Questions about Fill rates and Low resolutions

alrighty, what's this whole thing about fillrates and low resolutions concerning games (fps mainly)? what's the bottleneck, the video card or the cpu? and is the the opposite when games are run at high resolutions?
 
Low resolution = CPU bottleneck
High resolution = Vid card bottleneck

Look at it this way...

Rendering at 1600x1200 takes 4x as much fillrate as 800x600 to maintain the same framerate. So if a video card is capable of 60+ fps @ 1600x1200, it could do 240 or so at 800x600. Yet there's no CPU that can keep up with that.

Viper GTS
 
Like Viper said, and one thing keep in mind that a video cards real world fillrate is limited by memory bandwidth in all current cards (this ridiculous nonsense about a GF2 Ultra doing 2Gigatexels/s is a joke, the core can handle it but with 32bit frame and Z-buffers it doesn't have memory bandwidth to sustain it)

So for high res you want fast video card memory (or memory bandwidth saving techniques like ATi's HyperZ) and at low res it's CPU like Viper said.
 
ahh, so that's how it is. hmm. if next generation game consoles only run at 640x480 (or sumptin like that) then i guess they would need pretty fast cpus right?
