Why does the Playstation 3 have split memory pools?

Rules:
You can tell me abt the memory map if u desire ✨ but uh
There are also bandwidth differences up to 10gb/s between the different busses. Add the high latency of GDDR3 compared to the XDR RAM, and the fact that the Cell doesn't seem to have access to the GDDR3... The RSX having to request access from Cell puts me in mind of Pentium Ds and other really early dual core CPUs, lol.
But this basically all means that using the two pools as a single continuous memory chunk would be impossible, right? The Xbox 360 sounds much more normal to me, I would bet without knowing that the PS4 and XBO also have large caches to offset GDDR latency. The OG Xbox has a large CPU cache as well =) which seems much funnier than this weird split ram shit.
