    IMHO, it is also worth noting, that if one is going single-socket, they may get performance very close to 7601 at half the CPU price, with 7551P. 7601's advantage of being able to work dual-socket is not even utilized in the test platform.

    No offense, but I tend to disagree. Based on performance, these systems are pretty close. If you can get the same performance at lower power consumption due to the single socket configuration, isn't this a selling point? There are no inherent advantages of a dual socket system. Actually, it might even be harder to obtain maximum performance due to the NUMA arrangement.
    The number of sockets is also important when it comes to performance per dollar. The price of the CPU(s) alone is not necessarily the important figure. I assume, the single socket mainboard might be cheaper than the Intel mainboard.
    Valid points, will include at least the metrics on OpenBenchmarking.org in my next comparison for those interested in the power consumption / perf per Watt.

    Right I didn't do perf-per-Watt since really not comparable with being 1P vs. 2P.

    Surely it's just as comparable as all the other stats?

    Curious how much power these systems are drawing from the wall. I don't know if their configurations are close enough to provide a good comparison, but performance per watt metrics would be very helpful if they are possible.

    Are you sure EPYC has worse IPC? You state this often, but I'm pretty sure the EPYC has a superior IPC to the Xeon, but lower boost clockspeed.

    Phoronix: AMD EPYC On Ubuntu 18.10 Putting Up A Stronger Fight Against Xeon Gold

    With hitting the home stretch to Ubuntu 18.10, I've started with my usual benchmark process for checking out this next Ubuntu Linux release dubbed the Cosmic Cuttlefish. Yesterday were Ubuntu 18.10 benchmarks on seven desktop systems from Intel and AMD while next on my agenda has been checking out the server performance. Here's the first of those server tests on Ubuntu 18.10 with some initial AMD EPYC and Intel Xeon Gold tests.
