16 bit floating operations require less power then 32 or 64 bits thats not a secret and is true for GPus in general. Look at FP 16 peformance on nvidia gpus. This is not anything exclusive to the PS4

No it isn't, the point here is that on PS4 and X1 a 16bits would occupy almost the same "space" as 32 so there wasn't much gain, so some twiking were made and now they basically can double (instead of a small gain) the processing when using 16bits when possible.

Secret sauce!

Btw, what's misterxmedia doing these days?

He won't be enthused about anything if isn't on a PC. The guy clearly has an agenda and is trying to make a paragraph where Eurogamer guys clearly give THEIR opinion seem like a paragraph where they reported Cerny's opinion writing in first person.

Let's get to the point here. They could either develop the checkerboard renderind technic or simply render games at 1600p or 1800p and upscale it. If the new technic did not provided any kind of image quality gain, why would they bother with it? They could just render at lower resolutions, upscale it and call it a day. So it's safe to assume that if they are actually bothering with it, it's because it provides gains.

From the screenshots we saw, it's actually quite close to a native 4K frame and probably undistinguable from a native one at some feet away. As nobody plays a PS4 game in a 70 inches TV sitting at just 3 feet, it's a smart trade-off.

The biggest problem with 4K is that the jump is too costly. I have an OC 970 and it won't cut it. Even the most powerful GPUs still suffer to achieve it as a good framerate. This stuff applied to PCs could facilitate the transition and allow more normal PCs to run 4K games at 60 fps. Because right now, we have a 4X gap in performance to do so and that's too much.

But in the end, he will just be happy about it when it arrives on PC. Remember that he is the guy that says that all console games will be on PC thanks to emulators, but conviniently forgetting that we are still waiting for PS360 emulators to boot most games created in 10+ year old platforms, so he shouldn't hold his breath waiting for it.

It just sends every thread into a downward spiral because it seems to always come from a negative perspective.  

Yes, AMD has to get credit for that.

Not that you miss much but tell me that this was intentional

You don't even get the 4.2TF. All this is just making no sense at all because no one knows the real world performance which greatly depends on many factors like CPU, caches, memory bandwidth, memory latency and bus congestion, just to name a few.

This is the theoretical maximum the GPU is specced for and it will also greatly depend on how the code is written or what the engine actually does with the hardware.

"He's not exaggerating here either"

Did you choose to skip this part of the post?

Actually the 16 bit operation would occupy the entire register. In other words you wouldn't gain anything by using it other than maybe save a tiny tiny tiny amount of ram space.
