Kaveri:                4 streams, 7 endpoints
Kabini:                2 streams, 3 endpoints
Bonaire/Hawaii:        6 streams, 7 endpoints
Trinity/Richland:      4 streams, 6 endpoints
Oland:                 2 streams, 2 endpoints
Tahiti/Pitcairn/Verde: 6 streams, 6 endpoints

Endpoints would be equivalent to pins as I understand it.
