Teardown confirms presence Intel modem iPhone 7
Part of the iPhone 7 and 7 Plus line is equipped with an Intel modem, according to a teardown of the device. The iPhone uses the 7 XMM736 modem platform. Apple also uses X12 modems from Qualcomm.
The iPhone 7 which decompose Chipworks, contains a PMB9943 baseband modem with which surface of 66,4mm 2. In addition, two Smarti 5 RF transceivers provided and there is an X-736 PMU-chip for the power of the modem. All chips are part of Intel’s XMM7360 modem platform. It is the first time that Intel hardware is present in an iPhone. Rumors that Intel modem should make its appearance in the iPhone, were there longer .
In the past, Intel, Apple had been negotiating the use of the Intel Atom SOC iPhone. However, Intel did not have feet to gain ground in the mobile market and compete with its x86 chips with the low-energy arm chips. The chip giant has put its plans for smartphone chips in the refrigerator and is now focusing on other modem chips.
“We held against the light where we spent our R & D on,” says Venkata Renduchintala, vice president at Intel this. “We had a number of mobile socs which I thought they were not worth to develop it.” According Renduchintala does not mean that Intel no mobile platforms will produce more, but whether that also means that Intel yet again socs for smartphones to develop is not clear.
Besides Intel modems Apple also supplies versions of the iPhone 7 with a Qualcomm modem, the X12 MDM9645M LTE Cat. 12. This follows from the teardown by iFixit. This modem supports the CDMA network used in the United States, in contrast to the Intel-based modem. This means that the Intel versions of the iPhone 7 does not operate on the network of Verizon and Sprint. On previous iPhones could be all variants of CDMA networks. Apple has a list put online to make consumers clearly what the iPhone 7 variants does not support CDMA. The reason Apple modems both Qualcomm and Intel declines is likely that the manufacturer does not want to be dependent on a single supplier.
Chipworks also Apple A10 Fusion soc scrutinized. The processor is produced on TSMC’s 16nm FinFET-process, has a surface area of 125mm 2 and made up of 3.3 billion transistors. The -Image which are the two powerful cores, to discern the SDRAM and the GPU, but the two-efficient computing cores of the A10 prove difficult to locate. Next to the A10 includes the iPhone 7 lpddr4 RAM from Samsung, the same type used in the Apple iPhone 6s.Viewing:-158
