Moving, actually (copying), a computer moves nothing is only the last action in the graphics chain. You need to calculate what the pixels will be. Render all the polygons, fill and shade.

That is what graphics cards do.

What makes you think there isn't a graphics processor in the iPhone 6s? There is. You do not know what you are talking about. That's exactly what the dedicated graphics processor in the iPhone handles, polygons, shading, filling, etc, very rapidly. Graphic cards and processors are not just limited to desktops and laptop computers, you obviously DON'T know. . . or you wouldn't be making such fatuously idiotic statements as you just did. You just revealed your total ignorance of what the benchmarks are and what they do.

For sure, but they get hot, that’s the primary challenge. Modern high end graphics processors are nearly super computers in their own right.

haven’t heard the fan on my 5S come on yet.

From what little I know of gaming code, it seems like most of the game is shifted from the CPU over to the GPU (video card?). My take is that gamers can upgrade the video card easier than the CPU.
