GeForce GT 430 1GB vs GeForce GTX 660 Ti

Intro

Compare those specifications to the GeForce GTX 660 Ti, which has core speeds of 915 MHz on the GPU, and 1500 MHz on the 2048 MB of GDDR5 memory. It features 1344 SPUs as well as 112 TAUs and 24 ROPs.

GeForce GT 430 1GB		28800 MB/sec
	Difference: 115200 (400%)

Texel Rate

The GeForce GTX 660 Ti is a lot (more or less 815%) more effective at AF than the GeForce GT 430 1GB. (explain)

GeForce GTX 660 Ti		102480 Mtexels/sec
GeForce GT 430 1GB		11200 Mtexels/sec
	Difference: 91280 (815%)

Pixel Rate

If running with a high resolution is important to you, then the GeForce GTX 660 Ti is the winner, and very much so. (explain)

GeForce GT 430 1GB		2800 Mpixels/sec
	Difference: 19160 (684%)

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 largest amount of data (measured in megabytes per second) that can be moved past the external memory interface in one second. It is calculated by multiplying the interface width by its memory clock speed. If the card has DDR type RAM, the result should be multiplied by 2 again. If 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 high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per second. This is worked out by multiplying the total number of texture units by the core clock speed of the chip. The higher the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a 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 worked out by multiplying the amount of colour ROPs by the the core 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 fill rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
