GeForce GT 320 vs GeForce GTX 560

Intro

Compare that to the GeForce GTX 560, which features a clock speed of 810 MHz and a GDDR5 memory frequency of 1001 MHz. It also makes use of a 256-bit memory bus, and makes use of a 40 nm design. It is made up of 336 SPUs, 56 TAUs, and 32 Raster Operation Units.

GeForce GT 320		25280 MB/sec
	Difference: 102848 (407%)

Texel Rate

The GeForce GTX 560 should be a lot (approximately 250%) better at anisotropic filtering than the GeForce GT 320. (explain)

GeForce GTX 560		45360 Mtexels/sec
GeForce GT 320		12960 Mtexels/sec
	Difference: 32400 (250%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GTX 560 is superior to the GeForce GT 320, by far. (explain)

GeForce GTX 560		25920 Mpixels/sec
GeForce GT 320		4320 Mpixels/sec
	Difference: 21600 (500%)

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 largest amount of data (measured in MB per second) that can be transported across the external memory interface within a second. The number is worked out by multiplying the card's interface width by its memory clock speed. If it uses DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the bandwidth is, 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 are processed per second. This is calculated by multiplying the total number of texture units by the core speed of the chip. The better this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

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