Updated the title to fix the error there.

More updates today, Resetera industy insider Nate the Great has put out a podcast and has said he has also heard the Matrix Awakens demo was shown and sheds more light on the Zelda: BOTW demo:



He says The Matrix Awakens was running with ray tracing and uses no ray reconstruction. I don't really know how this is possible, but that's what he's saying. If that's the case, then I almost wonder if this has to be Lovelace architecture and not Ampere. Kopite when he first leaked the Tegra T239 said it was Lovelace but I dunno I think we just assumed Ampere? If it's Lovelace I think that means it has to be a 4nm chip because Lovelace is 4nm or lower only from what I understand. 

Lovelace did start shipping in fall 2022 (Nvidia 40 series cards), so if the Switch 2 is fall 2024, it would be a two year gap there ... it isn't actually too far off from the Tegra X1 releasing in 2015 (Maxwell 20nm process), and Switch launching in early 2017 I guess (probably not unreasonable to think Nintendo was targeting holiday 2016 and just missed it due to software not being ready). The other can of worms Lovelace opens up is it would potentially open the door to DLSS Frame Generation (I said potentially) as that is supported by Lovelace architecture which could alter performance quite a bit in a good way. 

Zelda: BOTW demo was 4K 60 fps using DLSS but the interesting quirk was all the load time was eliminated. So as I've said before I suspect Nintendo is using some faster internal storage, maybe like UFS 3.1 or 4? An internal NVMe seems like it would be too expensive ... but who knows. 

A person on reddit posted a very detailed speculation for why they think 4nm makes the most sense from both a business perspective and a technological one and for both Nintendo and Nvidia.

The prices of NVMe drives have been crashing in the last 6 months or so. A regular consumer can get a 512GB one for about $25, and Nintendo will get it even cheaper.
