GeForce 9800 GTX+ vs GeForce GT 430

Intro

Compare all of that to the GeForce GT 430, which has core clock speeds of 700 MHz on the GPU, and 900 MHz on the 512 MB of GDDR3 RAM. It features 96 SPUs along with 16 TAUs and 4 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 430		60 Watts
GeForce 9800 GTX+		145 Watts
	Difference: 85 Watts (142%)

Memory Bandwidth

In theory, the GeForce 9800 GTX+ is 144% faster than the GeForce GT 430 in general, because of its greater bandwidth. (explain)

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

Texel Rate

The GeForce 9800 GTX+ will be a lot (about 322%) more effective at anisotropic filtering than the GeForce GT 430. (explain)

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

Pixel Rate

The GeForce 9800 GTX+ will be quite a bit (about 322%) faster with regards to FSAA than the GeForce GT 430, and also should be able to handle higher screen resolutions without slowing down too much. (explain)

GeForce 9800 GTX+		11808 Mpixels/sec
GeForce GT 430		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 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. In the case of DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, 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 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 this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Raster Operations Pipelines by the clock 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 output rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
