STREAM "32-bit" results


This is the "32-bit" set of STREAM benchmark results.

This set includes only 32-bit results --- i.e. results based on either 32-bit data elements or 32-bit arithmetic. Many of the 64-bit results actually move data in 32-bit chunks, but as long as the operands and operations are 64-bit, those cases remain in the other tables.

All results are in MB/s --- 1 MB=10^6 B, *not* 2^20 B
