single/double point accuracy?

[twist3d0n3]

hey all, read a bit about fermi where the article said it had impressive double point accuracy but not so with single point... i'm lost with this; can someone explain it for me please!

 

[twist3d0n3]

can you (or anyone else) elaborate on that for me?

i knew games used single precision, but i'm in the dark as to what it really means, and its relation to double precision

wow very concise explainations guys i'm starting to understand this a bit more now.

as has been said for supercomputers, they do massive calculations, which need double precision. from what i've read in the past, supercomputers use cpus, and thousands of them to deal with the massive throughput they're designed to.. am i right in thinking they don't use gpus?

thanks very much for the answers so far guys

so are things moving towards an equilibrium as such between workload on gpus and cpus with SCs?

wow they guy just asked what it was?

why did you write a massive post about how rubbish Nvidia is and all hail ATI?

it's still an interesting read

i started with a simple 'wut is it?' but as conversations go, they evolve, and it's interesting to see what effect it has on vendors' products
