GeForce 8800 GS vs GeForce GT 430 1GB

Intro

Compare those specifications to the GeForce GT 430 1GB, which comes with GPU core speed of 700 MHz, and 1024 MB of GDDR3 RAM running at 900 MHz through a 128-bit bus. It also is comprised of 96 Stream Processors, 16 Texture Address Units, and 4 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 430 1GB		60 Watts
GeForce 8800 GS		105 Watts
	Difference: 45 Watts (75%)

Memory Bandwidth

Theoretically speaking, the GeForce 8800 GS will be 33% faster than the GeForce GT 430 1GB in general, due to 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 will be a lot (about 136%) more effective at anisotropic filtering 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

If running with lots of anti-aliasing is important to you, then the GeForce 8800 GS is the winner, and very much so. (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 max amount of information (measured in MB per second) that can be transferred over the external memory interface in one second. It's worked out by multiplying the card's bus width by its memory clock speed. In the case of DDR type RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of 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 number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
