PCI-X = 64bit Bus x 133MHz = 1,064,000,000bytes/sec (~1.014GB/sec)
64bit PCI = 64bit Bus x 66MHz = 528,000,000bytes/sec (~503MB/sec)
32bit PCI = 32bit Bus x 33MHz = 132,000,000bytes/sec (~126MB/sec)
1Gbit = 125,000,000bytes/sec (~119MB/sec) MAX, you never really get it.
Even full duplex (~238MB/sec) you still only half saturate the PCI bus.
In reality you are lucky to get ~3/4 of the actual speed and then there
is the rarity of actually fully saturating both incoming and outgoing
ports.
HTH!
