•Deep pipeline
•Always have to go through all stages
•Pipelines always clocking
•Fast, but too much power consumption
•~750mW per 100M pixel/sec
(~200 pipe stages)
Traditional graphics architecture.
•Optimized for OpenGL-style fast texturing
•Very deep pipeline (around 200 stages)
•Data through all stages
•All stages always clocking, utilizing power regardless of whether or not they are actually doing useful work.
•Typically these traditional pipelines use around 750mW per 100 mega-pixels per second of graphics work
•Very power hungry
•Very fast because of dedicated units but power intensive
•Not well-suited for low-powered devices
