GeForce 8800 GTX vs GeForce GT 430 1GB

Intro

Compare all of that to the GeForce GT 430 1GB, which features core clock speeds of 700 MHz on the GPU, and 900 MHz on the 1024 MB of GDDR3 memory. It features 96 SPUs as well as 16 Texture Address Units and 4 ROPs.

	Difference: 57600 (200%)

Texel Rate

The GeForce 8800 GTX will be quite a bit (about 229%) faster with regards to texture filtering than the GeForce GT 430 1GB. (explain)

GeForce 8800 GTX		36800 Mtexels/sec
GeForce GT 430 1GB		11200 Mtexels/sec
	Difference: 25600 (229%)

Pixel Rate

The GeForce 8800 GTX is a lot (more or less 393%) better at FSAA than the GeForce GT 430 1GB, and also will be capable of handling higher resolutions without slowing down too much. (explain)

GeForce 8800 GTX		13800 Mpixels/sec
GeForce GT 430 1GB		2800 Mpixels/sec
	Difference: 11000 (393%)

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 moved past the external memory interface in one second. The number is worked out by multiplying the card's interface width by the speed of its memory. If it uses DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better 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 can be processed per second. This number is calculated by multiplying the total texture units by the core clock speed of the chip. The better the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly record to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
