Changes

It is not clear to me how the underlying hardware of GPU SIMD units of architectures with unified shader architecture is realized by different vendors, there is the concept of bit-sliced ALUs, there is the concpet concept of pipelined vector processors, there is the concept of SIMD units with fix bit-width ALUs. The white papers from different vendors leave room for speculation, the different instruction throughputs for higher precision and lower precision too, what is left to the programmer is to do microbenchmarking and make conlusions conclusions on their own.
