cuda and double-precision floating-point arithmetics

 原文  2012-03-26 16:28:41  9   2    cuda/ gpu/ gpu-programming

Question

this is what i found: " Cores perform only single-precision floating-point arithmetics. There is 1 double-precision floating-point unit. "

is this true for all compute capabilities (versions) ?

Single and double precision floating point accuracy and performance has continuously evolved and is different for each of the compute capabilities.
