Switch 1 had a 720p screen with a 1080p max TV output. That’s approx a 2x increase in throughput.
With Switch 2 it’s expected to be a 1080p screen and a 4k output, that’s a 4x increase in pixel throughput. So a 2x output increase might not be adequate.
However, it is widely expected to have DLSS, which would greatly reduce that requirement.
Big time. Their chassis design will dictate performance too. They will get the best chip they can in a cost budget and then thermal/battery limits will dictate where that chip actually lies.
The steam deck is cool and a great device but the Switch 2 will be sleeker and nintendo won’t settle for a 90min battery a whiney fan, and that has trade offs.
