CHATSWORTH, CA —April 15, 2008— Diamond Multimedia (http://www.diamondmm.com),
a leading manufacturer of PC graphics cards, sound cards and communications
products, introduced today the 1 gigabyte, overclocked version of the ATI Radeon™ HD
3870 graphics card. This card offers maximum speed and power at an incredible value.
Utilizing 55nm technology, this card runs cool and quiet.

Diamond was the first AIB for AMD to launch a consumer based 1GB card with the HD
2900 XT. Today, we stand alone to again to be the first AIB to offer the HD 3870 1GB.
The performance itself matches against Nvidia new line of 9xxx series, as well against
the HD 3870 X2.

The HD 3870 is a dual slot card, PCIE 2.0, with 1024MB of DDR3 memory and an
overclocked speed of 825 MHz. The memory speed is 900 MHz. As with the original
HD 3870, the 1 gigabyte version is designed with 320 stream processors and plug-andplay
ATI CrossFireX™ upgradeability with up to quad-GPU support.

The Radeon HD 3870 will blow users away with life-like graphics from the latest
Microsoft® DirectX® 10.1 games and stunning 3D graphics and shading effects.
Experience the best of Windows Vista and bump up the performance of the Windows
Aero™ graphical interface.

Uncompromising HD video is delivered via ATI Avivo™ display technology. The latest
Blu-ray and HD DVD movies play smoothly at full 1080p with a dedicated hardware
video decoder that leaves your CPU unbound to do other tasks. Enjoy digital content
with HDMI and built in 5.1 surround sound.

All Diamond video cards carry the Diamond guarantee of quality assurance. Unlike
many cards that are simply first to market, Diamond carefully tests and retests every
new model for its ratio of performance to reliability. Diamond is legendary in the PC
video card business for its less than 1 percent return rate versus an industry average of
approximately 10 percent. Diamond cards use superior connectors, cables and
components, as well as undergo more thorough testing for heat susceptibility and
durability.
