Transfer Rate Maximum rate of transfer of information to or from a memory device.
Increasing the computational power without a corresponding increase in the bandwidth of data to memory can create a serious bottleneck.
MFLOPS are easy---Bandwidth is difficult
One processor of a CRAY Y-MP can transfer 500 Mwords/sec.
Complete system a total of 4 Gwords/sec as the peak memory bandwidth.
