Amd has used the 80nm technology, succeeding to implement 700 millions of transistors. The memory controller GDDR3 (on HD 2900 XTX are previewed GGDR4 memories) has a bandwidth of 512 bit.
The first notable thing is the high frequency of the gpu, 740 MHz against the 500 of the 8800 GTS 640MB. The quantity of ram (512 MB GDDR3 working at a frequency of 825 MHz), is inferior of the one used on the Nvidia card. In the other hand, the difference of bandwidth is considerable: 106 GB/sec for AMD/ATI against 64 GB/sec for Nvidia 8800 GTS 640 MB).
The pci-e interface is compatible with the 16x channel. The master/slave solution for the CrossFire configuration has been abandoned, substituted by the multi gpu solution. This video card is fully compatible with the last DirectX 10, released by Microsoft at the same time of his new operative system, Windows Vista.
As ever for Ati, there are a lot of features to guarantee the maximum video quality, the engineers has implemented innovative solutions to take massive vantage of new multimedia supports like DVD, HD DVD and Blue-ray. These functionalities take the name of ATI Avivo HD and include:
- UVD (Unified Video Decoder): it's a new HD video processor that decodes in hardware the signal from HD DVD and Blue-Ray. Special cure has been used for energy saving.
- Full support the multichannel audio 5.1 on HDMI cable.
Other important multimedia features are:
- Support to all VGA monitor until the resolution of 2048x1536
- HDMI support until the resolution of 1920x1080 and 1080p format.
- Integrated HD audio controller multi-channel (5.1) AC3 support
- Integrated Xilleon™ HDTV encoder , support analogical out for high quality TV (component/Svideo/composite), support SDTV ecHDTV resolutions
Especially cured (like ATI tradition) the user interface of the new specific Catalyst drivers for HD 2900 XT, periodically released and DirectX 10 certified, like said before
