Editing HyperTransport (section)

=== Front-side bus replacement ===
The primary use for HyperTransport is to replace the Intel-defined [[front-side bus]], which is different for every type of Intel processor.  For instance, a [[Pentium compatible processor|Pentium]] cannot be plugged into a [[PCI Express]] bus directly, but must first go through an adapter to expand the system. The proprietary front-side bus must connect through adapters for the various standard buses, like [[Accelerated Graphics Port|AGP]] or PCI Express. These are typically included in the respective controller functions, namely the ''[[Northbridge (computing)|northbridge]]'' and ''[[Southbridge (computing)|southbridge]]''.

In contrast, HyperTransport is an open specification, published by a multi-company consortium. A single HyperTransport adapter chip will work with a wide spectrum of HyperTransport enabled microprocessors.

[[AMD]] used HyperTransport to replace the [[front-side bus]] <!-- There was a reason the article was titled "Front side bus" (now Front-side bus): it is correct.  Just because some phrase has an acronym does not mean its constituent words should be capitalized. --> in their [[Opteron]], [[Athlon 64]], [[Athlon II]], [[Sempron 64]], [[Turion 64]], [[Phenom (processor)|Phenom]], [[Phenom II]] and [[Bulldozer (microarchitecture)|FX]] families of microprocessors.
