GeForce 8800 GTS (G80) 320MB vs Geforce GTX 760

Intro

Compare all of that to the Geforce GTX 760, which comes with a GPU core clock speed of 980 MHz, and 2048 MB of GDDR5 memory running at 1502 MHz through a 256-bit bus. It also features 1152 Stream Processors, 96 Texture Address Units, and 32 Raster Operation Units.

Geforce GTX 760		94080 Mtexels/sec
GeForce 8800 GTS (G80) 320MB		24624 Mtexels/sec
	Difference: 69456 (282%)

Pixel Rate

The Geforce GTX 760 should be quite a bit (approximately 206%) more effective at full screen anti-aliasing than the GeForce 8800 GTS (G80) 320MB, and also capable of handling higher screen resolutions without slowing down too much. (explain)

Geforce GTX 760		31360 Mpixels/sec
GeForce 8800 GTS (G80) 320MB		10260 Mpixels/sec
	Difference: 21100 (206%)

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 largest amount of information (counted in MB per second) that can be transported across the external memory interface in one second. The number is calculated by multiplying the interface width by its memory speed. If it uses DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per second. This figure is worked out by multiplying the total number of texture units by the core clock speed of the chip. The better this number, the better the video 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 maximum number of pixels the graphics card can 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 colour ROPs by the clock speed of the card. 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 lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
