GeForce 8800 GT 1GB vs GeForce GT 430

Intro

Compare all that to the GeForce GT 430, which has a core clock frequency of 700 MHz and a GDDR3 memory frequency of 900 MHz. It also uses a 128-bit bus, and makes use of a 40 nm design. It features 96 SPUs, 16 Texture Address Units, and 4 ROPs.

GeForce 8800 GT 1GB		57600 MB/sec
GeForce GT 430		28800 MB/sec
	Difference: 28800 (100%)

Texel Rate

The GeForce 8800 GT 1GB will be a lot (about 200%) more effective at texture filtering than the GeForce GT 430. (explain)

GeForce 8800 GT 1GB		33600 Mtexels/sec
GeForce GT 430		11200 Mtexels/sec
	Difference: 22400 (200%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce 8800 GT 1GB is the winner, by a large margin. (explain)

GeForce 8800 GT 1GB		9600 Mpixels/sec
GeForce GT 430		2800 Mpixels/sec
	Difference: 6800 (243%)

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 across the external memory interface in one second. It is worked out by multiplying the card's interface width by its memory speed. If the card has DDR type RAM, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
