Both the cards, pictured in an exclusive photosession here at Computex, for the INQ used ultra high speed GDDR3 memory modules from Micron Technology.
A Micron official confirmed that it is GDDR3 running at 800MHz and giving a data rate of 1.6Gbps will be in full production in Q1 of 2004.
Here are the Nvidia pictures.
And here's a detail of the chip on this board.
Discussions indicated that samples of these boards may be available as early as November or December.
An interesting point about Micron GDDR3 is that it consumes significantly less power than previous memory types with a core requirement of 1.8 volts.
Here's a card where the chip is codenamed Viper.
Although the picture of the Nvidia engineering sample shows silk screening
where a heatsink design is shown, Micron suggests no extreme thermal cooling of these memory modules will be
necessary.
