Most likely. The degree of the vulnerability is the question.

  GDDR4 is also affected?

    "GDDR4 is based on DDR3 SDRAM technology" The only real difference, afaict, is the speed is achieved with higher bitwidths (512bit vs 64bit) than regular SDRAM, so it is very likely to suffer the same vulnerabilities.
