Denver 2 vs Denver

Good Day

I would like to hear what is the difference between Denver 2 vs initial Denver CPU? I read " Denver: Nvidia’s First 64-bit ARM Processor" paper to understand the CPU, but I can’t find a similar paper for the Denver 2. What is the improvements or changes in micro-architecture besides being 16nm? Does the Denver 2 CPU also decode two instructions per cycle in ARM hardware-decoder mode?

Kind Regards
