Nvidia is planning to have its 55nm GT200 cards in retail / etail by early December. The company has started shipping these chips a few weeks ago and evaluation boards have been manufactured a few weeks ago, too.
Now the wait is purely logistic as it takes a long time to
get the cards from Taiwan and China back to the western world. We learned that
new cards should overclock better, but the first wave will be clocked at the
same speeds as Geforce GTX 260, 216 Shaders and we suspect that GTX 280 cards
will also get a new 55nm chip.
The new chip should have drastically lower power consumption
and it should overclock higher and luckily we won’t have to wait much more to
find that out.
