Intel® E7505 Chipset Product Brief

The Intel® E7505 Chipset represents the next step in Intel workstation and server chipset technology. The latest in a family of volume enterprise chipsets, the Intel® E7505 chipset supports dual-processor platforms optimized for the Intel® Xeon® processor with 533 MHz system bus and Intel NetBurst® microarchitecture. The Intel® E7505 chipset design combines 533 MHz system bus with faster memory speed, next-generation AGP 8X graphics, and improved I/O bandwidth. Intel® Xeon® processor-based platforms with the Intel® E7505 Chipset deliver higher performance than previous Intel processor-based systems for mechanical design and analysis, digital content creation, and a variety of other demanding high-performance computing tasks.

Advanced Technology, Next-Generation Graphics, and I/O Flexibility
Intel® E7505 Chipset is comprised of three core components, which offer platform implementation flexibility to meet the demanding needs of dual-processor (DP) systems.

The Intel® E7505 Chipset Memory Controller Hub (MCH) is the central hub for all data passing through core system elements, such as: the dual Intel® Xeon® processors via the system bus interface; the memory subsystem through a dual-channel DDR memory interface; the graphics subsystem over an AGP 8X interface; I/O controller hubs via Intel® Hub Interface architecture. The E7505 chipset delivers the compelling performance of 4.3 GB/s of bandwidth across a 533 MHz system bus and up to 4.3 GB/s of bandwidth across two high-performance Double-Data-Rate (DDR) SDRAM memory channels. The MCH offers the designer the flexibility to support either unbuffered or registered memory. The high data throughput of these interfaces augment the direct-attach AGP 8X interface, which delivers up to 2.1 GB/s of graphics data.

The Intel® 82870P2 64-bit PCI/PCI-X Controller Hub 2 connects to the MCH through a point-to-point 16-bit Hub Interface connection. The Intel 82870P2 64-bit PCI/PCI-X controller hub 2 device extends over 1.0 GB/s of I/O bandwidth to two independent 64-bit PCI-X segments operating at 133/100/66 MHz. Each 64-bit PCI-X segment supports next-generation components such as Intel® Gigabit Ethernet adapters and multiple PCI-X or PCI slots.
