part of the reason why Nvidias drivers are larger is because theres a lot of functionality that nvidia throws onto as software rather than hardware. after kepler, nvidia moved the hardware scheduler off the gpu and into the driver. this resulted in lower power consumption, but higher cpu usage (reletive to amd). Its why AMD gpus fare better when paired with a aging cpu than Nvidia does.
i cant remember the article that mentions the archetectual change, but theres a few videos, one by Hardware Unboxed that goes over the phenomena.
I first learned of it when a user who was using an i7-3770k “upgraded” from an AMD R9-290 to a Nvidia 1070 for battlefield reasons (idr which one). the user essentially lost FPS because he was being heavily CPU bottlenecked due to the Nvidia GPU/Driver.

this is interesting as fuck.
where can i read more about his architectural change?
