The similarities and differences of the pressure and magnetic field phase diagrams of the heavy fermion systems CeRh2Si2CeRh2Si2 and YbRh2Si2YbRh2Si2 are reviewed. In CeRh2Si2CeRh2Si2 the transition from antiferromagnetic order to a paramagnetic state seems to be first order with a clear volume discontinuity. Drastic differences appear not only in the pressure dependence of their Néel temperature but also in their magnetic field response as a comparison of the CeRu2Si2CeRu2Si2 case with YbRh2Si2YbRh2Si2 shows which reflects the position of their quantum critical field with respect to the magnetic field Kondo scale. However, a new generation of experiments in extreme conditions is required: very high magnetic field for CeRh2Si2CeRh2Si2, very low temperature for YbRh2Si2YbRh2Si2.
