Figure 2-1: Single-Core AMD Opteron Processor Architecture (Stepping E and earlier generations)
The Sun Fire X4100 M2 and X4200 M2 servers support AMD Opteron 2200 Series processors (aka stepping F). From the start, AMD64
processors were designed for multi-core architecture the core being connected to IO via a crossbar/SRI. Dual-core AMD Opteron pro-
cessors have unique instances of L1 cache (I-cache and D-cache) and L2 cache for each CPU core. Features of the Dual-Core AMD
Opteron processor include:
• 1207-pin (socket F) package compatitible with next generation multi-core AMD Opteron processor
• One die with 2 CPU cores
• Individual L1 Instruction cache per CPU core
• Individual L1 Data cache per CPU core
• Individual 1 MB L2 cache per CPU core
• Shared memory controller and HyperTransport interconnects for 2 cores
• Fully utilized memory and HyperTransport bandwidths
