When talking about stiffness, the material is only part of the equation.
You will never find steel, Al, and CF frames all made with the same tubing dimensions and wall thicknesses.
You can make a stiff frame, or a flexy frame from *any* material, just by varying dimensions.
Therefore asking how two frames compare, just based on material, is meaningless.
