This remind me of an article talking about the performance of Iphone and Android processors. Actually, they are not comparable, because Apple A7 is two big processors with a lot of recourses. But Android CPU is usually four or eight small processors, it's unfair to compare them just according to their number of processors or absolute performance.

Speaking of Android, I looked up what chip is used on a Galaxy Tab 3, and it was Intel Atom Z2560 (http://ark.intel.com/products/70101/Intel-Atom-Processor-Z2560-1MB-Cache-1_60-GHz). However, although this chip has integrated GPU, it doesn't seem to have dedicated video encode/decode or an image processor. Does anyone know why that might be? It seems like a good idea to have them on mobile devices. Does it have anything to do with software video decoding?

The Intel Atom Z2560 has a PowerVR GPU in it. The PowerVR GPU carries the video decoders.
