The A8X In The iPad Air 2 22 October 2014 bzamayo.com/ipad-air-2-daring-fireball Daring Fireball: But Geekbench only measures CPU performance — year-over-year, the iPad Air 2 is even more impressive in terms of GPU performance. Apple claims, “The A8X chip has an astonishing 2.5 times the graphics performance of the A7 chip,” and from what I’ve seen, that’s true. The iPad is no longer following in the wake of the iPhone, performance- and specs-wise. It’s forging ahead. With 2 GB of RAM, it’s a year ahead of the iPhone (we hope) in that department. Performance-wise it’s fast enough to replace a MacBook Air for many, many people. The demos that Apple chose for last week’s event — the Pixelmator image editor and Replay real-time video editor — emphasize that. Those are performance-heavy tasks, and the iPad Air 2 handled them with aplomb. The gap between the iPad’s hardware capabilities and iOS’ software capabilities grows further. Apple isn’t known for overspeccing their devices. There’s something we aren’t seeing yet, for sure.
