BTW, you can usually answer these type of questions by searching through the device datasheets, and it you're not used to doing that, it's a worthwhile skill to develop, especially helpful when comparing different devices.
In any case, your sup7e has a fabric bandwidth of 848 Gbps and 250 Mpps. That sup, with the +E chassis supports 48 Gbps to line cards. However, your 46xx line cards only support 24 Gbps to the fabric.
Your 3750s are the original architecture. They all have a 32 Gbps fabric, and a maximum forwarding rate of 38.7 Mpps. (24 gig port, or 48 FE port models may show a lower max PPS because all their ports, together, have a lessor PPS need.) Original architecture 3750s have StackWise ports, noted as 32 Gbps (which I believe are dual 8 Gbps [duplex]). Also note, with StackWise, all traffic between 3750 ports is placed on the stack ring, even between two ports on the same stack member.
