Recently Sauraen on Youtube demonstrated their performance profiling on their F3DEX3 optimizations. One thing they could finally do was profile the memory latency and it is BAD! On a frame render time of 50ms, about 30ms of that is the processors just waiting on the RAM. Essentially, at least in Ocarina of time, the GPU is idle 60% of the time!

Whole video is fascinating but skip to the 29 minutes mark to see the discussion of this part.

Ram latency is bad, GPU is spending half the time doing nothing, but in return using RDRAM allowed for 2 layer PCB making whole thing insanely cheap to manufacture.
