GeForce GT 320 vs GeForce GTX 560 Ti

Intro

Compare that to the GeForce GTX 560 Ti, which has GPU core speed of 822 MHz, and 1024 MB of GDDR5 RAM set to run at 1002 MHz through a 256-bit bus. It also is comprised of 384 Stream Processors, 64 TAUs, and 32 Raster Operation Units.

GeForce GTX 560 Ti		52608 Mtexels/sec
GeForce GT 320		12960 Mtexels/sec
	Difference: 39648 (306%)

Pixel Rate

The GeForce GTX 560 Ti should be quite a bit (approximately 509%) better at anti-aliasing than the GeForce GT 320, and also able to handle higher screen resolutions more effectively. (explain)

GeForce GTX 560 Ti		26304 Mpixels/sec
GeForce GT 320		4320 Mpixels/sec
	Difference: 21984 (509%)

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 (in units of megabytes per second) that can be transported across the external memory interface in a second. The number is calculated by multiplying the interface width by its memory clock speed. In the case of DDR type memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The better the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate 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 also depends on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
