Any of these commands gives you a better result?
$ LWS=64 GWS=128 ../run/john --test --format=sha512crypt-opencl
$ LWS=64 ../run/john --test --format=sha512crypt-opencl --verb=5
$ _TYPE=0 LWS=64 GWS=128 ../run/john --test --format=sha512crypt-opencl
IT seems you have only 48 cuda cores
../run/john --list=opencl-devices | grep 'CUDA cores'
Check if your warp size is 32 and change LWS to 32 and GWS to 96 lcm(32, 48)
$ ../run/john --list=opencl-devices | grep Warp
