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
