Nope. And it's also almost useless for science, since the 64bit IEEE
floating point is 10:1 times slower on top of the reality of bandwidth
limitations, and the 32bit support is ... not fully IEEE754 compliant.
Accuracy? What accuracy? So for 64bit, it's not the bet chip available,
faster chips are available (fab'd but not designed/sold by ... guess who).
It's not for Java, or science either. It's for *gasp* graphics on the
PS3! But that's good, people are willing to pay for graphics, but
science is a losing bet under the Bush inquisition.
nVidia and ATI are the only ones worried, and not very, all this is tech
old enough to not be under patent anymore.
