GeForce 9800 GTX vs GeForce GT 430 (OEM)

Intro

Compare all of that to the GeForce GT 430 (OEM), which features GPU clock speed of 700 MHz, and 2048 MB of GDDR3 memory running at 900 MHz through a 128-bit bus. It also is made up of 96 SPUs, 16 Texture Address Units, and 4 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 430 (OEM)		60 Watts
GeForce 9800 GTX		140 Watts
	Difference: 80 Watts (133%)

Memory Bandwidth

Theoretically speaking, the GeForce 9800 GTX will be 144% faster than the GeForce GT 430 (OEM) overall, due to its higher bandwidth. (explain)

GeForce 9800 GTX		70400 MB/sec
GeForce GT 430 (OEM)		28800 MB/sec
	Difference: 41600 (144%)

Texel Rate

The GeForce 9800 GTX should be quite a bit (more or less 286%) faster with regards to 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

If using a high screen resolution is important to you, then the GeForce 9800 GTX is a better choice, by far. (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 max amount of data (in units of MB per second) that can be transported across the external memory interface within a second. The number is calculated by multiplying the card's interface width by its memory clock speed. If it uses DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, 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 texture map elements (texels) that can be applied per second. This number is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The higher this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the most pixels the video card can possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
