The AIBs (Add-in Board partners) didn't see the real McCoy as this was a developer's card powered with GDDR3 memory only but it was enough to impress the present lads.
The GDDR4 version and the official launch is still scheduled for March time probably shortly before Cebit. The partners are happy with the performance and they are confident that the new baby can make G80 run for its pixels.
The first R600 with GDDR3 memory was a huge card, the biggest ever built but the GDDR4 version will end up a bit shorter. The first R600 was significantly longer than Nvidia's G80. ยต
