GeForce 8800 GS vs GeForce GT 430 1GB

Intro

Compare those specs to the GeForce GT 430 1GB, which comes with GPU clock speed of 700 MHz, and 1024 MB of GDDR3 RAM running at 900 MHz through a 128-bit bus. It also is made up of 96 SPUs, 16 TAUs, and 4 Raster Operation Units.

	Difference: 45 Watts (75%)

Memory Bandwidth

In theory, the GeForce 8800 GS will be 33% quicker than the GeForce GT 430 1GB overall, because of its higher data rate. (explain)

GeForce 8800 GS		38400 MB/sec
GeForce GT 430 1GB		28800 MB/sec
	Difference: 9600 (33%)

Texel Rate

The GeForce 8800 GS is quite a bit (approximately 136%) faster with regards to AF than the GeForce GT 430 1GB. (explain)

GeForce 8800 GS		26400 Mtexels/sec
GeForce GT 430 1GB		11200 Mtexels/sec
	Difference: 15200 (136%)

Pixel Rate

The GeForce 8800 GS should be quite a bit (approximately 136%) more effective at AA than the GeForce GT 430 1GB, and also will be capable of handling higher resolutions more effectively. (explain)

GeForce 8800 GS		6600 Mpixels/sec
GeForce GT 430 1GB		2800 Mpixels/sec
	Difference: 3800 (136%)

Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.

Specifications

Memory Bandwidth: Bandwidth is the largest amount of information (measured in megabytes per second) that can be transferred past the external memory interface in a second. It is worked out by multiplying the card's interface width by its memory speed. In the case of DDR type memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This number is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly record to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
