Bold 1: They can do what MS did and utilize that 4GB for OS purposes instead of games. |
Yes they can.
Although I would hope not.
There isn't a need for an OS to gobble 4GB of DRAM on a handheld... That is a waste of power and resources.

Bold 2: I'm going to disagree here. It isn't the DEFINITIVE MEASURE of performance, but it does tell us about the hardware and how it performs. In addition, I included this information because it's one of the few things we have confirmed from the leak, not because it is the only measure. Unfortunately, CPU cores, frequency, GPU frequency, RAM amount or bandwidth, screen resolution, etc. are all just guesses at this point. Typically based on Jetson AGX hardware. |
No it doesn't.
A GPU with less Teraflops can outperform a GPU with more Teraflops in gaming.
It is a hypothetical denominator, not a real world one.
What about INT4, INT8, INT16, FP8, FP16, FP64? Your "teraflops" doesn't tell us squat about those... A game may not use single precision floating point (FP32) at all, it may use FP16, sidestepping your Teraflop counts entirely... Which is a likely proposition in the handheld space due to performance/battery life reasons.
What about Pixel/Geometry/Texture fillrates? Again. Teraflops tells us nothing about those.
At the end of the day... If we take a Radeon 5870 at 2.72 Teraflops and compare it against the Radeon 7850 at 1.76 Teraflops... By your measure and assumption, the Radeon 5870 would win due to having almost an extra Teraflop of FP32? You would be wrong.
They even have the same DRAM bandwidth of 153.6GB/s.
But the 7850 is indeed faster.
Don't take my word for it: https://www.anandtech.com/bench/product/511?vs=549
And that is comparing GPU's from the same company... Things get even crazier if we start to compare AMD and nVidia.

Bold 3: I wasn't trying to say that it wasn't as capable as the Series S because of TFLOPS alone. But given the confirmation about what is cutbacks from GA10B, as well as portable devices historical limitations and cuts to frequency to maintain appropriate battery life (see PSP, PS Vita, Switch) we already know that it isn't going to be as capable with regard to raw power. Not at the same resolution, at least. |
Doesn't need to match it in raw power. Again... TFLOPS doesn't tell the entire story. Efficiency is far more important than brute force.
nVidia tends to engineer it's GPU's to do as little work as possible ironically, hence their efficiency jump with Maxwell.
