This is because you try to crack only one burst at once. The kernel is designed in a way that it loads num_kernels * vector_size fragments at once, i.e., 4096*32 = 131072 fragments (one burst is 16320 fragments) and then time for one round is almost constant. So you need to crack as many bursts in parallel as to keep it fully saturated. If you are cracking only one burst, the CPU *is* faster. But if you submit for example 20 bursts at once (I would recommend even more, say up to 100), you will make the advantage of 2048 cores of your GPU.
PS: your /dev/sdg died, so currently it does not crack at all :-(
