Abstract
The causal entropy bound (CEB) is confronted with recent explicit entropy c alculations in weakly and strongly coupled conformal held theories (CFTs) i n arbitrary dimension D. For CFTs with a large number of fields, N, the CEB is found to be valid for temperatures not exceeding a value of order M-P/N 1/D-2. in agreement with large N bounds in generic cut-off theories of grav ity, and with the generalized second law. It is also shown that for a large class of models including high-temperature weakly coupled CFTs and strongl y coupled CFTs with AdS duals, the CEB, despite the fact that it relates ex tensive quantities, is equivalent to (a generalization on a purely holograp hic entropy bound proposed by E.
