  We provide a thorough comparison of the GMHD3D code and the PLUTO4.4 code for
both two and three-dimensional hydrodynamic and magnetohydrodynamic problems.
The open-source finite-volume solver PLUTO4.4 and the in-house developed
pseudo-spectral multi-GPU solver GMHD3D both can be used to model the dynamics
and turbulent motions of astrophysical plasmas. Although GMHD3D and PLUTO4.4
utilize different implementations, it is found that simulation results for
hydrodynamic and magnetohydrodynamic problems, such as the rate of instability
growth, 3-dimensional turbulent dynamics, oscillation of kinetic & magnetic
energy, and recurrence dynamics, are remarkably similar. However, it is shown
that the pseudo spectral solver GMHD3D is significantly more superior than the
grid based solver PLUTO4.4 for certain category of physics problems.
