GeForce 8800 GT 512MB vs GeForce GT 430 (OEM)

Intro

Compare those specs to the GeForce GT 430 (OEM), which makes use of a 40 nm design. nVidia has set the core speed at 700 MHz. The GDDR3 RAM runs at a speed of 900 MHz on this specific model. It features 96 SPUs along with 16 TAUs and 4 ROPs.

	Difference: 28800 (100%)

Texel Rate

The GeForce 8800 GT 512MB will be a lot (more or less 200%) more effective at AF than the GeForce GT 430 (OEM). (explain)

GeForce 8800 GT 512MB		33600 Mtexels/sec
GeForce GT 430 (OEM)		11200 Mtexels/sec
	Difference: 22400 (200%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce 8800 GT 512MB is superior to the GeForce GT 430 (OEM), and very much so. (explain)

GeForce 8800 GT 512MB		9600 Mpixels/sec
GeForce GT 430 (OEM)		2800 Mpixels/sec
	Difference: 6800 (243%)

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 largest amount of data (measured in megabytes per second) that can be transferred past the external memory interface in a second. It is worked out by multiplying the card's bus width by its memory clock speed. If it uses DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed per second. This figure is worked out by multiplying the total number 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 applied per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly record to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of Raster Operations Pipelines by the clock 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 fill rate is also dependant on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
