GeForce 9800 GTX vs GeForce GT 430 (OEM)

Intro

Compare all of that to the GeForce GT 430 (OEM), which has a GPU core clock speed of 700 MHz, and 2048 MB of GDDR3 memory running at 900 MHz through a 128-bit bus. It also is comprised of 96 Stream Processors, 16 TAUs, and 4 ROPs.

Texel Rate

The GeForce 9800 GTX will be a lot (about 286%) more effective at anisotropic filtering than the GeForce GT 430 (OEM). (explain)

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

Pixel Rate

The GeForce 9800 GTX should be quite a bit (more or less 286%) faster with regards to FSAA than the GeForce GT 430 (OEM), and capable of handling higher screen resolutions without losing too much performance. (explain)

GeForce 9800 GTX		10800 Mpixels/sec
GeForce GT 430 (OEM)		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 maximum amount of information (measured in MB per second) that can be transported past the external memory interface in one second. It's calculated by multiplying the card's bus width by the speed of its memory. In the case of DDR type RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly record to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
