Samsung Electronics has shipped a graphics double data rate fourth generation (GDDR4), 256-Mbit device to major graphics card manufacturers for testing.
The GDDR4 memory device processes gaming and video images at 2.5-Gbits/s or 10-Gbytes/s, which is equal to transmitting 10 hours of DVD quality video. The fastest graphics memory to this point has been limited to a speed of 1.6-Gbits/s.
As games and video become increasingly high solution and require more content, graphics-DRAM data processing needs to improve at a similar pace. But when data travels between the graphics chip and the resident system, there's typically an inherent transmission delay that has limited the transmission speed.
To reach the 2.5-Gbits/s speed and eliminate transmission delays, the GDDR4 device employs two technologies -Data Bus Inversion (DBI) and Multi-Preamble. Collectively, the technologies help produce a transmission speed that is 56% faster than conventional graphics products, the company said.
