Does the non-Retina screen MacBook Pro have the ability to initiate Power Nap?

I've seen that the Retina screen MacBook Pros can use Power Nap from Apple's WWDC keynote but can the non-Retina screen MacBook Pros do that too? It has the same processor and close to the same RAM. Or is it because the Retina screen MacBook Pros have flash storage that they can do Power Nap? Thanks
