Apple iPhone 5 uses Qualcomm Gobi MDM9615 baseband chip

If there’s one big surprise looking at the tentative virtual tear-down carried out by UBM Techinsights, it’s that the cost of the baseband modem appears to have risen by nearly 80 per cent from $14 to $25, that’s 15 per cent of the phone’s total cost of ownership, up from 10.5 per cent on the iPhone 4S.

A quick look at Apple’s official tech spec page leaves us to believe that the best candidate for the baseband modem is the MDM9615, which is a so-called world mode mobile data modem and according to Qualcomm’s documentation, supports “LTE FDD/TDD CAT3, SVLTE-DB, Release 8 DC-HSPA+, TD-SCDMA, GSM/GPRS/EDGE, EGAL, 1x Adv., EV-DO Rev. A/B”.

The MDM9615 – which was introduced at MWC in 2011 - is the voice-capable version of the MDM9600 that uses a 28nm manufacturing process rather than 45nm and as per Apple’s official literature, the chipset has a peak data rate of up to 100Mbps.

It’s also worth noting that the chipset includes its integrated application processor, a Cortex A5. Qualcomm has already released the follow-up to that chip, the MDM9625, which ads LTE Adv. Cat 4 as well as Release 10 HSPA+ to the list, boosting the peak data rates to 150Mbps, while reducing power consumption and die size. Maybe a candidate for the iPhone 5S/iPhone 6.

You can win an iPhone 5 in our iPhone 5 competition by answering a simple question about what generation the Phone 5 is. Check ITProPortal live report on Apple’s announcement. Other than theiPhone 5, we saw new iPod devices but no cheaper version of the iPhone 4S, an iPad mini and potentially a 13in Macbook Pro with Retina Display.

Desire worked at ITProPortal right at the beginning and was instrumental in turning it into the leading publication we all know and love today. He then moved on to be the Editor of TechRadarPro - a position he still holds - and has recently been reunited with ITProPortal since Future Publishing's acquisition of Net Communities.
