GeForce 8800 GTX vs GeForce GTX 560

Intro

Compare that to the GeForce GTX 560, which features GPU clock speed of 810 MHz, and 1024 MB of GDDR5 memory set to run at 1001 MHz through a 256-bit bus. It also features 336 Stream Processors, 56 Texture Address Units, and 32 ROPs.

GeForce GTX 560		150 Watts
GeForce 8800 GTX		155 Watts
	Difference: 5 Watts (3%)

Memory Bandwidth

Performance-wise, the GeForce GTX 560 should theoretically be quite a bit better than the GeForce 8800 GTX overall. (explain)

GeForce GTX 560		128128 MB/sec
GeForce 8800 GTX		86400 MB/sec
	Difference: 41728 (48%)

Texel Rate

The GeForce GTX 560 should be much (about 23%) more effective at AF than the GeForce 8800 GTX. (explain)

GeForce GTX 560		45360 Mtexels/sec
GeForce 8800 GTX		36800 Mtexels/sec
	Difference: 8560 (23%)

Pixel Rate

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

GeForce GTX 560		25920 Mpixels/sec
GeForce 8800 GTX		13800 Mpixels/sec
	Difference: 12120 (88%)

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: Memory bandwidth is the largest amount of information (in units of MB per second) that can be transported across 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, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher 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 number of texture map elements (texels) that are applied in one second. This is worked out 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 texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines by the the core 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 is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
