Also, the difference in sub-NUMA configuration actually favors AMD as well. NPS=4 is optimal for AMD, as shown by ServeTheHome's own work earlier. Both systems are tested in their proper (fastest) configuration. Despite ServeTheHome's own previous work showing this, they're whining about it being different. But if Intel hadn't tested AMD in the proper configuration they would have complained about that too. Yeah, you take first-party benchmarks with a big grain of salt like always, but STH is just looking to stir some shit here.

> Both systems are tested in their proper (fastest) configuration. AMD is running at half the threads it can. I'm pretty sure that's not its proper nor fastest configuration.

oh really one thread per core is the optimum for EPYC server? I don't know why AMD care about hyper threading then.

  I don't see where I said one thread per core was optimal for Epyc or not.

  BTW turns out that was a typo and they used two threads per core anyway.

  We're not talking about the general case. One thread per core might be optimal for that specific workload.
