GeForce 8800 GTX vs GeForce GTX 560 Ti

Intro

Compare that to the GeForce GTX 560 Ti, which has a GPU core clock speed of 822 MHz, and 1024 MB of GDDR5 RAM set to run at 1002 MHz through a 256-bit bus. It also features 384 Stream Processors, 64 TAUs, and 32 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 8800 GTX		155 Watts
GeForce GTX 560 Ti		170 Watts
	Difference: 15 Watts (10%)

Memory Bandwidth

In theory, the GeForce GTX 560 Ti should be 48% quicker than the GeForce 8800 GTX overall, because of its higher bandwidth. (explain)

GeForce GTX 560 Ti		128256 MB/sec
GeForce 8800 GTX		86400 MB/sec
	Difference: 41856 (48%)

Texel Rate

The GeForce GTX 560 Ti will be quite a bit (about 43%) better at texture filtering than the GeForce 8800 GTX. (explain)

GeForce GTX 560 Ti		52608 Mtexels/sec
GeForce 8800 GTX		36800 Mtexels/sec
	Difference: 15808 (43%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GTX 560 Ti is superior to the GeForce 8800 GTX, by far. (explain)

GeForce GTX 560 Ti		26304 Mpixels/sec
GeForce 8800 GTX		13800 Mpixels/sec
	Difference: 12504 (91%)

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 (measured in megabytes per second) that can be transferred across the external memory interface in one second. It is worked out by multiplying the card's interface width by its memory speed. If it uses DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the 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 are applied per second. This number is worked out by multiplying the total amount of texture units by the core speed of the chip. The better the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
