As predicted, the Federal Trade Commission is suing Intel for, as they put it, "[engaging] in a deliberate campaign to hamstring competitive threats to its monopoly." This isn't going to end well for Intel.
Earlier this year, Intel was forced to pay a $1.45 billion fine by the EU, and last month they had to pay AMD a $1.25 billion settlement for anti-competitive practices. This new suit is for basically the same things.
The E.U.'s charges included paying computer makers to use Intel chips instead of AMD ones, and even threatening some companies if they went ahead and used AMD CPUs. The FTC notes that the public has been denied access to "potentially superior" chips as a result of the same bad practices. And it highlights what seems to be a particularly nasty one: Intel apparently designed compiler code so that it "deliberately stunted" the performance of the code when run on non-Intel CPUs, and then told the public the code simply worked better on Intel-made chips.
