sorry, I haven't looked up the actual numbers. I wanted to make the obvious point: better hardware has higher cost. either the consumer pays for it or the manufacturer. and really, would any consumer know? ask some random person to sort50% faster? The Tegra X1 in the Shield TV is 3x faster than the A8. Plus, nVidia is probably asking for quite a premium over the Shield TV because they definitely can't get even a fraction of the volume orders of the Apple TV.
by performance. They'll probably move apple to the top (even if it was just an A6) and the rest would be sorted by popularity, ShieldTV might end up last. Even NVidia renamed it from Shield Console to ShieldTV, because that's the mindset and focus of those who want to buy such a device.Amazon FireTV

Sure, there are tech ppl who'd know tech details, but those most likely have a console for gaming.
I'd think going from 1080p output to 4k will sell way more than any fancy hardware inside.
