Playstation 4.5. i think it is real. but the interpretation is false.

According to some ex-ND developer we are two console generations away from 4k.

To think that in a few couple of years a next generation Playstation with games rendered in 4k arrives? It would be possible, but at what costs? How would the games look like? Either low graphical fidelity or games with longer development periods and higher expenses. Either way a next gen console up to the task would wear a higher price tag than an Xbox One at release. In a range of 600-900.-?

I think PS4.5 is an upgraded PS4. That simple. The .5 indicates an addition to the base, namely Playsation 4. Maybe just a another PS4 version (slim) or PS4+PSVR=PS4.5.

I think this is all it really is(with 4K playback for blu-ray, Netflick's etc). Sony have never done a performance upgrade via physical hardware during a generation on their home consoles except for the PS2 slim where the CPU was overclocked by a very minimal amount. Certainly not 1080P-to-2160P resolution though.

Bullshit.

It's a false rumor or it's just a PS4 playing 4K movies, it has nothing to do with gaming.

its not that complicated really. 

If you look at the original PS4 SKU, the board on those units were about 30% bigger than what the board on the current units are. And that size reduction was achieved by just using fewer (albeit higher density) RAM modules. 

Switching from a 28nm process to a 16/14nm process which is inevitable, is literally like dividing a 28nm APU into 4. They basically can make 4 14nm similarly speced APUs Using the same wafer footprint of one single 28nm APU. Typically, that translates to a smaller chip, smaller board, smaller cpu (due to lower power drain), smaller fan and heat sink..... smaller case. This case can be made significantly smaller if Sony chooses to go with a HBM APU design and just by inclusion will give the PS4 around a 3 times jump in memory bandwidth performance. Naturally that extra ommph will have to be enabled by the dev. 

Technically, Sony could make a PS4.5 using a 14nm process with a Higher clocked CPU (say up from 1.6Ghz to about 2.5Ghz/3Ghz) and a GPU with double the computer units (18 of 20Cu to 38 of 40Cu though it's more likely to be 30 of 32) and they overall chip will still be smaller than the current PS4 APU and draw less power. 

The core PS4 will still be the base of all PS4 game development and the newer models will just run the games at a higher framerate and with maybe better effects... and faster. Don't see it doing 4k gaming tho. We will also likely see some games run at 900p on the older units while they run at 1080p on the newer ones. Or some games run at 60fps as opposed to 30fps. 

Whatever the case, if Sony does this they will probably be very muted about the whole affair as to not make people say it's a new PlayStation and stem confusion. 

No. Gaming journalists are calling it PS4.5

Sony themselves just called it a PS4.1

And the marketing behind both of those are entirely different. PS4.5 sounds threatening to existing owners that don't like the idea of a more powerful system when the current one is a relative adolescent. A ps4.5 sounds like a pretty big leap. One that suggests current owners are missing out on something significant.

The way that you described it though, calling it a PS4 slim or even a Ps4.1 that's just packaged with the newer HDMI standard for 4K movies/media and a slightly more powerful GPU that allows consistent 1080P/60FPS sounds a lot more comforting if that makes sense. To me that means we're back at $400 which isn't too bad conceptually speaking. I wonder if this potential system has a form of PSVR integration.

That's because they forgot to name the console PS3D

Sony won't make the same mistake with the PS4K

Hahahaha!

My wallet says no but my heart says yes.

DANG IT!!! I have not bought my PS4 yet and I would love for my PS4 to be able to output 4K seeing as I just got a great deal on a 55 inch Samsung 4K SUHDTV for only $800 last night. I was like no freaking way! So I just had to get it. So now I am debating on waiting to see if this rumor is true but I have the Limited Edition Uncharted Bundle pre-orderd with $300 down WHAT TO DO!!!! AHHHH!!!!!

And that right there is exactly the kinda confusion I'm talking about. 

I wouldn't be surprised if the 4K is just a 4k blu-ray player and that the system will be able to output any PS4 games at atleast 60 fps for PS VR. 4k gaming could be cool but i don't see it happening.

Also it will likely be 2017 at the earliest after AMD has made the move to 14nm, unless they can have that ready before the end of the year.
