Clustrix relies on an Infiniband cluster interconnect, so the latency is several orders of magnitude smaller. This makes distributed transactions across shards much quicker at the cost of requiring more expensive hardware. Cassandra's query language, CQL, is not really comparable since it only supports such a small subset of SQL. Also, Cassandra uses eventual consistency in place of doing distributed transactions.
