Intel® E7205 Chipset Product Brief

The Intel® E7205 Chipset represents the next step in entry workstation chipset technology for the Inte® Pentium® 4 processor. The Intel® E7205 chipset design provides a compelling transition to next-generation workstation-class technologies by delivering support for Hyper-Threading Technology along with maximized system bus, memory, and graphics bandwidth.

Advanced Technology and Next-Generation Graphics

The E7205 chipset combines two core components which were designed, optimized, and validated for the Pentium 4 processor with Intel NetBurst® microarchitecture.

The E7205 Chipset Memory Controller Hub (MCH) is the central hub for all data passing through core system elements, such as: the Pentium 4 processor via the system bus interface; the memory subsystem through a dual-channel memory interface; the graphics subsystem over an AGP 8 interface; and the I/O controller hub via Intel® Hub Interface architecture. The E7205 chipset delivers the performance of 4.3 GB/s of bandwidth across the 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 high data throughput of these interfaces augment the direct attach AGP 8 interface, which enables up to 2.1 GB/s of graphics data. Connectivity to advanced networking components and peripherals is provided via the Intel® 82801DB I/O Controller Hub (Intel® ICH4). Also, the E7205 chipset supports Hyper-Threading Technology. Together, these features deliver a balanced, high throughput system for demanding workstation-class applications.

The Intel 82801DB I/O Controller Hub (ICH4) connects to the MCH through a point-to-point Hub Interface 1.5 connection. The Intel® ICH4 provides 32-bit PCI connectivity to Intel® Gigabit Ethernet adapters. Additionally, the ICH4 includes integration for up to six ports of Hi-Speed USB 2.0; offering greater bandwidth for I/O-intensive peripherals. New power management and audio capabilities are also incorporated into this component.
