I'd bet that the 12GB number comes from, at best, a dev kit. The real product will have less than that, as always happens. I'd go with 8GB at best.
I'm surprised it supports DLSS 3 because, at least in theory and in desktop parts, only Ada based GPUs support this new version. So yeah, I'm surprised Switch's 2 SoC is so modern.
Please excuse my bad English.
