The "being able to" is an arguable part of the statement, to put it softly.
And that is precisely what I'm arguing: if they wanted to, they could have created a high-power, higher clocking version of a standard ARM core and marketed it for console use. They have been designing ARM SoCs since pre-2010, so they have the engineers and licenses.
It is not like AMD has created APUs for consoles. It just happened to have product that was easily customizable for certain needs.
... that's what semi-custom design is: you offer your various products and ways of combining them to customers and let them specify the combination they want. And Nvidia has a long and well documented history of refusing such collaborations.
NV investing into R&D of "something" that might not even end up in console, is not a realistic scenario and that is not due to lack of NV's interest to be presented in consoles.
... this is just circular reasoning. If you plan to offer a product to a market, you need to start R&D before you have contracts in place - that's how causal reality works. If they had wanted to pre-8th gen consoles, they could absolutely have pitched themselves to both Sony and MS as a viable SoC vendor for consoles. But they didn't want to, and thus it didn't happen.
This statement is based on? Right, nothing. Just speculation.
Speculation, the non-existence of
any semi-custom Nvidia SoC, their storied and well-documented resistance to collaborative design.
AMD was the only company who had things of interest from both GPU and CPU world.
It was weaker on the CPU side, but Intel's margins and Jaguar being good enough.
And Nvidia could have designed an ARM-based CPU that could have competed with Jaguar at similar power levels even back in 2012. Would it have been a bit of a challenge? Absolutely. But if they were interested in that market, they could have done it.
Last, but not least, the way NV handled things with Microsoft earlier harshly undermined relationships between the two. Microsoft didn't even bother to talk to NV for the previous gen, they just went straight to AMD.
Which again plays into their lack of interest: their "interest" was in terms of "our way or the highway", which isn't so much an expression of interest as it is saying "well, if you
really want to buy our hardware, I guess you can". If nvidia had a genuine interest in catering to the console market, they wouldn't be acting that way towards their potential partners. Assuming they're at least moderately competent, that is.
tegra soc was slow, hot and power hungry, there a reason why nintendo underclock it, to save power and have sustained performance
The Tegra X1 in the Switch was several years old even when the Switch launched, so it's hardly surprising that it wasn't amazing - but it also demonstrates really well what can be done with low performance hardware if software is designed within those constraints. Of course theoretically Nvidia could put out a chip in the same power envelope as the Switch that would absolutely trounce it today - but unless Nintendo buys one of their automotive chips this sadly doesn't seem to be materializing. Weird, really - do Nvidia not want to sell millions more chips?
