AMD 785G and Stream GPU Acceleration

The Radeon HD 4200 also has support for HDMI, DisplayPort (if integrated) and DVI. HDCP support is native to the Radeon HD 4200's video controller, so it's fully compatible with high-definition content played over Blu-ray discs. Within the AMD 785G are two independent display controllers, one digital (DVI/DP/HDMI) and one analog for displays. Depending on the manufacturers board-level implementation, the 785G will easily support dual monitors (one analog and one digital).

The integrated Radeon HD 4200 videocard on the AMD 785G chipset contains 40 stream processors and shares up to 512MB of installed system memory. The AMD 785G supports up to six PCI Express 2.0 x1 slots along with six PCI bus mastering slots, although it's up to the motherboard manufacturer to implement each expansion slot. There are generally six Serial ATA II ports and a single Ultra/133 IDE controller, coming from the AMD SB710 Southbridge.

Also integrated are twelve USB 2.0 ports, a Gigabit network MAC and a 7.1 channel High Definition audio controller.

ATI Stream GPU Acceleration

ATI Stream, like NVIDIA CUDA, is a way of accelerating desktop applications like Adobe Creative Suite 4, MediaShow Espresso and Microsoft Silverlight using a graphics processor instead of relying on just the CPU. There are certain intensive tasks that are easy to optimize for the massively parallel nature of an IGP like the Radeon HD 4200 that can cause even the fastest CPUs to stall. ATI has been working with developers like Adobe and Microsoft so that everyday programs can take advantage of a dedicated GPU in a desktop environment.

Adobe in particular has embraced GPU acceleration, and the latest version of its Creative Suite brings support for both NVIDIA Geforce and AMD Radeon GPUs. Hardware acceleration support in programs like Adobe Acrobat Reader and Photoshop can improve rendering performance and smoothness when navigating large PDF documents and images.

ATI Stream has added video transcoding technology that enables the Radeon HD 4200 IGP to accelerate video encoding. With the advent of video-capable portable media players like the iPhone, Sony PSP and Microsoft Zune, video encoding is an increasingly popular task even amongst mainstream and home users.

It also remains a very intensive task, as encoding or transcoding a movie ripped from DVD to play on the iPod can take hours depending on the video quality and length. Acceleration support is still quite limited at this point, with only certain codecs (H.264, MPEG2, VC1) and programs (Cyberlink Espresso, ATI Video Converter, Arcosoft Total Media Theatre) supported.

Let's go in for a closer look at the ASUS M4A785TD-V EVO motherboard next.
