multicore performance of CPU e3-1270 v5?

i run unixbench on my server with CPU e3-1270 v5, but why is multicore score only 6945.8
i have server with e3-1245v2 and has better multicore score 9000

this is my benchmark result:

    Maybe due to the graphics tests?

    And HDD too, can have an impact...

  • Most likely due to running it on old kernel version, A friend of mine had E3 v5 on Centos 6 the performance was a joke.

    Reinstalled to Centos 7 no performance issue.

  • HDD and Graphics can make a difference. Can you please give us a hdd test speed on both servers?

    Use the dd command to measure server throughput (write speed)

    dd if=/dev/zero of=/tmp/test1.img bs=1G count=1 oflag=dsync

  • dd if=/dev/zero of=/tmp/test1.img bs=1G count=1 oflag=dsync

    E3-1245v2 has integrated graphics, E3-1270v5 doesn't.

    Maybe something wrong with the server. Sometimes power supply can do it.

    could you give us a full detailed hardware list, a list of all running processes on each server, the OS/kernel versions and an export of all bios settings for each server?

    Without that, just turn it off and on again.

    supermicro cpu e3-1270v5
    32GB RAM (2x16GB micron 2133MHz)
    4x250ssd (1 samsung+3crucial ssd) BIOS RAID10

    CentOS Linux release 7.4.1708 (Core)

    Linux version 3.10.0-693.11.1.el7.x86_64 ([email protected]) (gcc version 4.8.5 20150623 (Red Hat 4.8.5-16) (GCC) )

    this is new server, so no process on it, just running benchmark

    how can i export bios setting?

    Honestly, performance on the E3 series really hasn't moved much since sandy bridge v1's.

    So, yea, it's almost certainly software or something other than the cpu itself.
