GeForce GT 320 vs GeForce GT 430 1GB

Intro

Compare all of that to the GeForce GT 430 1GB, which features core speeds of 700 MHz on the GPU, and 900 MHz on the 1024 MB of GDDR3 memory. It features 96 SPUs along with 16 Texture Address Units and 4 Rasterization Operator Units.

GeForce GT 320		25280 MB/sec
	Difference: 3520 (14%)

Texel Rate

The GeForce GT 320 is just a bit (more or less 16%) better at AF than the GeForce GT 430 1GB. (explain)

GeForce GT 320		12960 Mtexels/sec
GeForce GT 430 1GB		11200 Mtexels/sec
	Difference: 1760 (16%)

Pixel Rate

If using a high screen resolution is important to you, then the GeForce GT 320 is superior to the GeForce GT 430 1GB, by a large margin. (explain)

GeForce GT 320		4320 Mpixels/sec
GeForce GT 430 1GB		2800 Mpixels/sec
	Difference: 1520 (54%)

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 information (measured in MB per second) that can be transferred past the external memory interface in one second. The number is calculated by multiplying the card's bus width by the speed of its memory. If it uses DDR type memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, 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 texture map elements (texels) that are processed per second. This figure is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The higher the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the most pixels the video card could possibly record to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
