Each range of 8 ports (1-8, 9-16, 17-24, 25-32, 33-40, 41-48) has an ASIC.
 Each ASIC can do a max of 1 Gb in each direction.  If all ports on a group
of 8 were to upload and download, their combined throughput would be 1 Gb
upload and 1 Gb download.  If all ports on the card were to upload and
download at the same time, the combined throughput would be 6 Gb upload and
6 Gb download (1 Gb per group with 6 groups).

I've also heard that there's a 1Gbps limit on EtherChannels - apparently EtherChannel packets have to be sent to each ASIC, so building any EtherChannels on the card could be detrimental.
