Perform window to viewport transformation for the point (20,15). Assume that $(X_{wmin}\ ,Y_{wmin} )$ is $(0,0)$ ; $(X_{wmax}\ ,Y_{wmax} )$ is $(100,100)$ ; $(X_{vmin}\ ,Y_{vmin} )$ is $(5,5)$ ; $(X_{vmax}\ ,Y_{vmax} )$ is $(20,20)$ . The value of $x$ and $y$ in the viewport is $x=4,y=4$ $x=3,y=3$ $x=8,y=7.25$ $x=3,y=4$

I have a confusion that how the Gpu internal memory different from primary memory in the sense when which of the memory is active. For example suppose i am doing GPU programming or playing a video game then primary memory plays a role or only GPU memory. Suppose I increased my RAM without touching GPU will there be any improvement in my Gpu programming or my video games.
