Figure 4. Major components of Intel Xeon 5300 and 5400 Series processors Xeon 7300 and 7400 Series processors The Intel Xeon 7300 and 7400 Series processors use the Intel 7300 chipset, which features Dedicated High-Speed Interconnects (DHSI). DHSI is an independent, point-to-point interface between the chipset and each processor that allows full front-side-bus bandwidth to each processor (Figure 5). The point-to-point interface significantly reduces data traffic on the DHSI, providing lower latencies and greater available bandwidth. The chipset also features a 64-MB snoop filter that manages data coherence across processors, eliminating unnecessary snoops and boosting available bandwidth. Figure 5. Intel Xeon 7300 series processors with the Intel 7300 chipset and Dedicated High-Speed Interconnects Intel Xeon 7300 Series processors consist of two dual-core silicon chips on a single ceramic module, similar to the Xeon 5300 Series processors. Each pair of cores shares L2 cache; up to 4 MB of L2 cache can be allocated to one core. Intel Xeon 7400 Series processors consist of up to six cores that 6
