There is something called Moores law i think, stating that performance is doubled at least each 24 months. So with the release in the next 15-18 months there is a good chance this is possible. And since the drivers will be only PS4 optimized there is even bigger chance this can happen without problem or big cost.
As price will drop on the components Sony will probably loose money in the beginning and earn alot at the middle or end of its cycle.
Okay wait a minute that´s enough people...for the love of god...
4K resolutions are possible on TV´s if the TV is the size of at least 80".
Sony is going to release 30.000$ TV´s capable for 4096p (so for times 1080p) but that is just for the size of it. It means that higher TV´s are going to have better quality on image.
That´s one thing.
Also Sony has 200$ blue rays in Japan that can do 4k resolution but that if you have the TV that can make 4k resolutions all together....if not you are going to be stuck in your native Full HD TV with the max that can handle...in that case 1080p.
So you´ll need both TV´s and that "blue ray 4k".
BUT movies are movies...it is content that was rendered and recorded at that "upscaled" resolution and with a proper FPS or bit-rate in that case so you can see it all smooth in your TV. Your TV (if you own a 30.000$ 80" 4k reslution one lmao) has an internal processor that can make that 4k resolution will be possible...and thanks again for the 4k blue ray 4k too who has other one.
BUUUUUUUUUUUUT GAMESSSSSS or FOR GAMES is other story my friend.
There are no GPU´s in the market that can run NATIVE 4k resolutions at all. Not even the expensive ones, not even the best ones. Yo´ll need at least 3 GPU´s and 3 or 4 monitors to make it possible. And each monitor should be at least 1080p native resolution. Still the game will not be in that resolution it will be UPSCALED to that resolution because is the one that you can see with those 4 monitors.
And the most important thing is that you don´t know how much processing power do you need to play and see it in real time with that amount of pixels in one screen...it will be so much that not even with the best CPU and GPU combined you can make it playable.
That talking about native which still doesn´t exist...upscaled is other story but you need the 80" 4k HD TV you know...and still when you upscale something which isn´t properly rendered or made in that resolution you have to stretch pixels...and do you know what happens when this happens?
I may ask ...do you own a PC? Do you play games on PC at all?
Because people talks about 4k as consoles are the top of the technology but no...consoles are not on top of anything that´s why we buy them for less money than PC´s and stuff...
It will be possible for the PS4 for being capable to do 4k resolutions but just for movies not for games...it will use the same system as Blue Ray 4k are using which has not so much to do with the GPU that makes games "run" in our console. There is a chip for that...but again you will need the TV.
Games on 4k resolutions...give me a break...
