ECS Xabre 400 AG400T8-D64 Review (0)
Overclocker 21 June 2002

The long awaited 8X AGP card based on the SiS Xabre 400 chipset is finally here. Being one of the first players to launch an 8x AGP product, it definitely a challenge to make it a real competitive product to the current available 4x AGP cards on the market. Revamped in a beautiful Japanese looking package, ECS has evolved from a low cost OEM manufacturer to a company that not only does the value segment but also the mid -range segment. 

AG400T8-64 is a 64MB DirectX8.1 AGP 8x card. It uses 3.3ns 64MB DDR SDRAM and supports tv-out and 3D glasses. It has a Memory Clk : DDR 500Mhz, Engine Clk : 250 Mhz. It uses the SiS301 chip for NTSC and PAL encoding for TV-OUT and it could be used for dual display or mirror display.

Below are the detail specifications and on the next few pages are the gallery and benchmarks.
