This isn't a "secret sauce".

It was never even really a secret to begin with.

The fact that the Playstation 4 Pro has superior FP16 performance over the regular Playstation 4 was almost a given as the Pro uses a more modern revision of Graphics Core Next (Or at-least an older GCN design with modern underpinnings) which the last few GCN generations... There has been a stronger emphasis on FP16 performance.
Sony just took advantage of that.

However... Just so we are clear, it's less precise. It's not going to be able to be used for everything, don't expect it to solve all of the Playstation 4's lack of 4k problems. It won't.

Okay. Next Rumor please.

polaris has full fp16 support. And shows a lot of improvement in tests compared to other cards. What exactky do you mean by not as precise? Do youbknwo whst sony has done? seen the design diagrams? Know the engineers on sonys end that customized the chip? And its not a "rumor" that there is this thing/things that the Pro's GPU has (compared to a 4/5yr old GPU architecture)that makes it pound for pound better than the stock PS4 GPU..... it's a fact. 

I mean, you make these improvements sound like they are nothing or wont yeild to an all round better perfomring machine. Weird. 

I guess he means the literal definition of FP16, which is HALF precision. As opposed to 32FP single precision and 64FP double precision.

16FP is a feature that has been a while on PC GPUs and is used to boost performance specifically in games where most of the time 32FP is not needed, which means the the GPU will process faster because it has to produce only half of the precision of the usual 32FP. But as he said correctly, it does not work for everything within game which makes the application limited somewhat.
