You need to re-run all those SAP H benchmark in order to actually use
SHA512 at all. Your posted ones list speed for SHA1 only (it says "Speed
for cost 1 of 1" which means SHA-1 according to the "1:sha1".
This is SHA512 speed (on my laptop with para 1):
$ ../run/john -test -form:saph -cost=4:4
Will run 8 OpenMP threads
Benchmarking: saph, SAP CODVN H (PWDSALTEDHASH) (SHA1x1024) [SHA-1/SHA-2
128/128 AVX 4x2]... (8xOMP) DONE
Speed for cost 1 (hash type [1:sha1 2:SHA256 3:SHA384 4:SHA512]) of 4,
cost 2 (iteration count) of 7500
Many salts: 1950 c/s real, 253 c/s virtual
Only one salt: 1861 c/s real, 250 c/s virtual
