I want to know the difference between the two parameters related to DRAM in graphics cards. The parameters are memory bandwidth in GB/s and frequency in MHz. Especially I am confused with this frequency…is this the operating frequncy of the DRAM??
I would thankful to you for clearing this doubt. By the way what is the typical value of this frequency (in MHz) for DRAMs that comes with NVIDIA graphics cards.
The factor 3 in the FLOPS calculation and the factor of 2 in the bandwidth calculation are specific to current CUDA implementations. Future cards might have different capabilities, and those factors will change.
The effects of the core clock are unobservable. (Well, perhaps if you deliberately screw with the factory setting, you could see some effect, but you shouldn’t do that. :) )
