Notes

If you recall our original GeForce4 preview, the biggest complaint we had with the GeForce4 MX was its omission of a dedicated hardware pixel shader – this function was left to the system CPU. With Xabre, all that has changed. Unlike the GeForce4 MX or RADEON 7500, the Xabre graphics processor has a built-in pixel shader making it the first DirectX 8-compliant video card in the value segment.

Another first with Xabre is its support for AGP 8x operation. Once installed, the GPU auto-detects the proper AGP mode, ensuring optimum performance without any involvement from the end user.

Besides the integrated pixel shader, Xabre also has another advantage over GeForce4 MX in terms of fill rate. With its quad-pixel pipeline, Xabre 400 has a peak fill rate of 1.0 (4 pixels per clock x 250MHz) billion pixels/sec. In comparison, GeForce4 MX 460 only features a dual-pixel pipeline providing a fill rate of 600 Mpixels/sec (just under twice the fill rate of GeForce2 MX). In addition to its quad pixel pipeline, Xabre is able to process eight textures per pixel pipeline for eight texels per clock, equating to a fill rate of 2 billion texels/sec to GeForce4 MX’s 1.2 billion texels/sec. In terms of memory bandwidth however, the edge goes back to GeForce4 MX 460: 8.8GB/sec versus 8.0GB/sec (although Xabre can support twice as much memory as GeForce4 MX).
