GeForce 8800 GTX vs GeForce GTX 560 Ti

Intro

Compare all of that to the GeForce GTX 560 Ti, which comes with GPU clock speed of 822 MHz, and 1024 MB of GDDR5 RAM running at 1002 MHz through a 256-bit bus. It also is made up of 384 Stream Processors, 64 Texture Address Units, and 32 ROPs.

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

Memory Bandwidth

Performance-wise, the GeForce GTX 560 Ti should in theory be quite a bit superior to the GeForce 8800 GTX overall. (explain)

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

Texel Rate

The GeForce GTX 560 Ti should be quite a bit (more or less 43%) more effective at AF than the GeForce 8800 GTX. (explain)

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

Pixel Rate

The GeForce GTX 560 Ti should be much (approximately 91%) better at AA than the GeForce 8800 GTX, and also capable of handling higher screen resolutions without slowing down too much. (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 data (counted in MB per second) that can be transported over the external memory interface in one second. It's worked out by multiplying the interface width by the speed of its memory. If it uses DDR memory, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the 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 can be processed in one second. This figure is calculated by multiplying the total number of texture units by the core 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 in a second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Render Output Units 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 fill rate also depends on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
