From the outside, Apple’s iPhone 4S looks an awful lot like its predecessor, the iPhone 4. Apple fans and investors were initially so disappointed when the phone turned out not to be a more revolutionary iPhone 5, the company’s shares intially fell by more than $20 before recovering on Oct. 4, the day it was announced
Inside, the phone is similar too, but there have been some important changes from one generation to the next that have important implications for Apple’s many suppliers. According to a teardown analysis conducted by the research firm IHS iSuppli, chipmaker Intel, which last year acquired the wireless operations of the German chip concern Infineon, has been almost entirely bounced out of the 4S in favor of a set of chips from Qualcomm. The shift to Qualcomm had been rumored as far back as last September.
Before Intel acquired its wireless unit, Infineon had previously supplied Apple with a chip known as a baseband processor that Apple had used in combination with chips from from Skyworks and Triquint to work with wireless phone networks. “Qualcomm is the big winner here,” says Andrew Rassweiler, an analyst with IHS iSuppli who conducted the teardown. “It is selling Apple a whole suite of chips that adds up to about $14 to $15 per iPhone.”
Intel spent $1.4 billion to acquire Infineon’s wireless chip operations last year in a move seen as meant to shore up its presence in the wireless phone industry overall. It has struggled to win business for its Atom line of microprocessors, which are aimed at mobile devices like smart phones and tablets.
Infineon still has a small chip in the iPhone, but Rassweiler says it’s far less significant and a lot less costly than the one it supplied Apple before. “It’s almost like Apple threw them a bone with a 50-cent part after they lost a much more high profile chip that cost about $10,” he says. Intel had no comment.
ISuppli regularly conducts teardown studies of wireless phones and other consumer electronic devices in order to find out who a manufacturers vendors are — like most manufacturers, Apple prevents its suppliers from identifying themselves much as they’ve love to — but also what each part costs. The combined cost of components — analysts check on the list prices of each part — is known as a bill-of-materials (BOM) estimate that gives a fair idea how much a manufacturer, in this case Apple, makes in gross margin on each device sold. Apple doesn’t disclose its gross margin on a per-product basis but when it reported its quarterly results yesterday it said its overall gross margin was 40.3 percent.
In the case of the iPhone 4S, Rassweiler estimates that the BOM cost ranges from $188 for the 16-gigabyte version of the iPhone 4S to $207 for the 32GB version and $245 for the 64GB version. Apple and its carrier partners sell the phones for $199, $299 and $399 respectively, typically with a two-year contract for wireless service that carriers use to subsidize the cost they pay Apple.
The costliest components are the ones that determine the price: Memory chips. Apple has been known in the past to rely mostly upon South Korea’s Samsung Electronics, the world’s largest supplier of memory, and from Japan’s Toshiba. In the phone that Rassweiler’s team tore down, the memory chips came from Samsung rival Hynix Semiconductor. “That struck us as a bit of a surprise,” Rassweiler says. It’s hard not to wonder if adding Hynix to the stable of iPhone memory suppliers is a partial response by Apple to the complicated patent fight it is waging with Samsung in courtrooms around the world.
Even so, Samsung appears to be have maintained its role as the manufacturer of the Apple-designed A5 processor that provides the iPhone 4S, and also the iPad 2, with most of its computing horsepower. Some published reports in recent months had suggested that because of the patent fight, Apple might end a relationship that dates back to the original iPhone and move its chip manufacturing contract to Taiwan Semiconductor Manufacturing Co., the huge chip manufacturing foundry. Rassweiler says there’s no sign on the latest A5 chips that that has occurred. “The markings are the same as what we saw in the iPad 2,” he says. The estimated cost for the A5 chip is $15 each, he says.
Apple started designing its own chips for the iPhone and iPad products beginning in 2010 with the release of the first iPad. The chip is thought to have been designed by teams from PA Semi and Intrinsity, two privately held chip design firms that Apple acquired in 2008 and 2010 respectively.
However it’s also clear that the A5 chips is taking on more of the heavy computing lifting inside the device than the previous A4 chip, Rassweiler says. For example: The iPhone 4 contains a chip from privately held Audience Semiconductor, based in Mountain View, Calif., that handled noise cancellation. There’s no such chip inside the iPhone 4S, Rassweiler says, so it appears that noise-cancellation duties may have been moved to the beefier A5 chip itself.
Triquint Semiconductor provided a set of chips that make up a wireless transmit module that works with the wireless phone networks. Triquint has traditionally been an iPhone supplier, Rassweiler says, but the value of what it supplies to Apple appears to have dropped. One wireless chip company that has seen the value of what it supplies to Apple increase is Avago Technologies. Like Triquint, it too has been an iPhone supplier, but the overall value of the chips it supplies has gone up in the 4S.
STMicroelectronics, the European chipmaker, maintained its role as the supplier of gyroscope chips that help determine the phone’s position and rotate the screen for playing games and displaying pictures and videos. AKM Semiconductor again supplied the compass chip. Texas Instruments continued in its role supplying the chip that controls the iPhone’s display, and an audio chip.
One vendor could not be identified. Rassweiler says that Apple appears to have taken pains to hide the identity of the company that supplies the parts that that power the iPhone 4S’s highly regarded 8-megapixel camera. This is not new, and the candidates include Largan Precision Co., a Taiwanese supplier of camera modules to wireless phone companies, and Omnivision. “We don’t know exactly who makes it,” Rassweiler told me. Whoever the supplier is, Rassweiler estimates the camera added $17.60 to the cost to build the iPhone. And they’re likely to make a lot on the deal. IHS iSuppli is forecasting that Apple will sell 81 million iPhone 4Ss around the world next year.
