matthias  proposed the following answer:
glück auf ihr leit,

i  didn't try it own my own to compile yade with another compiler than
yade. the support of  our university hpc tried to use the intel compiler
but with no success at the moment.

 the difference  of intel and amd cpus, especially the FPUs, are as you
could see, really large see [1]

after some searching on the internet and speaking with hardware guys, i
came to the conclusion that amd invest not so much engineering to build
number crunchers. opterons are good and cost efficiency server cpus. and
some appliances in the top500 list use opterons. but the intel are
significant faster for FLOPs.

curiously, using a amd opteron cpu leads to more  numerical stable
results, at least on my experience [1]
