Now its getting really interesting: In the end you have to compare pricing for a vCore (which is a thread on a cpu) with per-thread performance on AMD vs. Intel. Does anyone know a benchmark like this? Epyc Processors are most often tested on heavy parallelizable tasks and not strictly single thread tasks.

Disclosure: I work on Google Cloud.

Performance is a tricky, multi-dimensional thing, so there are many benchmarks that try to map to different workloads. For example, specint is often used for exactly your "single threaded task" benchmark, but if what you work on is numerical computing, you mostly don't care (you want specfp at the least and even that is bad).

Some people seem to really like Coremark these days. Others like specintrate. What kind of application do you care about? I'd guess plenty of folks here can provide a better estimate with that info.
