GeForce 8800 Ultra vs GeForce GTX 560 Ti

Intro

Compare those specifications to the GeForce GTX 560 Ti, which comes with core clock speeds of 822 MHz on the GPU, and 1002 MHz on the 1024 MB of GDDR5 RAM. It features 384 SPUs as well as 64 TAUs and 32 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 560 Ti		170 Watts
GeForce 8800 Ultra		171 Watts
	Difference: 1 Watts (1%)

Memory Bandwidth

The GeForce GTX 560 Ti, in theory, should perform quite a bit faster than the GeForce 8800 Ultra overall. (explain)

GeForce GTX 560 Ti		128256 MB/sec
GeForce 8800 Ultra		103680 MB/sec
	Difference: 24576 (24%)

Texel Rate

The GeForce GTX 560 Ti should be a lot (approximately 34%) faster with regards to 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

If using high levels of AA is important to you, then the GeForce GTX 560 Ti is superior to the GeForce 8800 Ultra, and very much so. (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 information (counted in MB per second) that can be transferred across the external memory interface in a second. The number is calculated by multiplying the card's interface width by the speed of its memory. If it uses DDR type RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed per second. This figure is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the video 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 the video card 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 colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
