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. ... By design, the 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.""

This was listed in the anti-trust lawsuit and discussed already.

It's called good business

so what if intel compiliers do that? it's the INTEL compilier. first of all, of course code compiled on the INTEL compilier is going to run fastest on intel chips b/c intel knows the inner workings of their chips better than they'd know AMDs. why spend all the money for R&D to learn AMDs chips to make a free compiler who's sole purpose in life is speed up processes on intel chips.

nobody is stopping AMD from making a free compiler that does the same thing.

STFU AMD, and ante up.

Before we damn Intel

Isn't it possible they just know their own product better and thus can create a better compiler for it?

Oh brother

[cheezedawg]

Another example of AMD trying to win in the marketplace through whining. There is nothing preventing AMD from releasing their own compiler. Instead they are just bitching about Intel again.

Intel doesn't come close to a monopoly in the compiler market, so I fail to see what this has to do with the antitrust suit.

[bemenaker]

Quit being so god damn picky, so it was in AAC not MP3 the point is still valid and accurate nitpicky dumbass moron. Yes flamebait was intentional and it was deserved for the sheer stupidity.

socialist AMD

[Sebastopol]

Yes, Intel should spend its R&D budget developing an optimized compiler for AMD.

I'm glad we have a bunch of liberal socialists supporting AMD.

Excuse me while I go listen to Rush's "The Trees" and read some Ayn Rand.

My God! I mean, you have to use a compiler switch to generate optimized code?! Outrageous! P-o-s-i-t-i-v-e-l-y o-u-t-r-a-g-e-o-u-s!!! I mean, all these years I used GCC and I never had to use any switches to generate the fastest code possible. We're suing the bastards!!
