GeForce 9800 GTX+ vs GeForce GT 430 1GB

Intro

Compare that to the GeForce GT 430 1GB, which uses a 40 nm design. nVidia has clocked the core speed at 700 MHz. The GDDR3 memory is set to run at a speed of 900 MHz on this specific model. It features 96 SPUs as well as 16 Texture Address Units and 4 Rasterization Operator Units.

	Difference: 41600 (144%)

Texel Rate

The GeForce 9800 GTX+ will be a lot (about 322%) better at texture filtering than the GeForce GT 430 1GB. (explain)

GeForce 9800 GTX+		47232 Mtexels/sec
GeForce GT 430 1GB		11200 Mtexels/sec
	Difference: 36032 (322%)

Pixel Rate

The GeForce 9800 GTX+ will be quite a bit (more or less 322%) better at AA than the GeForce GT 430 1GB, and also able to handle higher screen resolutions without slowing down too much. (explain)

GeForce 9800 GTX+		11808 Mpixels/sec
GeForce GT 430 1GB		2800 Mpixels/sec
	Difference: 9008 (322%)

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 maximum amount of data (counted in megabytes per second) that can be transferred past the external memory interface in one second. It's calculated by multiplying the interface width by its memory clock speed. If it uses DDR type RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the better 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 amount of texture map elements (texels) that are processed in one second. This figure is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The higher the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount 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 fill rate also depends on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
