Apple A7: Way more power than a phone needs to have
When Brian Klug joined me on the Vector podcast last week, I asked him if including the Apple A7 chipset in both the iPhone 5s and the iPad Air and Retina iPad mini meant the phone was way overpowered, or the tablets were way underpowered. He answered in the best way possible - that the phone was ridiculously overpowered. As part of his iPad Air review, Brian's colleague, Anand Lai Shimpi, puts some context to that ridiculousness. From AnandTech:
This is the first Apple SoC that’s able to deliver good amounts of memory bandwidth to all consumers. A single CPU core can use up 8GB/s of bandwidth. I’m still vetting other SoCs, but so far I haven’t come across anyone in the ARM camp that can compete with what Apple has built here. Only Intel is competitive.
As John Gruber pointed out on Daring Fireball in his review, it's roughly the same amount of raw power as a 2010 MacBook Air. That's the machine I primarily ran iMore on for a year. And now that's in my phone, and in my tablet. Insane.
