GeForce 9800 GTX vs GeForce GT 430 1GB

Intro

Compare those specifications to the GeForce GT 430 1GB, which has a clock frequency of 700 MHz and a GDDR3 memory frequency of 900 MHz. It also makes use of a 128-bit bus, and uses a 40 nm design. It is made up of 96 SPUs, 16 TAUs, and 4 Raster Operation Units.

GeForce GT 430 1GB		28800 MB/sec
	Difference: 41600 (144%)

Texel Rate

The GeForce 9800 GTX should be quite a bit (about 286%) better at texture filtering than the GeForce GT 430 1GB. (explain)

GeForce 9800 GTX		43200 Mtexels/sec
GeForce GT 430 1GB		11200 Mtexels/sec
	Difference: 32000 (286%)

Pixel Rate

If running with a high screen resolution is important to you, then the GeForce 9800 GTX is a better choice, and very much so. (explain)

GeForce 9800 GTX		10800 Mpixels/sec
GeForce GT 430 1GB		2800 Mpixels/sec
	Difference: 8000 (286%)

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 across the external memory interface in a second. It is calculated by multiplying the interface width by its memory speed. In the case of DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels the video card could possibly write to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of ROPs 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 fill 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 get to the max fill rate.
