What is the maximum data read speed for the Kepler GPU?

Question

GPGPU

I just recently started to study this topic, so the questions are probably stupid. So, I'm wondering, what is the maximum read speed from Global Memory? Let's say I'm reading 32bit numbers, reading them very optimally, using coalesced access - how many numbers can I read per second? If not difficult, then with formulas, so that you can then calculate on your own.

Answer 1

If it is very optimal, then the bandwidth of the bus limits you from above. In real examples, this is something around 30Gb / s.
