We prove that the Smyth powerspace Q S (X) of a topological space X is core-compact if and only if X is locally compact. As a straightforward consequence, we obtain that the Smyth powerspace construction does not preserve core-compactness generally. Besides, we prove that Q S (X) is consonant implies that X is consonant and conversely that the Smyth powerspace construction preserves consonance under some additional conditions. Furthermore, we obtain necessary conditions as well as some sufficient conditions, under which the upper topology and upper Vietoris topology on the set of non-empty compact saturated subsets of X with the reverse inclusion order coincide.
