Update: ClickHouse finished the preliminary benchmarks for 0.4-beta[0], the version we've open-sourced. If you compute the geomean across all queries and instance sizes, it comes out as 7% faster than the 0.4-preview entry[1] that was accused of cheating.
To give you a sense of how fast it is, pgrust on a c6a.2xl is faster than ClickHouse running on a c6a.metal, a machine with 24x as many cores and costs 24x as much.
Edit: And now it's been accepted: https://benchmark.clickhouse.com/
