PCI 1x isn't necessarily the main limitation for a gigabit Ethernet connection.
PCI 1x isn't necessarily the main limitation for a gigabit Ethernet connection.
Gigabit ethernet delivers 1 gigabit per second or 125 megabytes per second on a single fiber lane. Each PCI-E lane operates at different speeds: PCI-E 1.0 provides 250 MB/s, PCI-E 2.0 reaches 500 MB/s, PCI-E 3.0 offers 985 MB/s, and PCI-E 4.0 is double that at 2 x 985 MB/s. Even the slowest PCI-E x1 slot would surpass the bandwidth of a typical gigabit network card. Back then, PCI was considered adequate since standard 32-bit PCI at 33 MHz could handle up to 133 MB/s across all devices, easily supporting 110-120 MB/s.
gigabyte and gigabit also rely on PCIe gen PCIE 4.0 offering around 2 gigabytes per second in x1 lane
It's 1 gigabit per second or 1 billion bits or about 125 GB/s. That's roughly 125 MB/s or 119.2 MiB/s. Numbers can be tricky.
My reason is the coffee isn't ready yet. Please return in about an hour or so...or else I might lose it.
