Brussels - The European Union’s top antitrust regulator has charged that Intel tried to use its huge market share to push smaller rival Advanced Micro Devices (AMD) out of the central processing unit business.

The two companies make all the chips at the processing heart of the world’s one billion personal computers and servers, but Intel has about 80 percent of the business.

The European Commission, in its latest antitrust case to involve a technology giant, alleged Intel broke EU law “with the aim of excluding its main rival, AMD, from the x86 computer processing units (CPU) market.” X86 is the designation for the chips.
