How do CUDA blocks/warps/threads map onto CUDA cores?
...8 cores.
2'. There is a big difference between 8 blocks of 48 threads and 64 blocks of 6 threads. Let's assume that your kernel has no divergence and each thread executes 10 instructions.
8 blocks with 48 threads = 16 warps * 10 instructions = 160 instructions
64 blocks with 6 threads ...
