GeForce 8800 GT 1GB vs Geforce GTX 760

Intro

Compare those specs to the Geforce GTX 760, which has a GPU core clock speed of 980 MHz, and 2048 MB of GDDR5 RAM set to run at 1502 MHz through a 256-bit bus. It also features 1152 SPUs, 96 TAUs, and 32 Raster Operation Units.

GeForce 8800 GT 1GB		57600 MB/sec
	Difference: 134656 (234%)

Texel Rate

The Geforce GTX 760 should be a lot (approximately 180%) more effective at texture filtering than the GeForce 8800 GT 1GB. (explain)

Geforce GTX 760		94080 Mtexels/sec
GeForce 8800 GT 1GB		33600 Mtexels/sec
	Difference: 60480 (180%)

Pixel Rate

The Geforce GTX 760 should be quite a bit (approximately 227%) better at AA than the GeForce 8800 GT 1GB, and will be able to handle higher screen resolutions more effectively. (explain)

Geforce GTX 760		31360 Mpixels/sec
GeForce 8800 GT 1GB		9600 Mpixels/sec
	Difference: 21760 (227%)

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 (in units of MB per second) that can be transported across the external memory interface in one second. It is worked out by multiplying the card's interface width by its memory clock speed. If the card has DDR type memory, it should 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, 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 better 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 the graphics card could possibly record to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
