For a number of years it also produced code that ran much slower on AMD processors. The Intel compiler is used to compile a bunch of benchmark tools that tech sites use in their reviews, so this (in conjunction with certain other brutal strategies on Intel's part to pressure and bribe vendors into selling Intel only) basically contributed to the destruction of AMD's market share in the early-to-mid 2000s.

It still does, as far as I'm aware. The current optimisation notice is <https://software.intel.com/en-us/articles/optimization-notice/> https://software.intel.com/en-us/articles/optimization-notic.... For those who don't want to click a link or are using screen-readers (because yay textual content as an image!): > Intel's compilers may or may not optimize to the same degree for non-Intel microprocessors for optimizations that are not unique to Intel microprocessors. These optimizations include SSE2, SSE3, and SSSE3 instruction sets and other optimizations. Intel does not guarantee the availability, functionality, or effectiveness of any optimization on microprocessors not manufactured by Intel. Microprocessor-dependent optimizations in this product are intended for use with Intel microprocessors. Certain optimizations not specific to Intel microarchitecture are reserved for Intel microprocessors. Please refer to the applicable product User and Reference Guides for more information regarding the specific instruction sets covered by this notice.

I remember the dread I felt when I read that news, but it went away real quick .. I'm not even sure it was the whole story. I expected more backlash against intel for rigging a whole market that way.

  There's an excellent summary on Reddit [1]. Apparently there's a court order, as part of a settlement with the FTC [2], intended to stop the cheating, but apparently as of 2010, Intel still wasn't honouring it.
