8nm Sammy and 5/4nm TSMC are estimated to be nearly the same price after factoring transistor density and increased yields. 

Nobody said TSMC 6nm and TSMC 5/4nm, were (although as prices change and 5/4nm mature they might get closer.) 

Again, Nintendo can't just choose any node. They have to choose the nodes that Nvidia has purchased for their other chips. Nvidia isn't purchasing TSMC 6nm wafers. The options are Sammy 8nm/7nm, or TSMC 5/4nm. 

A (final cost of Sammy 8nm chip) ~= B ( final cost of TSMC 5nm chip) <=/=> B (final cost of TSMC 5nm chip) ~=C  (final cost of TSMC 6nm chip.)

I'm certain it's gonna be 8nm but good luck. i read enough and use common sense to know that 8nm is 99% happening. what do you think the odds are for 5nm 50%?

If it is a T239, I am almost certain it is going to be something other than 8nm. 

For the very good reasons presented by those with the computer engineering knowledge. 

It comes down to this: why would Nintendo and Nvidia go with 12SM if 6SM or 4SM would be cheaper and provide better performance? 

But we know the T239 is 12SM from the leak. 

So either the Switch 2 will consume a lot more power than we think, or they are using a different node. 

I'd give it an 80% chance it is the latter and a 20% chance it is the prior.

The fact that you are 99% certain about something you have very little domain knowledge of should give you pause.
