What are the differences between CUDA compute capabilities?
What does compute capability 2.0 add over 1.3, 2.1 over 2.0, and 3.0 over 2.1?
Answer
The Compute Capabilities designate different architectures. In general, newer architectures run both CUDA programs and graphics faster than previous architectures. Note, though, that a high end card in a previous generation may be faster than a lower end card in the generation after.
From the CUDA C Programming Guide (v6.0):
