GeForce 8800 Ultra vs GeForce GTX 560 Ti

Intro

Compare all of that to the GeForce GTX 560 Ti, which makes use of a 40 nm design. nVidia has clocked the core speed at 822 MHz. The GDDR5 memory works at a speed of 1002 MHz on this particular model. It features 384 SPUs along with 64 Texture Address Units and 32 Rasterization Operator Units.

GeForce 8800 Ultra		103680 MB/sec
	Difference: 24576 (24%)

Texel Rate

The GeForce GTX 560 Ti is a lot (more or less 34%) more effective at texture filtering than the GeForce 8800 Ultra. (explain)

GeForce GTX 560 Ti		52608 Mtexels/sec
GeForce 8800 Ultra		39168 Mtexels/sec
	Difference: 13440 (34%)

Pixel Rate

The GeForce GTX 560 Ti should be much (about 79%) better at anti-aliasing than the GeForce 8800 Ultra, and also will be able to handle higher screen resolutions without slowing down too much. (explain)

GeForce GTX 560 Ti		26304 Mpixels/sec
GeForce 8800 Ultra		14688 Mpixels/sec
	Difference: 11616 (79%)

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 within a second. It is calculated by multiplying the interface width by its memory speed. If it uses DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are 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 this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly write to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
