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.""

    speaking of amd.. I'm just about to build an Athlon 64 3800 (venice core) based system. I figure the new lines are a bit to pricy. Do any of you have some experiences with that cpu worth mentioning?

    Well that's not really the case. The slashmillionnaires would know the difference if they would acknowledge that the system is badly broken. If you were taco, raking in millions on this slow, lumbering, obsolete dinosaur, why would you change it? The revenue stream is only getting bigger. Why would you change it now? Progress? Hell, I've got my millions, why the hell do I need progress? Is it going to make my boat any bigger? Will it put more gold plating on my Ferrari? Fuck no, and therefore everything is working just perfectly.

    This post reminds me the time I caught the ferry over to Shelbyville. I needed a new heel for my shoe, so, I decided to go to Morganville, which is what they called Shelbyville in those days. So I tied an onion to my belt, which was the style at the time. Now, to take the ferry cost a nickel, and in those days, nickels had pictures of bumblebees on them. "Give me five bees for a quarter," you'd say.

    Now where were we? Oh yeah - the important thing was I had an onion on my belt, which was the style at the time. They didn't have white onions because of the war. The only thing you could get was those big yellow ones...

    It's "small penis". People who are good spellers scream out "Warning: I never get laid, I'm an uptight asshole and I like to correct others. Oh, and I have a small penis". Editors, this goes for you too.
