GDDR

(Graphics Double Data Rate) GDDR is double data rate (DDR) memory specialized for fast rendering on graphics cards (GPUs). Introduced in 2000, GDDR is the primary graphics RAM in use today. GDDR is technically "GDDR SGRAM," superseding VRAM and WRAM. Although based on DDR memory, the versions do not correspond numerically. For example, GDDR3 was based on DDR2 chips; GDDR5 on DDR3 and so on. Each GDDR generation is faster and includes enhancements.

GDDR6
As of 2019, GDDR6 is the current version providing a 16 Gbps data rate instead of 13 Gbps for GDDR5X and twice that of GDDR5. GDDR6 also supports the same 32-byte read/write access as GDDR5. See DDR and GPU.

A new type of GDDR3 SDRAM is coming out which will run at 800 MHz; it currently is being used on high-speed graphic (hence the G) interface cards.
It wasn't unusual for AMD to be the only company to deploy HBM; AMD and Nvidia had split similarly over the use of GDDR4 a decade ago, with AMD adopting the technology and Nvidia choosing to stick with GDDR3. Nvidia's decision to use a stopgap GDDR5X raised a few eyebrows, but HBM2 still seemed to be the better long-term technology, especially when Nvidia deployed it first for its high-end GPUs and AMD was following suit with Vega.
The graphics clock runs at 602 MHz, the processor clock at 1296 MHz, it comes with 1024 MB of memory in the standard configuration, having an effective clock of 1107 MHz, a 512-bit gDDR3 memory interface width and 141.7 GB/sec memory bandwidth.
