When I wrote my first article, a lot of people said "Why are they using old technology in a space probe?"
By creating that chart, I wanted to show that a space probe is not a phone or PC. You can't just throw octa-core SoCs inside, pack it up and send it flying into the night sky.
A digression, but it's amusing how far afield they had to go to find a modern SoC with a IMG GPU (vs. the rest of the world that is to first approximation all Qualcomm, with a few Mali's running around from Samsung). Obviously the real IMG flagship is the Apple A9, but that's not co-branded appropriately.
I wouldn't call Meizu, Xiaomi or other similar brands "far afield". They ship tens of millions of devices (and soon maybe even hundreds) every year.
But not on this particular SoC. Qualcomm (with Apple and Samsung not terribly close behind) remains the volume king even in China, last I checked. This other small-vendor SoC's are gaining momentum, but they're not there yet.
The reality today is that MediaTek is number two in mobile after Qualcomm. Meizu MX5 uses a MediaTek SoC as does the new Xiaomi Redmi Note 2 and many others.
