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 clocked the core speed at 700 MHz. The GDDR3 RAM runs at a speed of 900 MHz on this specific card. It features 96 SPUs along with 16 Texture Address Units and 4 Rasterization Operator Units.

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

Texel Rate

The GeForce 9800 GTX will be a lot (approximately 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

If using lots of anti-aliasing is important to you, then the GeForce 9800 GTX is superior to the GeForce GT 430, by far. (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: Memory bandwidth is the largest amount of information (counted in megabytes per second) that can be moved over the external memory interface in a second. It's worked out by multiplying the bus width by its memory speed. If the card has DDR memory, the result should be multiplied by 2 again. If it uses 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 high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly write to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
