That is something most people misunderstand. The esram may only be a small fraction of the total ram, but if the gpu can do 99% of the work it has to do in esram, then you are obviously ok. How much edram/esram you need has been tested endlessly by whoever makes chips . It seems that 32MB is some kind of "sweet spot" if you look at <=1080p images. Ms has built a very complex infracstructure around the esram bottleneck to ensure they get as close as possible to 100% efficiency.
