separately reported on ATi R600 Crossfire sightings at the San Francisco launch.
AMD has publicly demonstrated a Barcelona system with a pair of 200W R600 cards
running in Crossfire mode which is capable of hitting one teraflop. The article
mentioned that researchers at Stanford were already writing supercomputing
applications for R600 and that R600 uses 320 multiply-accumulate (MAC) units
which could imply 40 vec4 per GPU and ~800MHz clock.

The reasons for R600 delay cited by Henri Richard: “R600 is doing very well and there’s a reason we’re going to launch it
when we’re going to launch it…I’ll take the blame. Launching Direct X 10
chipsets piecemeal was not welcome with AMD’s OEMs, and would not give the best
economic value for the firm, despite the clamour for new kit from hardcore
gamers and computing enthusiasts.” Our sources told us that X2900XTX will only
be available in limited quantities when launched.
