We study entanglement entropy and the free energy in recently constructed
holographic duals for 5d SCFTs in type IIB supergravity. The solutions exhibit
mild singularities, which could potentially complicate holographic
applications. We use the relation of the entanglement entropy for a spherical
entangling surface to the free energy of the field theory on the five sphere as
a well-motivated benchmark to assess how problematic the singularities are. The
holographic supergravity computations give well-defined results for both
quantities and they satisfy the expected relations. This supports the
interpretation of the solutions as holographic duals for 5d SCFTs and gives
first quantitative indications for the nature of the dual SCFTs
