      What is real difference in network performance (in real life complicated environment, i.e. a lot of packets different sizes, etc...) between this one

      Original Intel EXPI9404PTG2L20 EXPI9404PT PRO/1000 PT Quad Port Server Adapter
      Intel 82571GB
      Launch Date Q1'07
      PCIe 1.0a
      Specification
      Specification 2

      and this one

      Fujitsu PRO/1000 PT Quad Port Gigabit Network Card PCI-E D2745-A11 low profile
      Intel 82580eB
      Launch Date Q4'10 (?)
      PCIe 2.0
      Specification

      ?

      From engineering point of view I also see a less electronic components on FUJITSU branded version. (3 Year difference in launch date,- big gap for nowadays....)

          You are basically looking at this:
          https://www.intel.co.uk/content/www/uk/en/products/compare.html?productIds=41280,20720

          PCIe 1 vs 2

          Some virtualisation support in the 82580.

          But 82571 is an em(4) NIC but 82580 is an igb(4) muti-queue NIC. If you have multiple CPU cores that is going to load them far more efficiently.

          I'd get the newer card given a choice.

            Dear Steve!

            Thank You so much for detailed answering.

            I keep in memory about 82580 igb(4) multi-Queue, but anyway asking people’s with better knowledge. ;)
