Typically, the reference for high resolution and high intensity in powder diffraction is the use of the synchrotron radiation. However getting access to such large scale facilities might be a tedious task and definitively not as often as one would like. Consequently, it is important to know how far one can push the limits of a powder diffraction in the laboratory. Using various examples of materials, from perovskite materials, to permanent magnets or mineralogical related materials; we will review what can be done in the laboratory and see how it can compete with synchrotron radiation in some instances.
