GeForce 9800 GTX vs GeForce GT 430

Intro

Compare all of that to the GeForce GT 430, which makes use of a 40 nm design. nVidia has set the core speed at 700 MHz. The GDDR3 memory is set to run at a speed of 900 MHz on this card. It features 96 SPUs as well as 16 TAUs and 4 ROPs.

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

Texel Rate

The GeForce 9800 GTX should be much (more or less 286%) more effective at AF than the GeForce GT 430. (explain)

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

Pixel Rate

The GeForce 9800 GTX should be much (about 286%) more effective at FSAA than the GeForce GT 430, and capable of handling higher resolutions more effectively. (explain)

GeForce 9800 GTX		10800 Mpixels/sec
GeForce GT 430		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 data (measured in MB per second) that can be transferred over the external memory interface in a second. It is calculated by multiplying the bus width by its memory speed. If the card has DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher 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 per second. This figure is calculated by multiplying the total amount of 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 processed in a second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number 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 also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
