The 6600 XXX Edition is based upon NVIDIA's NV43 chip. NVIDIA introduced the NV4x architecture in April of 2004 with the release of the 6800 Ultra, the 6800GT and the 6800. NVIDIA released the 6600GT a little later in 2004 for a MSRP of $199. Late last year NVIDIA released the 6600 256MB card. The key features of the 6600 include Pixel Shader 3.0 and Vertex Shader 3.0 support. I've covered both in previous reviews on the 6xxx series from NVIDIA so if you want more information you can visit my previous reviews on the 6800GT via this link to my 6800GT review.

The XFX XXX Edition differentiates itself from their standard card in two different ways. First, the core clock speed is 450MHz, a 75MHz clock increase over the standard 6600 256MB card based upon NVIDIA's reference design. This gives a maximum theoretical fillrate of 3.6 Gigapixels a second. The memory bandwidth on this card is 12.8GB a second, due to the 800MHz memory clock and a 128-bit memory bus (800x2/8x128=12800 megabytes memory bandwith). I was able to overclock the card to 482MHz/867MHz for the core/memory a decent overclock.
