Rambus (Nasdaq: RMBS) touted its ramped-up computer chip memory interface known as XDR2 this week, heralding the high-speed interface as a tool for "unprecedented graphics capabilities" enabled through the new technology.

The latest version of its high-bandwidth XDR memory interface, XDR2, uses a DRAM core innovation known as microthreading and other enhanced technology to allow data rates of 8 GHz and higher, five times today's graphics DRAM memory, the Japanese company said.



Analysts indicated the graphics performance boost would have a wider impact than typical graphics technology improvements, such as graphics accelerators.

"This is certainly of a different class of specialization, and it's more of a broad brush improvement to graphics in what can be done in fine detail," Mercury Research President Dean McCarron told TechNewsWorld.

High Speed, High Performance

Rambus, which made the new interface available for licensing with products using the technology expected to ship by 2007, said XDR2 uses a number of new and enhanced technologies to boost data rates in the memory for computer and console graphics.

The company described the technologies:

  • Microthreading, which enables more bandwidth from DRAMs with reduced power consumption;
  • Adaptive timing, which is a speed enhancement through compensation for process, voltage and temperature variations;
  • Transmit equalization, an output circuit for minimizing the adverse effects of reflections and attenuation which has limited DRAM speed;
  • DRSL signaling, a signaling standard to reduce noise and signal loss.
"We are continually pushing interface technology forward to develop compelling and innovative solutions that meet our customers needs," said a statement from Rambus Vice President of Platform Solutions Laura Stark. "XDR2 is our latest iteration of the XDR DRAM architecture and will help 3D games and graphics-intensive applications realize the high performance potential that users demand."
 
this is way much better than ddr but it costs too much and i don't think it will be used in the socket 939 or socket 775 it will most probably be used in the new sockets if it will be used by amd or intel for main memory. but mostly it will be used for vgas because they require very high bandwith

sign me up for the first gfx card to feature this hot shit!
it will most likley when PS3 is released as this tech is featured in the PS3 and rambus have a habit of keeping new tech exclusive to the main company that has funded/driven development that tech has released its product using it (PS3 was the driving force behind XDR development)
