GDDR5 technology also holds a number of benefits for stream processing in general purpose GPU applications. The increased bandwidth will "greatly benefit certain classes of stream computations" and new error detection mechanisms in GDDR5 can also help "increase the accuracy of calculations by indentifying errors and re-issuing commands to get valid data," AMD said.
