Leadtek WinFast PX6600GT TDH - PAGE 1Terren Tong - Wednesday, January 26th, 2005
Introduction
Although Leadtek manufactures a lot of other products including TV Tuners and GPS units, most hardware enthusiasts know the Leadtek name from their long involvement in the video card industry. I believe that they are currently the oldest NVIDIA board partner as I seem to remember that they had products stretching back into the RIVA128 days alongside my old Diamond Viper card. While the likes of Diamond, Creative, Elsa and other once prominent names in the industry have bowed out over the years, Leadtek has kept up in the very competitive video card segment.
The first time we took a look at a 6600GT SLI combo, it was not a very typical configuration - it was a single card, dual core approach from Gigabyte's 3D1. Today we'll be taking a look at a pair of Leadtek 6600GT's. On the benchmark front, the Leadtek pair will be featured in both a single card and dual card configuration up against a single 6800GT as well as Gigabyte's 3D1.

The 6600GT is the slowest card in the GeForce 6 family that supports SLI but slow is relative - it is easily the fastest card currently available in the 200$ price range (though there will be a good amount of pressure that will be put on it should ATI get the X800 to the market in volume). The 6600GT compares favorably to the 6800 - the only thing that holds it back somewhat is the memory interface which has been sliced to 128-bit compared to the 6800 series.
