GDDR6 provides higher densities than previous-generation graphics memory. It doubles the bandwidth (12–16 Gb/s) of GDDR5 while remaining on the traditional discrete package technology (FBGA). GDDR6 has the same low external voltage (1.35V) as GDDR5X but is based on a dual-channel architecture instead of GDDR5X’s single-channel architecture, which enables a huge performance increase while still providing backward compatibility to GDDR5.
GDDR6 extends the lifespan of the graphics card ecosystem in the follow ways:
- Uses a cost-efficient, mature assembly process on conventional equipment, resulting in high product reliability and fast time to market
- Uses a similar BOM structure to GDDR5 and GDDR5X
- Follows successful path of PCB assembly while enabling system data rates up to 1 TB/s
