Remember, they're selling chips for smart TVs too where you can use as much power as you want and install a heatsink + FAN

Got it!
XBOX One with its hundred watts has 1.31 TFLOPS of GPU computing power. 2 years later, PowerVR release 1 TFLOPS GPU with single digit watts. How come it is possible ?
AnonD-312360, 10 Nov 2014"Most Games on Ios are desktop like quality" .... ha ha, ..................... ha ha... moreyeah im frommm india and i can tell u that all my game are built in quality...im made of quality...good quality...u should buy a moto e excelle nt quality desktop quality...ur poor pocket deserves a good budget.

Unless its a joke , or you're unaware of what a gaming rig is, ... or you're just fooling around... which is it ??
[deleted post]Adreno 305 performs 25 GFLOPs, GT7900 performs 1500 GFLOPs.

Could, yet they don't seems to have plans for reference card design and branded Windows, Debian and MacOS X drivers.

Anonymous, 10 Nov 2014If it is all marketing talk, how come Battlefield 4 is running on a mobile device using PowerV... moreAnd you do not see the trade offs they had to make to get it to run? Or are you thinking it's the exact same engine on the desktop? Then nope not even by a long shot. The engines are designed to scale according to hardware limitations. It's not magical for the engine to produce the same level of eye candy on all kinds of GPUs, common sense. Now if that were to be true, we don't need 250 watt GPUs to do the same thing.
Also GFLOPs means nothing without taking microarch into context and what it's exactly computing in FP.
AnonD-259899, 10 Nov 2014It's all marketing talk. Those who are familiar with 3D engines and how optimizations are done... moreand remember that most of eye candy games for mobile devices are really simple in every other aspect of the game, especially controls and level design(and time you play it because of it). 90% of them are linear and scripted.
Of course someone can say that: look at GTA SA. well GTA:SA is really simple game in terms of graphic its still the same engine like in first GTA3 and they just add few FX effects. And most of models(building trees) are made from several poligons.
The same with Portal that was running on tegra device, its source engine but portal is still really simple game, theres not that much to render compared to even HL2(more open terrians, more models and more dynamic world)
And most importand remember about battery, you probably could run Crysis... but before it load first scene your phone would be dead xD

Those who are familiar with 3D engines and how optimizations are done will instantly realize you can fake a lot more than what rasterization already achieves.
Crysis? be realistic, if you keep aside the slide decks from the marketing firms and look at the graphics for what they are they are like 2005 levels on PC at best. Clever routines that are subset of OpenGL and DX can be utilized in a way it's not obvious to the viewer at speed where the losses are not obvious but they are there, you just need to know where and how to look for them. Apples to Apples comparison Mobile GPUs are vastly way behind anything on the desktop side or even the laptop discrete GPU side. This is not even taking into account the complexities involved in the AIs and level of input interaction consoles or PCs have compared to something that so neutered as touch based gaming.
Sure in a few years time maybe mobiles will achieve what PCs can do in 2010 or 2011 top end desktop graphics but by then PC level graphics will move ahead by leaps and bounds, it's all relative. The future of PC gaming is ray-tracing not rasterization. Rasterization is a stop gap until compute capabilities on desktop evolve to the point we can real-time full ray-tracing on commercial GPUs.
That's where apple with ipads teach everyone else. Powerful gpu's lead to good quality apps. Love infinity blade,kotor...
Now if the Ipad air 3 gpu would be the GT7900. How would android gpu manufacturers catch up when the 7900 is a 512 ALU? It's like having a 512 bit gpu. And most games on ios are desktop class quality.
It's impressive where mobile gpus have gone. It's equally impressive how remarkably underused they are. They can probably render Crysis on high settings and satisfying FPS yet (in practice) they struggle to render visuals from 10 years past or even before that.
We need some magical coding sauce which would let video game designers to make use of this remarkable power on tap (and don't tell me that mobile devices are not ideal for gaming, actually a tablet+a controller *is* the ideal gaming device, high fidelity games on relatively big screen on the go...)
