ClickHouse is happy to use multiple cores if the query is heavy enough. We have tested it on AMD EPYC 7351 more than a year ago and get promising results. (I have not saved them but I'll try to reproduce and post them here.)
Another case of scalability: we have also tested ClickHouse on an Aarch64 server (Cavium ThunderX2) with 224 logical cores and despite the fact that each core is 3..7 times slower than Intel E5-2650 and the code is not optimized as much as for x86_64, it was on-par in throughput of heavy queries.
There are also tests of ClickHouse on Power9 if you mind...
