AMD vs Intel, Intel Raided
by Steve Gibson, Jul 12, 2005 10:47am PDTSo the AMD vs Intel lawsuit is indeed raging on and the allegations from AMD have really begun to pile up. One of the most recent ones to come to light is that the compiler distributed by Intel actually compiles differently when an AMD processor is detected. Intentionally making applications slower and more prone to crashing. Here's the full PDF (Thanks /.) if you're feeling all lawyer like.
"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.""Update: Looks like some Intel offices just got raided!

Does this whole suit seem like a big marketing plan to anyone else? I mean read through the document, it reads like a novel not a court filing. AMD wants the average person to be able to understand it and goes through the process of painting Intel as the big-bad-evil corportation.
Now, I'm not saying Intel didn't do anything of these things, but where's the DOJ on this matter? The Justice Dept. went after Microsoft for anti-trust, but they don't seem to be making a big deal out of Intel. Also, Japan's FTC basically gave Intel a slap on the wrist in their findings (no monetary fine). They basically said "Stop it, bad Intel."

AMD licenses MMX, SSE, SSE2 from Intel. However, Intel's compiler will not let these instructions run on an AMD cpu with Intel's compiler.
Intel's compiler sets memcpy to move things 8 bits at a time unless an Intel Pentium 4 is in use, then it does it 32 bits at a time. The current version even screws over the Pentium 3. Why? Perhaps to make the P4 look good at all costs.
Setting the compiler to optimized, then editing the GenuineIntel string to AuthenticAMD in the executable causes the optimizations to run on AMD Athlon XP/Athlon 64 processors with no problems, and with all the benefits.
In short, AMD makes superior processors and Intel has been trying to screw them for a while.
Oh yeah, what kind of programs are compiled with Intel's compiler?
- Games
- Scientific Applications
- Benchmarks
i.e. where it matters most.
Your run-of-the-mill MS Office and GATOR uses the MS Visual C++ usually.

I think Intel should be sanctioned for the things they have done, imagine if for instance the gas companies made a deal with Ford, so that non-Ford vehicals that used their gas would get corroded engines from using it. That is basically what Intel did with the compiler.

Anyone using Intel at this point for games is either ignorant or completely in denial, no I am not going to post links to benches just like I won't post links to articles proving the world is round. Every single hardware site on the web has had the same findings for over a year now $200 AMD proccessors destroying $1000 Intel proccessors in games. There is no logic at all to buying an Intel proccessor.
"AMD is so buddy though!" LOL, this is 2005 not 1995, I haven't had a single blue screen since I upgraded to XP on multile AMD chips and chipsets both VIA and NForce except for when I was overclocked way too high.

I think AMD hasn't got a fuckin leg to stand on when they say the compiler is designed to slow applications down or even crash when used on AMD processors. Thats a load of crap, they should prove it first, which I don't think is going to happen, just a pile of poopoo heresay.
My opinion ? If AMD wins this case, I will have lost all respect for them as it was totally uncalled for. If they lose ? Intel will probably fire back and sue them for every damn penny they have due to hardship, drops in stock, etc.
AMD could potentially be digging themselves a nice deep hole right now, they better fill it in one way or another.

It detects whether the processor is a "Genuine Intel" and a "Pentium 4". If it doesn't then it does not use the standard extensions MMX, SSE, SSE2, SSE3. It will emulate them instead. So if your have a AMD it will not use those extensions. If your own a Pentium 3 or less it wont use them either.
This is complier optimization effectively slows down AMD and non-pentium 4 processors.

"In April 2003, AMD introduced its Opteron microprocessor, the first microprocessor to take
x86 computing from 32 bits to 64 bits – an advance that allows computer applications to
address exponentially more memory, thereby increasing performance and enabling features not
possible with just 32 bits. Unlike Intel’s 64-bit architecture of the time (Itanium), the AMD
Opteron – as well as its subsequently-introduced desktop cousin, the AMD Athlon64 – offers
backward compatibility, allowing PC users to continue using 32-bit software as, over time,
they upgrade their hardware. Bested in a technology duel over which it long claimed
leadership, Intel increased exploitation of its market power to pressure customers to refrain
from migrating to AMD’s superior, lower-cost microprocessors."
