AMD reveals a reference design for the upcoming 16-core Interlagos server chip:
Upgradeability means that the current platforms that support AMD OpteronTM 4100/6100 Series processors should be the same as the platforms that will support the new AMD Opteron processors that are based on the “Bulldozer” core. (I say “should” because my lawyers always remind me that we make the processors, not the platforms so I can’t make statements for our partners….)
When we designed the current platform specifications we did so with “Bulldozer” in mind. This means that platforms can have the same BIOS, drivers, and associated software, which helps greatly reduce the tasks around managing platforms based on the 2 different processors.
