Samsung announced it has initiated mass production of its GDDR4 memory for graphics cards. It will be used on ATI's R580+ and NVIDIA's lineup for this fall will start using it as well.
The new GDDR4 memory has a data transfer rate around 2.4Gbps on a 32-bit bus. Samsung is shipping the new 80nm memory in 512MB configurations, which is likely configured in 16x32 layouts. Samsung also claims that this 2.4Gbps GDDR4 showed a 45% power savings when compared to 2.0Gbps GDD3. The reduction in power is clearly a welcomed trend.
"We're delighted that we'll be able to use GDDR4 from Samsung in our latest graphics cards,"."Samsung's timely introduction will increase the performance of our upcoming products and ultimately improve the gaming experience for our users,” claimed Joe Macri, ATI Senior Director of Engineering.
