This.
They are using 3GB (24gbit) memory chips instead of 4GB (32gbit). {8 bits in a byte}
It will mean it will likely have a 320bit memory bus for over a Terabyte (Maybe 1.2Tb/s?) of memory bandwidth.
4-8GB of Ram for OS/Background tasks will likely be the standard, it really depends how much they wish to upgrade the OS, the jump from the PS4 to PS5 wasn't a big OS leap, but the OS could use faster SSD storage for a swap file more effectively.
They would have done this as a cost/benefit analysis where there is a preference for speed over sheer capacity.
Handhelds today already have 24GB-32GB of Ram... And PC's have transitioned to 32GB System memory for the optimal capacity for a number of years now.

It's a 160-bit bus design with 640GB/s of memory bandwidth. It says so in the article and Kepler's post.

160-bit is insanely low... And I genuinely have my doubts.
We haven't had a console with a lower-than-256bit memory bus since the 7th gen consoles. (Ignoring the cheap budget Series S and cheap Nintendo hardware)
Xbox Series X even has a 320bit bus.
That's only going to be 100GB/s more than the Xbox Series X bandwidth, which... Whilst it's not the be-all, end-all; as efficiency is more important, it is not a huge game changer for Neural and RT stuff.
Might work for a more budget focused console (Xbox Series S-esque)
