GeForce 8800 GTX vs GeForce GT 430

Intro

Compare those specifications to the GeForce GT 430, which comes with 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 8800 GTX		155 Watts
	Difference: 95 Watts (158%)

Memory Bandwidth

The GeForce 8800 GTX should theoretically perform much faster than the GeForce GT 430 in general. (explain)

GeForce 8800 GTX		86400 MB/sec
GeForce GT 430		28800 MB/sec
	Difference: 57600 (200%)

Texel Rate

The GeForce 8800 GTX should be quite a bit (about 229%) more effective at anisotropic filtering than the GeForce GT 430. (explain)

GeForce 8800 GTX		36800 Mtexels/sec
GeForce GT 430		11200 Mtexels/sec
	Difference: 25600 (229%)

Pixel Rate

If using a high resolution is important to you, then the GeForce 8800 GTX is superior to the GeForce GT 430, and very much so. (explain)

GeForce 8800 GTX		13800 Mpixels/sec
GeForce GT 430		2800 Mpixels/sec
	Difference: 11000 (393%)

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 maximum amount of data (in units of MB per second) that can be transported over the external memory interface in a second. It is worked out by multiplying the bus width by its memory clock speed. If it uses DDR type 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 anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate 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 outputting the pixels (image) to the screen. The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
