Despite reports that Apple might have tapped Taiwan Semiconductor Manufacturing Company (TSMC) to make Apple’s new A5 processor, Samsung fabricated the A5 processors currently powering the recently-released Apple iPad 2, a recent teardown by United Business Media’s (UBM) TechInsights reveals.
The conclusion was drawn by the firm after comparing the results of their teardown of the Apple A5 chip with previous results from when they studied Apple’s A4 processor.
Allan Yogasingam, a technical marketing manager for TechInsights, told UBM’s EE Times that TechInsight can “say with 100 percent certainty that this is a Samsung-made chip.”
According to TechInsights, which analyzed an A5 chip which came with an iPad 2 using optical die and SEM cross-section images, the A5 chip is able to use low power DDR2 DRAM memory and used the 45-nanometer fabrication process of Samsung.
According to the report by EE Times, a study done by IO Snoops revealed that the clock speeds for the A5 chip is also varied at about 890 MHz to 1 GHz.
In light of this, the iPad 2 is said to be utilizing advanced power management to regulate clock speeds of the A5 processor depending on how resource-demanding running applications are.
