GeForce GT 320 vs GeForce GTX 560 Ti

Intro

Compare all that to the GeForce GTX 560 Ti, which features clock speeds of 822 MHz on the GPU, and 1002 MHz on the 1024 MB of GDDR5 RAM. It features 384 SPUs as well as 64 TAUs and 32 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 320		43 Watts
GeForce GTX 560 Ti		170 Watts
	Difference: 127 Watts (295%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 560 Ti will be 407% faster than the GeForce GT 320 in general, because of its higher data rate. (explain)

GeForce GTX 560 Ti		128256 MB/sec
GeForce GT 320		25280 MB/sec
	Difference: 102976 (407%)

Texel Rate

The GeForce GTX 560 Ti should be quite a bit (more or less 306%) better at AF than the GeForce GT 320. (explain)

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

Pixel Rate

The GeForce GTX 560 Ti will be quite a bit (more or less 509%) faster with regards to FSAA than the GeForce GT 320, and capable of handling higher 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: Bandwidth is the max amount of data (in units of MB per second) that can be transferred over the external memory interface in one second. The number is worked out by multiplying the card's interface width by the speed of its memory. In the case of DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, 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 in one second. This figure is worked out by multiplying the total amount of texture units by the core speed of the chip. The higher this number, the better the 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 can possibly write to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
