Hyper-Transport is a way for CPUs to exchange data directly rather than going through a memory controller, thus allowing limited resources (L1/2/3 cache) to be used more effectively. In particular, process migration causes fewer cache misses. Hyper-Threading is a way for a CPU to pretend to be two, thus causing the system to request/require more resources than are available. Hyper-Transport attempts to alleviate a bottleneck, while Hyper-Threading increases the load on an existing one. -- "If there's one thing we've established over the years, it's that the vast majority of our users don't have the slightest clue what's best for them in terms of package stability." -- Gentoo Developer Ciaran McCreesh -- gentoo-user@gentoo.org mailing list
