a. PCIe 4.0 x16 bus can supply a maximum bandwidth of 256Gb/s (=16 *16GT/s, including overhead),
and can support 200Gb/s when both network ports of the card run at 100Gb/s.
b. The Gen4.0 cards have been tested and certified with PCIe 3.0 servers. PCIe 4.0 interface will be
tested when servers with Gen 4.0 support become available.
For more detailed information see Specifications.
