Introducing the AMD 780E
The AMD 780E (referred to in this document by its codenmae "RS780E") is an eighth generation Integrated Graphics
Processor (IGP) that integrates a DirectX
single chip. It supports AMD Athlon™ single-core and AMD Athlon X2 dual-core processors, AMD Sempron™
processors, and AMD Turion™ 64 X2 dual-core mobile technology. The RS780E integrates an ATI M72-based graphics
engine, dual display, an LVDS interface, internal or external TMDS, DisplayPort™ capability, and Northbridge
functionality in a single BGA package. This high level of integration and scalability enables manufacturers to offer
enthusiast level capabilities and performance while minimizing board space and system cost.
Robust and Flexible Core Logic Features
The RS780E combines graphics and system logic functions in a single chip using a 21mm body BGA package, reducing
overall solution area. For optimal system and graphics performance, the RS780E supports a high speed HyperTransport™
interface to the AMD processor, running at a data rate of up to 4.4GT/s and supporting both HT 1.0 and HT 3.0 protocols.
The RS780E is ideally suited for 64-bit operating systems, and supports platform configurations with greater than 4GB of
system memory. The rich PCI Express
Express external graphics controllers and up to six other PCI Express peripherals (up to seven when using only 8 lanes for
external graphics, or up to eight when not using external graphics), all supporting the PCI Express 2.0 standard with data
rates of up to 5.0GT/s. These capabilities are complemented by the advanced I/O features of AMD's SB710 Southbridge.
Best for Windows Vista
The RS780E delivers an unmatched Windows Vista
3.0 to a DirectX 10 graphics core, which provides the 3D rendering power needed to generate the Windows Vista desktop
even under the most demanding circumstances. The ATI M72-based graphics core employs a unified shader architecture
to deliver optimal 3D performance across the whole spectrum of 3D applications. This future-proof core ensures
compatibility with both current and upcoming 3D applications, and meets Windows Vista Premium Logo requirements
through 2008 and beyond.
Leading Multimedia Capabilities
The RS780E incorporates AMD's Unified Video Decoder (UVD) technology, which provides dedicated hardware decode
of the H.264, VC-1, and MPEG-2 video formats used in HD DVD and for Blu-ray disks. The RS780E also incorporates
the innovative ATI Avivo™* display architecture, providing users with visual quality which is second to none. Advanced
scaling and color correction capabilities, along with increased precision through the entire display pipeline, ensure an
optimal image on CRT monitors, LCD panels, and any other display device. Dual DisplayPort output capability provides
the ability to interface to the next generation of digital display devices. That is complemented by two integrated TMDS
interfaces, configurable to enable DVI/HDMI™ and support HDCP, allowing compatibility with even the most modern
high definition televisions without the additional cost of external components.
*Note: ATI Avivo™ is a technology platform that includes a broad set of capabilities offered by certain ATI Radeon™
products. Full enablement of some ATI Avivo™ capabilities may require complementary products.
Low Power Consumption and Industry Leading Power Management
The RS780E is manufactured using the power efficient nm technology, and it supports a whole range of industry
standards and new proprietary power management features. In addition to comprehensive support for the ACPI
specification, the exclusive ATI PowerPlay™ technology (enhanced with new adaptive frame buffer compression and ATI
PowerShift™ features) minimizes the RS780E's power consumption by adjusting graphics core performance and core
voltage to the task and usage environment. System power can be further reduced through the dedicated local frame buffer
interface supported by the RS780E. The integrated UVD dramatically reduces CPU loading and hence overall power
consumption during HD video playback.
