GDDR-3 - Advantages of GDDR3 Over DDR2

Advantages of GDDR3 Over DDR2

• GDDR3s strobe signal unlike DDR2 SDRAM is unidirectional & single-ended (RDQS, WDQS). This means there is a separate read and write data strobe allowing for a quicker read to write ratio than DDR2.

• GDDR3 has a hardware reset capability allowing it to flush all data from memory and then start again.

• Lower voltage requirements leads to lower power requirements, and lower heat output.

• Higher clock frequencies, due to lower heat output, this is beneficial for increased throughput and more precise timings.
