Yep. All mobile Core i5 CPU are dual core CPUs with Hyper Threading.

The only quad core Intel mobile CPUs are the Core i7 with the "QM" designation. If the i7 only has the "M" designation, then it too is a dual core CPU.

This is usually how it goes for mobile cpus :

Intel Pentium G -- Dual Core - no HT - slower than Core i3
Intel core i3m = Dual core only - no HT
Intel core i5m = Dual core - can be with HT or without HT
Intel Core i7m = Dual core with HT or quad core for QM models.

oic. Havn't really checked on the refreshes recently but my point still stands.

Most Mobile are dual cores usually with or without HT and are differentiated by clock speeds and how big their caches are.
