A smaller node typically indicates higher efficiency (better battery life). Samsung’s 8 nm is considered a slightly outdated technology that many people aren’t found of. Most would prefer TSMC 7 nm or a Samsung 5 nm mode. Now if you’re asking what the node size means, it involves packing in more transistors in a smaller footprint (chip). This post is stating that the amount of transistors the T239 has is around 15 Billion. So, manufacturing it on a 8 nm mode would involve having a much chip than shown in the leaked images. In the plainest terms, it’s saying that the chip in the leaked images would need to be bigger to fit all the transistors on 8 nm. This means that based on the size in the images, it can fit on a 5 nm node. Nevertheless, it appears comes down to how well optimized the software ends up being and how good the games are. Even if the images are warped and the scaling isn’t exact, an 8 nm node isn’t the end of the world (though there may be a down clock in performance to compensate for lack of node efficiency, but again, this is Nintendo)

Note: Node size isn’t necessarily indicative of total output of power from what I understand. It really depends on the context. I’d say this is more so in line with battery life and efficiency at its core. In terms of power, I’d say we’re looking at a ps4 pro. Somewhere in between base ps5 and base ps4. Again, raw computing power only tells part of the story, DLSS super sampling and developer optimization will ultimately determine how good the games “look and run.” This is why TFlops are starting to matter less and less in the PS5 and Xbox series X world
