Disclosure: I work on the Redshift team.

The OP's cluster is a 16-node hs1.xlarge cluster (has 3 spindles per node). There's actually a more powerful node-type hs1.8xlarge which has 24 spindles on each node. More info: http://aws.amazon.com/redshift/pricing/

So it's not fair to compare Redshift performance to your Vertica cluster unless the hardware is similar.
