It's comparing AMD's Graphics Core Next 1.0 to nVidia's Maxwell.
Aka. Xbox One vs Switch.

It's why the Switch does as well as it does with it's ports despite significantly inferior hardware specifications on paper.

Supposedly its GCN gen2 inside the PS4.... which is the amd 250-290 line.
So if your gonna go arch to arch, lets atleast do that.

But again my point was, its more than just core arch vs core arch, not all cards are equally balanced ect.
So some cards in the line might be more effecient than others. (you just totally ignore this part both times)


Anyways heres the arch to arch thing you want so much:

A "R9 270x" is 2,560,  while a" Geforce 960" is 2,308 in Single precision flops.

Performance wise, theres like a ~13% differnce in favor of the 960.

2,560 / 2308 =  1,10%

So the R9 270x uses 10% more flops, and the 960 gets about 13% more performance.


110 x 113 = 124%.

a 24% better flop to performance ratio.

refernce:  Techpowerup.com
Search for any 960 review, and look at performance summery.

This 24% performance ratio that you calculated. Does this apply on average in general between all amd v nvidia in recent times? 

So using PS4 pro as an example, 4.2TFLOPs, If a switch 2 was to be close in performance to that, it would need to be about 3.2TFLOPS? 

If that is correct then as my original post I am not sure what tech the others think a mobile chip that runs at 10watts could be released in the next 2 years to even come close to that. I mean the tech available it may be able to run in portable mode at 720p?

PS5 is rumored to be 9.2 TFLOPS. Even if Nintendo managed to make a system like that with 3.2TFLOPS, it will struggle to get ports and the effort to port down is far more costly than porting the game to three platforms with similar performance.

I just can't see how Nintendo will bring this raw power game in the next 10-20 years if they continue down the switch approach. 

unless, have 3rd party developer tools become so good and versatile that they can simply scale down 4K to 720p gfx easily for portable mode? Granted lighting effects would be reduced etc but if this can be done with say a months work, then ports make be cost effective. If it takes a year to port the game to Switch 2, then devs will most likely skip.
