AMD has updated its server processor roadmap with some new quad-core Opteron processors in the Opteron 8000-series, 2000-series and 1000-series.
Quad-core AMD Opteron 8000-series and 2000-series will initially use the Barcelona core. AMD will ship quad-core Opteron processors in SE, vanilla and HE models.
All Opteron 8000 and 2000-series processors include SE, vanilla and HE models share similar attributes. Each processor core will have access to its own 512KB of L2 cache for a combined total of 2MB. L3 cache is new to the Barcelona-core Opteron models -- a shared pool of 2MB of L3 cache is available to all four cores.
Barcelona-based Opteron 8000 and 2000-series Socket 1207 processors will have three HyperTransport links, though at launch the processor will only support HyperTransport 1.0 instead of the faster HyperTransport 3.0 bus. Other notable features of Barcelona quad-core processors include support for registered DDR2-667 and AMD-V technology. Quad-core Opteron 8000 and 2000-series processors will use the same socket F as its dual-core counterparts.
