That's true although actually more RMs doesn't give you more memory as the
textures are duplicated across each RM. The big benefits of more RMs are bigger
frame buffer ( deeper pixels ) and greatly increased texture and fill
bandwidth. The biggest single physical texture is still limited by the size of
a single RM. Each RM is divided into 2 banks so you can load a single texture
up to 1xRMsize/2

Cheers
