GDDR5 (Graphics Double Data Rate, version 5) is a type of graphics card memory. SDRAM refers to synchronous Dynamic random access memory, a term that is used to describe dynamic random access memory that has a synchronous interface SDRAM refers to synchronous Dynamic random access memory, a term that is used to describe dynamic random access memory that has a synchronous interface DDR SDRAM ( double data rate synchronous dynamic random access memory) is a class of memory Integrated circuit used in Computers It achieves nearly twice In Electronic engineering, DDR3 SDRAM or double-data-rate three Synchronous dynamic random access memory is a Random access memory Direct Rambus DRAM or DRDRAM (sometimes just called Rambus DRAM or RDRAM) is a type of synchronous dynamic RAM, designed by the Rambus XDR DRAM or extreme data rate Dynamic random access memory is a high-performance RAM interface and successor to the Rambus RDRAM it XDR2 DRAM is a type of Dynamic Random Access Memory that is offered by Rambus.

GDDR4 SDRAM (Graphics Double Data Rate version 4 is a type of Graphics card memory specified by the JEDEC Semiconductor Memory Standard Unlike its predecessors, GDDR5 has two parallel DQ links that provide doubled I/O throughput compared to GDDR3 and GDDR4. GDDR5 is currently in its design state, and products should be available as early as the first half of 2008. [1]
Qimonda, a spin-off of Infineon, has demonstrated and sampled GDDR5 [2], and released a white paper about the technologies behind GDDR5 [3]. Qimonda AG ( (pronounced "key-MON-duh" is a Memory company split out of Infineon Technologies AG on May 1 2006 to form the second Infineon Technologies AG () was founded in April 1999 when the Semiconductor operations of parent company Siemens AG, were spun off to form a separate On May 10, 2008, Qimonda announced volume production of 512 Mb GDDR5 modules rated at 3. 6 Gb/s (900MHz), 4. 0 Gb/s (1GHz), and 4. 5 Gb/s (1. 125GHz). [4]. Samsung has announced plans for the transition to GDDR5 by the beginning of 2008 [5]. The Samsung Group ( Korean:, Samsung Guerup) is South Korea 's largest company or Chaebol and the world's largest conglomerate
Hynix Semiconductor has introduced the industry's first 1 Gib GDDR5 memory. Hynix Semiconductor Inc of South Korea is a memory Semiconductor supplier of Dynamic random access memory ('DRAM' chips and Flash memory A gibibit (a contraction of gi ga bi nary digi' t') is a unit of Information or Computer storage, abbreviated as Gibit It supports a bandwidth of 20 GB/s on a 32-bit bus, which enables memory configurations of 1 GiB at 160 GB/s with only 8 circuits on a 256-bit bus. A gibibyte (a contraction of gi ga bi nary byte) is a unit of Information or Computer storage, abbreviated GiB. [6]
The Cooporation of Qimonda with AMD and ATI has been confirmed, and so the rumours about ATI Radeon 4-series graphics cards and GDDR-5
