How Many Teraflops Does my computer have? Why do console gamers have HDR and PC doesnt? How are $400 console playing 4k games?

First question how many teraflops does my computer have.

CPU: i7 6700k STOCK
RAM: 16GB DDR4 | 2x8GB 300MHz
Mohterboard: MSI Z170A Gaming M7
GPU: GTX 950 Asus Mini STOCK
PSU: EVGA 750B

My Second Question is why do console gamers have HDR? and why
doesn't PC have this feature? Usually PC is the platform that gets new technology first.

My last question is How is the $400 PS4 Pro able to play games at 4K. I've spent close to $1000 for my rig and 4k is too high and too much for my GPU

Your GTX950 can output about 1.6 Teraflops in single precision mode, but it's just a theroritocal number and it doesn't completely tell the whole story about the graphic capabilities of your GPU. The Teraflop number only refers to the compute capabilities of a GPU and it's not about its full gaming potential. That why 2 GPUs, with similar Teraflop figures, but completely different GPU architectures, won't perform similarly during gaming.

HDR console gaming requires HDR screens. Right now only HDR TVs do exist and there aren't any available HDR computer monitors in the market yet. All new GPUs are capable of HDR output and new HDR monitors will likely appear next year. That's why you currently see HDR gaming only on consoles but it...

The PS4 may be able to play games in 4K, but in reality its GPU isn't powerful enough to game at that resolution with max details. That's why almost all console games have reduced detail levels at 4K resolutions. Also don't forget that consoles are tuned to have fps limits which don't usually exist on PCs. That said your GPU is relatively weak for 4K and in fact the PS4 Pro's GPU is 3 times more powerful than yours. If you want to properly game at 4K then you want a 500+ $ GPU, so the most cost effective way is to get a PS4 Pro which is cheaper but remember that PC gaming will always look prettier if your system is powerful enough to max those detail settings.
 
Solution
lets start with a definition of what is a teraflops
teraflop, a unit of computing speed equal to one million million (1012) floating-point operations per second.
The theoretical peak FLOP/s is given by:
Number of Cores∗Average frequency∗Operations per cycle
The number of cores is easy. Average frequency should, in theory, factor in some amount of Turbo Boost (Intel) or Turbo Core (AMD), but the operating frequency is a good lower bound. The operations per cycle is architecture-dependent and can be hard to find.

I had to read up on your second question and it seems HDR on console is more a hype than anything else according to this review BY Cnet https://www.cnet.com/news/why-you-shouldnt-get-excited-about-4k-and-hdr-gaming-at-least-not-yet/
and I quote
If you don't follow gaming hardware news, we should talk briefly about the new consoles, otherwise the rest of this article will get confusing, and quick.
•PlayStation 4: Launched in 2013, no 4K gaming or HDR
•PlayStation Slim: Launched in 2016, essentially a smaller PS4
•PlayStation 4 Pro: Will launch on November 11, 2016 (originally code-named Neo), upgraded hardware, "4K capable," HDR support, no 4K UHD Blu-Ray playback
•Xbox One: Launched in 2013, no 4K gaming or HDR
• Xbox One S: Launched in 2016, slightly upgraded hardware, "upconverts" games to 4K, HDR support, 4K UHD Blu-Ray playback built-in
•Xbox One Project Scorpio: Launching holiday 2017, significant hardware upgrade, 4K gaming (claimed)

and that quote also contradict your "PS4 can play 4K" statement...

put at 1080 in your pc and you can do 4K no problem :) not 400$ but 300$ and you don't have to fiddles with silly looking box in living room. (grins)
