TweakTown Rating: 8.5%Manufacturer: ECS



- AGP8X graphics card equipped with 256-bit 3D Graphics Accelerator


AGP8X supports a data rate of 2.1GB/s and runs at 533MHz, doubling the speed of the previous 266MHz AGP4X interface.


- DirectX™ 8.1


One of the big improvements of DirectX 8.1 is the Pixel Shader function, which does not exist in the DirectX 7 graphics card. With the hardware pixel shader, you can see how the light effect on the surface vividly.
