First, I appologize if this belongs in the laptop section rather than the Graphics Card section. My question: I was wondering how much of a disadvantage the less expensive GT 650m would be compared to the more expensive GTX 660m?
Nvidia's specs for the two GPUs seem to be very similar, sometimes even favoring the GT 650m. And, yes, I realize the "up to" statement in the GT 650m's clock specs makes it suspect. Maybe someone could shed some light on what the actual clock speed is for the 650m and why "up to" is even used. Thank you.
GT 650m
384 cores
Up to 900 MHz
128bit mem
Up to 80.0 GB/sec
GDDR5
GTX 660m
384 cores
835 MHz
128bit mem
64.0 GB/sec
GDDR5
