GeForce 8800 GT 256MB vs GeForce GTX 560 Ti

Intro

Compare that to the GeForce GTX 560 Ti, which comes with a clock frequency of 822 MHz and a GDDR5 memory speed of 1002 MHz. It also makes use of a 256-bit bus, and makes use of a 40 nm design. It is comprised of 384 SPUs, 64 Texture Address Units, and 32 Raster Operation Units.

GeForce 8800 GT 256MB		33600 Mtexels/sec
	Difference: 19008 (57%)

Pixel Rate

The GeForce GTX 560 Ti should be much (approximately 174%) faster with regards to full screen anti-aliasing than the GeForce 8800 GT 256MB, and also should be able to handle higher resolutions without slowing down too much. (explain)

GeForce GTX 560 Ti		26304 Mpixels/sec
GeForce 8800 GT 256MB		9600 Mpixels/sec
	Difference: 16704 (174%)

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 information (in units of megabytes per second) that can be moved past the external memory interface within a second. It is calculated by multiplying the card's interface width by its memory speed. If it uses DDR RAM, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed in one second. This figure is calculated by multiplying the total amount 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 processed in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly record to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
