SpletSee this answer for some discussion of bcrypt vs PBKDF2. Though SHA-256-crypt is not PBKDF2, it is similar enough in its performance behaviour on GPU, so the same conclusions apply. Case for SHA-512 is a bit less clear because existing GPU are much better at using 32-bit integers than 64-bit, and SHA-512 uses mostly 64-bit operations.
