Bandwidth on line cards usually refers to how much throughput exists between the line card and the main switching fabric of the chassis. So for example on the 6500 switch a WS-6724-SFP has a 20Gb dedicated connection to the switch fabric.
The WS-6724-SFP supports 24 x 1Gb ports so there will be some contention on the ports. If you use only 20 of the 24 ports then in effect the blade is non-blocking as 20 ports = 20Gbps and the blade has a dedicated 20 Gbps connection to the switch fabric.
Some of the modules that go into a 6500 do not have dedicated connections to the switch fabric. Instead they use a shared connection to the switch fabric which could well lead to contention depending on the number of blades sharing this connection.
