If you're counting only gaming PCs (i.e. device used mainly for demanding 3D games) you should also count only gaming Macs/iPads/iPhones. How many are there in the world?

PC's use openGL and Directx All the android devices use opengl ES. Older ios devices use opengl

>This may sound crazy, but remember there are billions of iOS devices out there in the world, and I don't think X boxes plus windows game machines count in the billions.

There should do, albeit not for gaming but most of the office software is Windows with DirectX support. You won't be playing on, though.

Android runs OpenGL ES and there are a lot more of those than iOS devices.

Are there more Android devices that actually have hardware that can actually play high end games decently? The average Android phone is a low end phone - with an average selling price of $225 for all Android phones how can they not be?

Yeah, and they still support OpenGL. The most popular iphone by a long margin is the 6, which is not exactly a graphics power house.

Based on what statistics? Who is selling all of these high end Android phones? Even Samsung is selling mostly low end phones.

Also looking at Apple's sells every year since the 6 came out, I doubt very seriously that Apple has sold more 6 phones than 6S, 7, 8, and X phones.

Also if the 6 from 2015 is not a powerhouse, neither is Samsung S8 that was just introduced last year....

OpenGL is part of the platform, they all support it. The stats page doesn't even include 'not supported' [1]

Being able to run anything slightly demanding is other thing, but you can't argue there's no support.

Also, the benchmark you linked is for application load, which is heavily influenced by storage speed and load method (android has to JIT compile sometimes) and has almost no impact from the graphics' performance other than the bus between CPU/memory and GPU

Being able to run something suboptimally doesn't turn into sales. I'm sure that the owner of a $70 Blu R1 HD is not going to be spending money on high end games.

I've yet to see anyone build a hardcore Mac gaming machine.

Oh wait, you can't.

you could make a pretty safe argument that the iMac Pro is right up there with the best gaming PCs one could buy/assemble.

It really isn't. The fastest GPU available is a Vega 64 underclocked to basically the performance of a normal Vega 56. A 1080Ti is ~50% faster. Even if you connect an external 1080Ti it's constrained by TB3 bandwidth.

You can with an external GPU.....
