• AGP3.0 interface
•
HyperTransport tunnel
Refer to the AMD-8151 graphics tunnel product brief and to the
Preliminary AMD-8151™
HyperTransport™ AGP3.0 Graphics Tunnel Data Sheet, order# 24888 for detailed specifications.
5.6.1.2 AMD-8131™ HyperTransport™ PCI-X
®
Tunnel
Targeting server and workstation applications, the AMD-8131™ HyperTransport™ PCI-X
®
tunnel provides high-speed PCI-X capability to platforms requiring high-performance I/O
expansion. The AMD-8131 I/O bus tunnel high-level feature-set includes the following:
•
Dual PCI-X interface (supporting 133-MHz, 100-Mhz, 66-MHz, and legacy-PCI speeds).
•
HyperTransport tunnel
•
APIC
Refer to the AMD-8131 I/O bus tunnel product brief and the
Preliminary AMD-8131™
HyperTransport™ PCI-X
®
Tunnel Data Sheet, order# 24637 for detailed specifications.
5.6.1.3 AMD-8111™ HyperTransport™ I/O Hub
The AMD-8111™ HyperTransport I/O hub integrates the system I/O functions into a single
component. The AMD-8111 I/O hub high-level feature-set includes the following:
•
HyperTransport interface
•
10/100 Ethernet
•
EIDE Controller, supporting up to ATA-133
•
AC‘97 Audio, USB
•
I/O buses: PCI, LPC, SMbus, APIC
Refer to the AMD-8111 chipset component product brief and the
AMD-8111™ HyperTransport™
I/O Hub Data Sheet, order# 24674 for detailed specifications.
5.6.2 Graphics and Storage
Workstations are typically more graphic-intensive than servers. A workstation is used by a single
user running applications that are more processor-intensive than a desktop. Programs such as CAD
systems, scientific analysis programs such as finite element analysis, etc., are very graphic
intensive. These types of applications require higher graphics capability than desktop systems.
Therefore, if you are building a workstation you would want to use a motherboard that supports an
AGP-8X graphics interface, such as is provided with the AMD-8151 HyperTransport AGP3.0
tunnel.
