even 8tf is not enough (if the TF alone would actually mean something). There are games that are only 1440p on xbox one x so you won't get much more with 2tf more. It always depends on the complete hardware and how much effort the developer puts into 4k optimization or 60fps optimization or visual optimization.8tf is not needed for 4k gaming. But for gaming at "4k across the board" this gen, like Cerny said, it is true. Yes, the xox is more powerful than the pro, but it doesnt have 4k across the board. Both ps4pro and xox are cheaply made consoles, neither sony nor microsoft are doing any real effort in pushing specs forward.
Forza 7 is a very well developed 4k60 game that disguises its tricks and shortcomings quite well, but then what about pcars 2 and its much more detailed simulation.
Just to use the flops, memory bandwidth, memory size, the ROP-count, ... to brute force almost everything to 4k will never happen (in the near future e.g. next-gen consoles).
The discussion about the GTX1060 TI is pointless, too. It can deliver in some situations an equal performance, but not across the board. No 500€/$ PC can at this point reach the speed of a xbox one x. This video there totally ignored some things.
- actual hardware prices (getting cheap used hardware is luck and not very realistic, I don't even get those old Intel CPUs that cheap; the 6GB 1060 alone costs $/€300 even Dec 2016)
- actual performance indications are missing (stable performance?, reduced resolution to reach the console performance)
- it has not even a 1TB harddrive (sry, but this Is really ridicules, even the HDD of the xbox one x is to small, what do you want with a 320GB HDD? Just play one game?)
- It totally misses the comfort of a console (e.g. controller, who plays a racing game with keyboard and mouse?)
- energy-levels
- noise? (almost silent PCs aren't cheap)
You can do the same with a ps4 pro. You won't currently find any PC hardware that delivers the same performance at the same price & visual fidelity. And no this has nothing to do with the magical FP16 support (which actually doesn't bring much performance).
