GeForce 8800 Ultra vs GeForce GTX 560

Intro

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

GeForce GTX 560		150 Watts
GeForce 8800 Ultra		171 Watts
	Difference: 21 Watts (14%)

Memory Bandwidth

In theory, the GeForce GTX 560 should be 24% faster than the GeForce 8800 Ultra overall, due to its higher data rate. (explain)

GeForce GTX 560		128128 MB/sec
GeForce 8800 Ultra		103680 MB/sec
	Difference: 24448 (24%)

Texel Rate

The GeForce GTX 560 should be a small bit (about 16%) better at AF than the GeForce 8800 Ultra. (explain)

GeForce GTX 560		45360 Mtexels/sec
GeForce 8800 Ultra		39168 Mtexels/sec
	Difference: 6192 (16%)

Pixel Rate

The GeForce GTX 560 should be much (about 76%) faster with regards to FSAA than the GeForce 8800 Ultra, and also able to handle higher resolutions without slowing down too much. (explain)

GeForce GTX 560		25920 Mpixels/sec
GeForce 8800 Ultra		14688 Mpixels/sec
	Difference: 11232 (76%)

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 data (in units of MB per second) that can be transported past the external memory interface in a second. It is calculated by multiplying the bus width by its memory clock speed. If the card has DDR type memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's 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 amount of texture map elements (texels) that are processed in one second. This number is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The higher the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum amount 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 number of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
