The new single-core A5 processor in the new Apple TV does not havea thermal pad, suggesting it runs even cooler than its predecessordespite offering high-definition 1080p video. Though the previous, second-generation Apple TV featured a thermalpad with its A4 processor, the new 1080p-capable Apple TV does nothave a thermal pad, marking one of the few major differences in thedesign of the new set-top box. The lack of a thermal pad wasdiscovered in a teardown of the new Apple TV conducted by iFixit on Monday. The design of the components in the new Apple TV suggests thecustom single-core processor found in the set-top box puts off less heat than its predecessor.The device still has the same power supply, though, providing 3.4Vat 1.57A. Even though it apparently runs cooler, the new CPU is more capableand allows users to output 1080p high-definition video content. And though it doesn't have a thermal pad, it does feature a metalheat sink that rests atop a small thermal plate, a design identicalto the previous Apple TV. Previous uses of the A5 chip in the iPad 2 and iPhone 4S featured adual-core CPU design. The A5X chip in the new iPad also features adual-core CPU, accompanied by a quad-core graphics processor. An earlier disassembly of the new Apple TV discovered that the updated set-top boxfeatures the same 8 gigabytes of storage as its predecessor, butthe system RAM has been doubled to 512 megabytes. And supporting what was previously discovered, Monday's latest peekinside the Apple TV also found two antennae inside the device. Theaddition is presumed to boost signal strength in the latest AppleTV. "We're suspecting that this Apple TV is preserving the 2.4GHzshared antenna, but has also added a second antenna for 5 GHzconnectivity," the solutions provider wrote. iFixit's teardown of the Apple TV declared the device"significantly easier to crack open" than the iPad 3. Thediminutive size of the device aids in its repairability, as it hasfew components within its case. Chips featured on the bottom side of the logic board are: Apple A5 single-core processor Toshiba THGVX1G6D2HLA01 8GB NAND Flash Broadcomm BCM4330 (appears to be the same chip in the iPad 3rdGeneration) Apple 343S0479 Apple 338S1040 And on the back of the logic board, the following chips can also befound: SMSC LAN9730 standalone USB to ethernet controller V301 DELTA 8456E-R 54418 TXC Mn40 25.000.
