90Hz refresh rate. Faster memory tuning (5500 > 6400 MT/s), which is a tangible performance uplift. Torx screws into metal threads for the case so you can open it up safely.
I am simultaneously ecstatic for newcomers who get to enjoy it, and feeling just a bit dunked on. At least I got one of the nice 512 cases.
The question is, how is the ssd swap? Easy as on the OG SteamDeck or more difficult.
Easier, if you want to, due to the Torx screws - but there’s now a 1TB SSD tier.
