原先说好的8G给游戏 4G给系统
现在变成9G给游戏使用了

We’ll keep tuning Scorpio to empower creators to share the best versions of t
heir games. Unlocked extra GB of RAM for them, now 9GB of GDDR5
如果比较早开发，或是早就发售的游戏，不会用到9G内存，剩下的会变成快取使用。
Games that don’t use the full 9GB, the rest of the RAM will be used as a cach
e (making things load way faster, etc.). All games = better.
