Attention, it is absolutely not the same, whether in backquotes or unquoted.
Backquotes mean that the shell tries to execute the quoted contents as a
command and substitute the standard output of that command as the result.

Please compare and see the difference:

mri.sge:~>nproc
2
mri.sge:~>CPUS=nproc
mri.sge:~>echo $CPUS
nproc
mri.sge:~>CPUS=`nproc`
mri.sge:~>echo $CPUS
2

(there are 2 cores on the test computer, mri.sge:~> being the shell prompt)
