It looks as if ATI might be the first company to embrace DDR5 memory. We are not sure if Nvidia will have support for DDR5 in its next generation, but ATI might be the first to market.

GDDR5 obviously offers better memory bandwidth, and traditionally new memory is faster and cooler than the previous generation.

Sample production of GDDR5 has already started, and the graphics memory chip manufacturers are playing with it; Quimmonda is being one of the outspoken about it.
