SiS Boosts The Xabre Speed
Comdex is a time for new product announcements and SiS managed to bring an exciting product in time to be launched during the Comdex show in Las Vegas. One of them was the SiS 655 chipset and the other is the Xabre GPU.
The Xabre has always been a pretty powerful graphics processor considering that it's able to give the mainstream RADEON 7500 and GeForce4 MX a good beating. However, it is still not as popular among users and manufacturers alike. Still, SiS is determined to show the world that its technological advancements were better than popular brands like NVIDIA or ATI and it's not going to give up without a good fight.
The Xabre's attractiveness comes in its price and features. Offering the latest features that support the DirectX 8 API and the AGP 8X interface, the Xabre's specifications exceed most mainstream solutions available today. With the launch of the new Xabre 600, SiS is determined to push the Xabre further into the performance space with a more powerful GPU clock speed along with faster memory parts.
The SiS Xabre 600 GPU.
The technology behind the Xabre 600 is more or less the same as the Xabre 400. It comes with a partially software-based Vertex Shader and a hardware-accelerated Pixel Shader. Thus, you can say that it's not fully hardware T&L. SiS chose to build the Xabre this way as they believe in balancing both performance and cost. With part of the Vertex Shader executed by the CPU, SiS is able to keep the die size smaller and lower the total cost of the Xabre GPU. This has direct impact to the performance of the GPU but with faster processors, the Xabre has a better advantage since CPU acceleration could help it run faster than most mainstream graphics solutions.
