VS

GeForce 8800 GS vs GeForce GT 430 (OEM)

Intro

The GeForce 8800 GS features a GPU core speed of 550 MHz, and the 384 MB of GDDR3 memory runs at 800 MHz through a 192-bit bus. It also features 96 Stream Processors, 48 Texture Address Units, and 12 ROPs.

Compare those specs to the GeForce GT 430 (OEM), which comes with GPU clock speed of 700 MHz, and 2048 MB of GDDR3 RAM set to run at 900 MHz through a 128-bit bus. It also is comprised of 96 SPUs, 16 Texture Address Units, and 4 ROPs.

The GeForce 8800 GS will be much (about 136%) more effective at texture filtering than the GeForce GT 430 (OEM). (explain)

GeForce 8800 GS 26400 Mtexels/sec
GeForce GT 430 (OEM) 11200 Mtexels/sec
Difference: 15200 (136%)

Pixel Rate

The GeForce 8800 GS is a lot (about 136%) better at full screen anti-aliasing than the GeForce GT 430 (OEM), and able to handle higher screen resolutions without slowing down too much. (explain)

GeForce 8800 GS 6600 Mpixels/sec
GeForce GT 430 (OEM) 2800 Mpixels/sec
Difference: 3800 (136%)

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.

Memory Bandwidth: Memory bandwidth is the largest amount of information (counted in megabytes per second) that can be transported past the external memory interface in one second. The number is worked out by multiplying the card's bus width by the speed of its memory. If the card has DDR type RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied per second. This figure is worked out by multiplying the total amount of texture units by the core speed of the chip. The better 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 number of pixels the graphics card could possibly write to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
