Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 8800 GTX		155 Watts
Geforce GTX 760		170 Watts
	Difference: 15 Watts (10%)

Memory Bandwidth

Theoretically speaking, the Geforce GTX 760 should be 123% faster than the GeForce 8800 GTX overall, due to its higher data rate. (explain)

Geforce GTX 760		192256 MB/sec
GeForce 8800 GTX		86400 MB/sec
	Difference: 105856 (123%)

Texel Rate

The Geforce GTX 760 should be quite a bit (more or less 156%) faster with regards to AF than the GeForce 8800 GTX. (explain)

Geforce GTX 760		94080 Mtexels/sec
GeForce 8800 GTX		36800 Mtexels/sec
	Difference: 57280 (156%)

Pixel Rate

The Geforce GTX 760 is quite a bit (about 127%) faster with regards to AA than the GeForce 8800 GTX, and will be capable of handling higher resolutions without slowing down too much. (explain)

Geforce GTX 760		31360 Mpixels/sec
GeForce 8800 GTX		13800 Mpixels/sec
	Difference: 17560 (127%)

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 past the external memory interface in a second. It is calculated by multiplying the bus width by the speed of its memory. If the card has DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed per second. This is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The better this number, the better the 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 maximum number of pixels the video card could possibly record to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Raster Operations Pipelines 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 output rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
