Diamond fire 1000 has two advantage over the Bvision one is the AGP the other is it has 125@Mhz Ultra Low Latency SGRAM.
Bvision is fitted with 100Mhz Fujitsu or Micron Sgram as standard. I do believe there is one other type of sgram fitted to card.
Permedia 2 works better with faster sgram. The difference between 100Mhz and 125Mhz sgram is big,and the difference between 125Mhz and 143Mhz sgram is smaller when using permedia 2.
How well the Permedia 2 overclocks depends on the sgram fitted and other factors which I will not discuss.
It will be interesting to see what the timing parameters are and is it taking advantage of Low Latency SGRAM.
