GeForce 8800 GT 1GB vs GeForce GT 430 1GB

Intro

Compare all of that to the GeForce GT 430 1GB, which features a core clock frequency of 700 MHz and a GDDR3 memory frequency of 900 MHz. It also makes use of a 128-bit memory bus, and uses a 40 nm design. It is made up of 96 SPUs, 16 Texture Address Units, and 4 ROPs.

	Difference: 28800 (100%)

Texel Rate

The GeForce 8800 GT 1GB should be quite a bit (approximately 200%) faster with regards to anisotropic filtering than the GeForce GT 430 1GB. (explain)

GeForce 8800 GT 1GB		33600 Mtexels/sec
GeForce GT 430 1GB		11200 Mtexels/sec
	Difference: 22400 (200%)

Pixel Rate

If running with a high screen resolution is important to you, then the GeForce 8800 GT 1GB is a better choice, by a large margin. (explain)

GeForce 8800 GT 1GB		9600 Mpixels/sec
GeForce GT 430 1GB		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 (in units of megabytes per second) that can be moved across the external memory interface in a second. The number is calculated by multiplying the bus width by its memory speed. If it uses DDR type memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied in one second. This number is calculated by multiplying the total 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 applied in one second.

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly write to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
