share a 16 MB L3 cache (Figure 6). Intel Xeon 7300 and 7400 Series processors are available on the ProLiant BL680 G5 server blade. Figure 6. Major components of Intel Xeon 7300 and 7400 Series processors AMD Opteron™ quad-core processors Third generation, quad-core AMD Opteron 2300 and 8300 Series processors feature HyperTransport™ technology, which provides a direct, scalable bandwidth interconnect between the processor, the I/O subsystem, and the chipset. Each quad-core processor operates at speeds of up to 3.1 GHz, has 512 KB of L2 cache memory, and shares a total of 6 MB of L3 cache (Figure 7). The processor has an integrated memory controller that supports PC2-6400 (DDR2-800) DIMMs. The AMD Direct Connect™ architecture replaces the FSB with direct communication links between each CPU, between CPU and I/O, and between CPU and memory. 4 Quad-core AMD Opteron 2300 and 8300 Series processors feature AMD Dual Dynamic Power Management™. This feature powers the processor core and memory controller voltage planes independently and delivers increased performance and improved power management. Figure 7.
