small in 5900 series:

High-performance 10 GbE switching — cut-through and nonblocking 
architecture delivers industry-leading low latency (~1 microsecond) and 
very demanding enterprise applications; the switch delivers a 1.28 Tbps 
switching capacity and 952.32 Mpps packet forwarding rate in addition to 
incorporating 9 MB of packet buffers

or big in 5920:

High-performance 10GbE switching — enables you to scale your server-edge 
10GbE ToR deployments with 24 high-density 10GbE ports delivered in a 
1RU design; delivers a 480 Gbps (357.12 Mpps) switching capacity in 
addition to incorporating 3.6 GB of packet buffers

Ultra-deep packet buffering — provides up to a 3.6 GB packet buffer to 
reduce network congestion at the I/O that is associated with the heavy 
use of server virtualization, as well as bursty multimedia, storage 
applications, and other critical services
