GeForce GT 320 vs GeForce GTX 560 Ti

Intro

Compare those specs 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 RAM runs at a frequency of 1002 MHz on this card. It features 384 SPUs along with 64 TAUs and 32 Rasterization Operator Units.

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

Memory Bandwidth

The GeForce GTX 560 Ti should theoretically perform a lot faster than the GeForce GT 320 overall. (explain)

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

Texel Rate

The GeForce GTX 560 Ti is quite a bit (approximately 306%) more effective at anisotropic filtering than the GeForce GT 320. (explain)

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

Pixel Rate

If using a high screen resolution is important to you, then the GeForce GTX 560 Ti is the winner, by far. (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 maximum amount of information (measured in MB per second) that can be moved over the external memory interface in one second. The number is calculated by multiplying the bus width by its memory speed. In the case of DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed per second. This number is calculated by multiplying the total texture units by the core 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 applied in one second.

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