GDDR

(Graphics DDR) Double data rate (DDR) memory that is used on graphics cards for fast rendering. Although GDDR is based on DDR memory technologies, the versions do not correspond numerically; for example, GDDR3 was based on DDR2 chips and so on. Each generation of GDDR includes different types of enhancements. See DDR and SDRAM.

AMD was the only company to make significant use of GDDR4 or HBM, after all.
10) In addition to the caps on royalties for its SDR and DDR DRAM technologies, Rambus's commitment to the EC also caps royalty rates for, among other things, DDR2, DDR3, GDDR3, and GDDR4 SDRAMs and memory controllers.
Under this agreement Rambus has granted NVIDIA a patent licence for certain memory controllers at a 1% royalty rate for SDR memory controllers and a 2% royalty rate for other memory controllers, including DDR, DDR2, DDR3, LPDDR, LPDDR2, GDDR2, GDDR3, GDDR4 and portions of GDDR5 memory controllers.
The ATI Mobility Radeon HD 4800 series graphics processors are the industry's first to support GDDR5 memory technology, providing nearly twice the memory bandwidth of GDDR3 and GDDR4, contributing to improvements in game play and performance.
Las tarjetas de video ATI Radeon HD 3850, con 256M8 de memoria GDDR3 tienen un precio inicial de 179 dolares y los ATI Radeon HD 3870 con 512M8 de memoria GDDR4 empiezan en 219 dolares.
ATi's standard specifications for X1950 XTX cards recommend the 512Mbytes of GDDR4 memory run at 1GHz.

Steeply tapered edges and lights embedded around the chassis make for one of the most eye-catching models out there, and with 4GB of GDDR4 RAM and 16GB of main memory, there's enough grunt under the hood to take on today's most demanding games.
2 Gb/s and data transmission speeds of > 1 Gb/s and can test GDDR3 and GDDR4 in addition to DDR3-SDRAM.
