The initial hash values for SHA-512 are the 64-bit binary expansion of the fractional part of the square root of the 9th through 16th primes (23, 29, 31, ..., 53). That is:
$$I_0 = \left \lfloor \mathrm{frac} \left (\sqrt{23} \right ) · 2^{64} \right \rfloor$$
$$I_1 = \left \lfloor \mathrm{frac} \left (\sqrt{29} \right ) · 2^{64} \right \rfloor$$
$$\cdots$$

The simplest and obvious solution is to just do it. JTR (or any decent password cracker) will show a realtime ETC and this is much better than speculating endlessly about hardware specifications.
But if you must, read on...
This is highly dependent on the number of iterations you used for the KDF. But you can calculate it easily. Suppose selecting one ...
