A $1,499 supercomputer on a card? That's what I thought when reading El Reg's report of AMD's Radeon R9 295X2 graphics card which is rated at 11.5 TFlop/s(*). It is water-cooled, contains 5632 stream processors, has 8 GB of DDR5 RAM, and runs at 1018MHz.
AMD's announcement claims it's "the world's fastest, period".
The $1,499 MSRP compares favorably to the $2,999 NVidia GTX Titan Z which is rated at 8 TFlop/s.
From a quick skim of the reviews (at: Hard OCP, Hot Hardware, and Tom's Hardware), it appears AMD has some work to do on its drivers to get the most out of this hardware. The twice-as-expensive NVidia Titan in many cases outperformed it (especially at lower resolutions). At higher resolutions (3840x2160 and 5760x1200) the R9 295x2 really started to shine.
For comparison, consider that this 500 watt, $1,499 card is rated better than the world's fastest supercomputer listed in the top 500 list of June 2001.

The more hardcore guys who post on hashcat.net's forum will probably have 4 of these running in one box within a week of the card's launch. Granted, it will take more than one power supply, but the kind of person who would bulk order these cards is also the same kind of person who has used multiple PSUs in the same rig before.

it would be useful for those of us want to scientific calculations, if they would run the benchmarks for computation for their rigs!! I would wager a few scientists would have a crack at replicating the best performing designs.
We might get the vendors to start optimizing for reproducible calculation, rather than marketing numbers...
