• Kindle Fire HD Teardown

    Notice the "X" designation on the SoC, which means that it's an experimental device. TI normally sells "X" devices to customers before they've worked out all the bugs in the chip.

Amazon probably thought they could save some money by using these parts, which likely come from excess stock.
