PS5 and Xbox Series X use GDDR6. PS5 has 512MB of DDR4 that it uses as an SSD cache, but everything else is done using GDDR6. Both are fabbed on 7nm processes, and later revision PS5s use a 6nm process. They are just entering their 4th year. We won't see a new console gen for probably 3+ years. They've barely started getting non-cross gen games in any decent number. We might see a PS5 Pro, but it won't be a huge leap.
