rendering-cpu,gpu

[Gabe Markman]

hi i need help, cpu can render images right, a gpu can do it too. what is the cpu doing while the gpu is rendering and why would u need a good cpu for gaming if the gpu is rendring images?

[Moonzy]

cpu = does calculation

gpu = takes the calculation and draws image based on it

 

lets say an apple is falling,

 

cpu says apple is at X location now

then the gpu paints the apple at X location

 

then next frame, the apple is now at Y location based on cpu's calculation

then the gpu will paint the apple at Y location

 

this is in layman's term `-`

 

so if your cpu cant calculate fast enough, your gpu would be doing nothing (no picture drawn = lag/stutters)

if your gpu cant paint fast enough, the cpu will be doing nothing (not much lag or stutter since the gpu is still drawing at almost the same pace as before)

 

so its best to be balanced or atleast, have a fast cpu, since having cpu as a bottleneck in games is undesirable

while a gpu bottlenecking is normal
