AMD To Employ GDDR5 Into Next Generation ATI Radeon Solutions
AMD today announced the first commercial implementation of Graphics Double Data Rate, version 5 (GDDR5) memory in its next generation of ATI Radeon graphics card products. AMD is working with a number of leading memory providers, including Samsung, Hynix and Qimonda, to bring GDDR5 to market. The higher data rates supported by GDDR5 – up to 5x that of GDDR3 and 4x that of GDDR4 – enable more bandwidth over a narrower memory interface, which can translate into improved performance delivered from smaller, more cost-effective chips.
In addition to the potential for improved gaming and PC application performance, GDDR5 also holds a number of benefits for stream processing, where GPUs are applied to address complex, massively parallel calculations. Such calculations are prevalent in high-performance computing, financial and academic segments among others. AMD expects that the increased bandwidth of GDDR5 will greatly benefit certain classes of stream computations.
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. This capability is a level of reliability not available with other GDDR-based memory solutions today.
