Slashdot reports "AMD Alleges Intel Compilers Create Slower AMD Code"
"
edxwelch writes "In AMD's recient anti-trust
lawsuit
AMD have examined the Intel compiler and found that it deliberatly runs code slower when it detects that the processor is an AMD.
"To achieve this, Intel designed the compiler to compile code
along several alternate code paths.
code paths were not created equally. If the program detects a "Genuine Intel" microprocessor,
it executes a fully optimized code path and operates with the maximum efficiency. However,
if the program detects an "Authentic AMD" microprocessor, it executes a different code path
that will degrade the program's performance or cause it to crash.""

Could this be true? I just bought an AMD machine... Could Intel really be this unscrupulous or this stupid?

I don't think many applications are built with the Intel compiler (though I could be wrong) so most likely it won't affect you. It could affect benchmarks, though.
my friend compared AMD complaining about intel not writting a faster code for them as to complaining about your neighbor's coffee being better. he thinks that if AMD wants special optimising code, they should just write it themselves and not expect intel to do extra work for them...
I guess that kinda makes sense, no?
