Clarifying the 1.5TFLOPS of the SWITCH for those who just see the numbers.

The thing that is really starting to urk me is that people are trying to spin it in a way to show that their console is more powerful than it really is. But it is soooo stupid cause FP16 can apply to all current gen hardware. So switch is 1.5TF, x1 is 2.6TF, ps4 is 3.6TF, Pro is 8.4TF and Scorpio is 12 TF and etc when you get PC into mind. So it ends up being the same in relative performance, just with bigger numbers.
Sighh

Actually not if you look in the post above you and my last post, it depends on the chip. You just cannot magically make a chip half percise to run faster. Depending on how they are made it may double the perfermance of FP16 instruction or it may run at the same speed. I use registers in my answer because that is how deep my knowledge goes about these things, I'm sure there are other ways to speed of FP16 instruction other ways. But a register for all intents and purposes of this explination can only run one instruction at a time. And depending on how the chip is made to run the FP32 instructions can influance if the chip experences as speed boost. For example some 32-bit instruction are run on two 16-bit registers. So if it is optimized to do so, if you put 16-bit instructions into this register you can put another instruction at the same time in the other register and thus "twice" the speed in this case. But there are 32-bit registers that will only do one instruction at a time no matter how small the instruction is. So just looking at terms of FLOPS and Full percision/Half percision doesn't tell the entire story.

FLOPS, like Hertz before it, is just a advertising go-to word that really has no real world inpact.

Yes, I know its not a perfect analogy but the point remains the same which is about relative performance. I have no doubt what you said is true but from what I can gather, using FP16 is very situational where as majority of the softwares are made around FP32. And I m sure that at a minimum, Switch, Pro and Scorpio will most likely have it. So I will edit the other two out
