Oh,I thought it was a bad luck on my part. When I bought the MacBook Pro, I specially requested a model with both AES-NI and RDRAND I also loaded it up with processor cores and RAM because I wanted to use it for 5 or 6 years. I don't game or stream rich media, so I don't care about bells and whistles added to to iTunes or iMovie. The biggest pressure I put on a machine are the Virtual Machines I run. The kip at the Apple Store told me the MacBook came with both. When I got the MacBook, I discovered it was the previous model year MBP (6 or 9 months old), and it lacked RDRAND (RDRAND started shipping one or two months earlier). I even deferred the purchase while waiting for the chips to ship. I was really pissed off about it because I spent over $3000 for it.
