GDDR4 Knocking the Door

Dom · May 5, 2004, 11:33 PM

"Sources with knowledge of the matter indicated there is a new memory technology in the works. Apparently, the tech will come alive by the end of the year and may be used commercially after that to replace the GDDR3.

The GDDR3 memory is expected to be widely used on high-end and mainstream graphics cards this year. Both NVIDIA and ATI now begin to use the GDDR3 with their latest graphics processors GeForce 6800 Ultra and RADEON X800-series.

The GDDR3 evolves from GDDR2, but will sport some pretty important differences. Firstly, GDDR3 makes use of a single-ended, unidirectional strobe that separates the reads and writes. GDDR2, by contrast, uses differential bi-directional strobes. Secondly, GDDR3 utilizes a “pseudo-open drain” interface technique that is based on voltage rather than current. This was done so that graphics chips can be compatible with DDR, GDDR2 and GDDR3. Like GDDR2, GDDR3 interface uses 1.8-Volt SSTL. Such memory is generally better suited for point-to-point links used on graphics cards and allows the GPU developers to reach the new performance and feature heights with their products."
