The 'absolute stiff' matter (P=E) can be a Fermi or Bose gas of particles with the energy spectrum εp ∼ pq in q-dimensional space, particularly εp =p3/m2 in 3-dimensional space. We obtain its pressure, particle number density and heat capacity at finite temperature. The behavior of 'absolute stiff' medium is determined by characteristic temperature Tc=6π2n/(γm2). At low temperature the heat capacity obeys the linear law CV∼ T for both fermionic and bosonic matter, the pressure of 'absolute stiff' fermions P∼ n2+O(T2), while the 'absolute stiff' Bose gas never reveals Bose-Einstein condensation.
