With prices in the range $2,000 - $20,000 for the CPU, plus a couple grand for at least MB, cooler, memory and PSU, the journalist must be very well funded to spend that much for publishing one article analyzing the CPU.

I would like to read such an article or to be able to test myself such a CPU, but my curiosity is not so great as to make me spend such money.

For now, the best one can do is to examine the results of general-purpose benchmarks published on sites like:

https://www.servethehome.com/

https://www.phoronix.com/

where Intel, AMD or Ampere send some review systems with Xeon, Epyc or Arm-based server CPUs.

These sites are useful, but a more thorough micro-architectural investigation would have been nice.
