Then once foveated rendering is working, you can bring in the 4k screens where you render high pixel density directly where your eyeball is looking, and have a lower res rendering for the rest of the 4k pixels, and not cause the entire thing to burst into flames on your face, or run at the speed of a potatoe.

what absolute tech babble tosh, a 4k screen would work fine, the new processors (even the ones rumoured for the S7) are rated already way more powerful than the previous generation and could comfortably run VR in 4k
I'm sure Samsung developers and engineers will know perfectly what can or can't be done this year or the next
people forget that it's not the apps and experience in the phones that will dictate the upgrade path, but what can be achieved with the new pro/consumer 360 cameras

for mainstream phone use, todays processors seem to work just fine with 4k, as demonstrated by sony.
Wrong the Xperia Z5 premium can only do 4k in videos and in pictures but in nothing else, not even the UI is in 4k but only 1080p and therefore less than on S6/S6edge.
The games are often not even in 1080p but 720p and then get upscalled. We are far away from games in 4k and far far away from games in stereo 4k with VR distortion and headtracking.
In 2017 we get maybe when we are lucky 1440p graphics upscalled to 4k and in 2018 if we are lucky 4k rendered VR games.

The S7 is using Qualcomm's Snapdragon 820, as opposed to S6's Exynos 7420. The 820 is around 15% faster in the single core CPU tests, and around 5% slower in multi-core CPU tests. It should run cooler than the Exynos 7420, but it won't be significantly faster.
The S6's screen runs at 2560×1440 pixels. The Xperia z5 Premium runs at 3840×2160, so not really double the "2K" screen. Still, the GPU will have to push through 2.25 times the number of pixels, maintain 60fps rendered in two eyes, and not overheat. The Snapdragon 820 isn't going to be able to pull that off.
The Xperia z5 Premium is running the Snapdragon 810, which is slower than the 820 and has a lot more overheating issues due to its rushed design. So even though the 820 is supposed to be around 54% faster than the 810, we're still not talking 30fps video playback (with hardware assist) but rather 60fps x 2 viewports x 100k textured polygons that we have to concern ourselves with.
If you know of some "tech babble tosh" that I'm not taking into account, please enlighten me. I'm looking forward to the day when mobile devices can drive VR on the 11k screens that Samsung is working on for 2020, but here in 2016 we're just not quite fast enough.
