Given the X1 used 3GB for a fairly robust interface, I don't think Series X needs 6GB.

X1 interface was likely slugging because limited CPU power. Perhaps faster storage of Series X will also help. Hence, more RAM doesn't solve the problems of bottleneck elsewhere.

My guess is they will use 4GB on the system. But I guess 10GB of RAM would be fine for given texture streaming will be utilized.

I actually found the X1/X1X's interface to be rather slow, especially when compared with a good PC or the PS4 (though Microsoft has done a fantastic job fixing things, like faster pop-ups and less intrusive ads).

Regardless, you can't ever have too much System RAM. Ever. The interface eats more from the Random Access Memory. The more of it you have, the more data it can work with (move things around, store files, open programs, etc...). Yes, a faster proc will aid in this, but there's only so much it can do when other things don't work with it (the PS3 is a prime example of this, having a slam dunk proc with slower [and less accessible] RAM for system tasks). That is why, prior to the PS4, PSN was a sluggish mess when it came to Downloads and anything involving the Friend List.

So, the more the RAM the Series X (or PS5) have, the better the machine should function (assuming other factors don't bog down the device). 

For me PSN is still a slugg on PS4 and PS4Pro, it takes to long to load anything on any area of the store.

My phone loads 10x faster.
