This is the physical bus between the processor and the chipset. It has to exist unless you get a processor built into the chipset itself. *Most* processors get to memory by going through the FSB to the north bridge of the chipset, and then from the chipset to the memory chips. Historically this has been one of the bottlenecks in getting better system performance. *Some* processors can actually connect memory directly to the processor on a private memory bus.

Well, this may be partially true, in the sense that AMD has added a lot more bandwidth on their buses in recent processors so the bottlenexk is less of an issue than on most Intel systems today, but ALL systems have a memory bottleneck, in the sense that it's not unlimited bandwidth. It just may be less of a problem than other parts of the system. > > I'm currently researching a piece on AMD64 for Sound on Sound, so I'd > be glad to hear about any real-world experiences.

The eMachines M6805 laptop have been an excellent performer under Windows XP running Pro Tools, but eMachines tells me they've stopped making it. Very little in-depth data (yet) under Linux though. Ivica is working with the M6807 I think. The entry level price on these AMD-64 machines is phenominal - HP has one at only a few dollars over $1K. > > Cheers > > Daniel > >
