By investigating the SU (3) gauge theory thermodynamics on lattices of various sizes we can control finite lattice cutoff effects. We calculate the pressure and energy density on lattices with temporal extent N_=4, 6, and 8 and spatial extent N_=16 and 32, and extrapolate to the continuum limit. We find a deviation from ideal gas behavior of (15-20) %, even at temperatures as high as T3T₂. A calculation of the critical temperature for N_=8 and 12 and the string tension for N_=32 is performed to fix the temperature scale, yielding T₂{}=0. 629 (3) in the continuum limit.
