Here's a quicky for you, from the assorted Computex coverage around the web. Anandtech has photos
of Nvidia G70, and it looks... well, who knows?
The card is single slot, and has a funky Nvidia cutout on the heatink. There's an SLI connector on the top, for the one person that doubted it would have SLI. There are a heck of a lot of mosfets at the back of the card, which rather suggest that it requires a) a lot of power and b) a lot of power regulation. However, it does appear to run off a single PCI graphics power connector.
The cooler, technically, looks about the same as the single-slot cooler on the 6800GT.
Meanwhile, the Inquirer
is reporting that R520 will have 32-pipes built in, and will either have 24 or the full 32 enabled at launch, depending on how fast G70 is. If ATI can beat G70 with 24 pipes, then that's what they'll ship at - otherwise they face the problem of very small yields of 32 pipe chips.
However, that doesn't rule out the possibility that Nvidia might have an 'Ultra' part up their sleeve.
