US FTC Sues Intel For Anti-Competitive Practices
Vigile writes "And here Intel was about to get out of 2009 with only a modestly embarrassing year. While Intel and AMD settled their own antitrust and patent lawsuits in November, the FTC didn't think that was good enough and has decided to sue Intel for anti-competitive practices. While the suits in Europe and in the US civil courts have hurt Intel's pocketbook and its reputation, the FTC lawsuit could very likely be the most damaging towards the company's ability to practice business as they see fit. The official hearing is set for September of 2010 but we will likely hear news filtering out about the evidence and charges well before that. One interesting charge that has already arisen: that Intel systematically changed its widely-used compiler to stunt the performance of competing processors."
The compiler identified the CPU and changed it's behavior to be unoptimized if not the "golden" part. This falsely caused publicly used benchmarks to show competitors parts to be slower.

I like the complaint about the compiler. After all, Intel should be required to optimize their compiler for their competitor. To each according to his need...
The allegation is their compiler can, but deliberately does NOT, apply optimization to code if it detects the processor is AMD.
This is analogous to video game consoles refusing to use generic memory sticks or hard drives. Of course, intel will try to claim it's more like trying to attach a sata drive to an IDE port, but we all know the instruction sets for X86 are standard across both chips.
VLC FOR MAC IS DYING! IF YOU DEVELOP, PLEASE SAVE IT!!
because of the hardware differences, and didn't put in a switch for AMD, well, who says they had to,
Apparently, the government. You see it wasn't a case where they simply didn't setup their compiler to optimize for AMD's parts. They explicitly made it run worse if you were running non-Intel hardware. Normally that would just be incredibly sleezy, but Intel is quite possibly in a monopoly position, which makes some behavior that's normally just sleezy illegal instead.

Let's break it down. For instructions sets like SSSE3, SSE4, etc. Intel designed bits to identify if these instructions are supported. All competitors comply with these bits. What they did do is: if the part isn't identified as "Genuine INTEL" the compiler stopped code optimizations. This is a provable fact.

Are you fucking kidding me? Intel didn't just "not test" it with AMD's stuff, they went out of their way to make sure it wouldn't work on it. And if AMD's processors didn't run x86 code properly a whole lot more people would notice then just the ones using Intel's compilers. Do you even have any clue how a compiler works?
You are saying that what Intel did with their compiler is perfectly legitimate. I don't see how you can spin that as anything but defending them.
And that issue is long-settled: they are not allowed control over their own products to they extent they can harm competition in the market as they please. The only possible "issue" is whether their actions did or did not illegally harm competition.
Okay, now I'm definitely sure you don't understand the slightest bit about the technology involved. The CPU is already "unbundled" from everything to the maximum extent technically possible. They cannot "unbundle" it any further. The code would've run just fine on AMD's chips precisely because it is "unbundled" and is an interchangeable piece of hardware with multiple independent implementations. Intel has absolutely no defense here, certainly not on technical grounds, and you're just making yourself look like a fool trying to argue for them.
No it was much worse than that. There is a CPU instruction named CPUID which tells you the processor family, manufacturer, and has a set of feature flags saying which extensions (e.g. SSE, SSE 2, 3DNow) that particular processor supports. Intel's compiler enabled SSE optimizations only if the processor manufacturer string was "GenuineIntel" and the processor family number was high enough, instead of checking in the flags vector if the processor supported SSE.
