Hi.

I just have a new small laptop with N4200 proc. In the past I have one 
N3470.

With GCC , a couple of years ago,  I used the Linpack(Fortran) in single 
precision to have an idea of the proc capabilities.

I attached the Fortran source code. I downloaded GCC from this web page 
see http://www.equation.com/servlet/equation.cmd?fa=fortran

With the N3470, I was able to have more than 1 GigaFlops. (-O2, -O4...)  
and there was a difference when you changed the level of optimisation.

I just tried it  with the N4200, same result with different levels of 
optimisation, benchmark around 300 Megaflops !!!

I was just expecting something a little above the N3470 !

Clues/Hints?

Thanks in advance.

Best regards.

Jerome Huck.
