GeForce GT 430 vs GeForce GTX 560 Ti

Intro

Compare all of that to the GeForce GTX 560 Ti, which makes use of a 40 nm design. nVidia has set the core speed at 822 MHz. The GDDR5 memory runs at a speed of 1002 MHz on this model. It features 384 SPUs as well as 64 Texture Address Units and 32 ROPs.

GeForce GTX 560 Ti		52608 Mtexels/sec
GeForce GT 430		11200 Mtexels/sec
	Difference: 41408 (370%)

Pixel Rate

The GeForce GTX 560 Ti should be much (about 839%) better at anti-aliasing than the GeForce GT 430, and also will be capable of handling higher screen resolutions more effectively. (explain)

GeForce GTX 560 Ti		26304 Mpixels/sec
GeForce GT 430		2800 Mpixels/sec
	Difference: 23504 (839%)

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 maximum amount of data (counted in MB per second) that can be transported past the external memory interface in one second. It is worked out by multiplying the card's interface width by its memory speed. In the case of DDR type RAM, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the bandwidth is, 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 processed per second. This is worked out by multiplying the total amount of texture units of the card by the core clock 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 in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly record to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
