Would be interested to see this as well. Looks like TPC-DS would a big benchmark in SQL, though apparently aimed toward transaction processing... maybe more relevant when they add update/delete then.
You can try out the community version and comapre it to a small redshift instance.
I was curious, what's different about the community edition? It didn't really tell on the pricing page.
The community edition works with a single gpu and does not allow horizontal scaling.
