motion’s BlackBerry PlayBook tablet.

For starters, iPad 2 boots much quicker than the Amazon tablet – again, due to its more efficient dual-core processor and optimized software. Browsing the web? No surprises here either, Safari on iPad 2 stormed ahead, performing noticeably faster than Amazon’s Silk browser which offloads page rendering to the Amazon cloud. One thing to remember: In this test, Kindle Fire was loading Flash content which of course is not supported on Apple’s device.

The iPad 2’s graphics unit, praised for its nine times performance jump, helps with scrolling, which is pretty choppy most of the time on Amazon’s device. One surprising finding is that Kindle Fire streams Netflix smoother than iPad 2, most likely due to the new version of their Android client which is not yet available for Apple’s platform.

This is not the most scientific test in the world, mind you. Again, as 9to5Google noted in its quick review, there’s really no comparing Kindle Fire to iPad 2, be it on the price, overall polish, performance or shininess. As for the speed, mainstream buyers may not be interested in raw specs anymore and Amazon has priced this thing out of the range of the Samsungs and BlackBerrys of this world so it’s more of a competitor to Android tablets than to Apple.

The teardown is in progress. Notes of interest:

• The extra .05W/hrs battery increases talk time by an hour but for some reason (likely additional background processes with notifications), standby time is reduced from 300 to 200 hrs
• “Pentalobe Screws, again?”
• The A5 processor is rated at 1GHz (like iPad obv.) but is underclocked for battery saving purposes. That doesn’t mean an update (or hack) in the future could boost speed to iPad levels.
• The iPhone 4S logic board bears a close resemblance to its stateside CDMA counterpart.
• The Qualcomm chip updated from MDM6600 to MDM6610. There isn’t much out on the 6610 right now but we’re investigating.
• It looks like there really is only 512MB of RAM. AnandTech says:

The second confirmation iFixit’s teardown gives us is the size of the A5’s on-package memory: 512MB. A quick look at the image above yields the Samsung part number: K3PE4E400B-XGC1. Each highlighted E4 refers to a separate 2Gb LPDDR2 die. The A5 features a dual-channel LPDDR2 memory interface, thus requiring two 32-bit die to fully populate both channels. The final two characters in the part number (C1) refer to the DRAM’s clock period, in this case 2.5ns which indicates a 400MHz clock frequency (F=1/T). My assumption here is Samsung’s part number is actually referring to clock frequency and not data rate, implying there are a pair of LPDDR2-800 die in the PoP stack. It’s not entirely uncommon to run memory at speeds lower than they are rated for, a practice we’ve seen in graphics memory in particular for as long as I can remember, so I wouldn’t take this as proof that Apple is running at full LPDDR2-800 speeds.

We’re updating as things develop.

As with just about any new Apple product release, iFixit has torn apart the Thunderbolt cable. Why a boring cable?  iFixit has revealed that the new Thunderbolt cable actually has active chips inside, making transfers  faster.

We found two Gennum GN2033 chips in the connector, one on each side. They were flanked by other, much smaller chips that surely added to the cable’s cost: two chips labeled S6A 1JG on one side, and chips labeled 1102F SS8370 and 131 3S on the other. Of course, there were tons of little resistors (providing impedance as needed) all around the larger chips.

Thunderbolt’s release on MacBook Pros and iMacs should be followed by new Macs coming soon. Inside the cable chip housing below
