2004-08-12 GDDR-3
New high-speed memory standard for graphics based on DDR-II. To start at around 500 MHz with 1Gb/s/pin bandwidth. Runs on 1.8 V.
The Register: "GDDR 3 runs at up to around 1.5 times the speed of GDDR 2 yet consumes half the power, thanks to a lower operating voltage: 1.8V compared to 2.5V. GDDR 3 provides an aggregate bandwidth of 6.4GBps per device, thanks to a 1.6Gbps per pin data rate. It clocks between 600MHz and 800MHz."
