iFixit Confirms New iPhone Has iPads A4 Chip
Posted in: Apple, ipad, iPhone, Today's Chili
In a blog post Wednesday, teardown specialist iFixit said it had confirmed that the new, unreleased Apple iPhone includes the iPad’s A4 processor.
The discovery comes from pictures posted by teardown pictures from Taoviet, which obtained the new iPhone and published video and pictures to the Web on Wednesday. iFixit, in conjunction with Chipworks, examined the photos and concluded that the iPhone uses the iPad’s A4 chip.
“The two numbers that are different are likely manufacturing numbers
(each lot of chips is stamped with a unique number to track them through
the supply chain),” the site reported. “The important numbers are:
- APL0398 339S0084 <- Apple A4
- K4X2G643GE <- 256 MB Samsung DRAM (two dies)
“Our engineers are not surprised by this finding,” iFixit said. “We were very
impressed by the extraordinarily low power consumption of the iPad, and
remarked at the time that its power consumption and board design was
much more in line with handheld devices than laptop computers.”
What is not known is whether Apple downclocked the chip below the 1-GHz used in the iPad to save power, or whether it truly has the performance of the iPad. In any case, it appears clear that the iPad and iPhone share more than just a common operating system.
