GeForce 8800 GTX vs GeForce GTX 660 Ti

Intro

Compare that to the GeForce GTX 660 Ti, which has a GPU core clock speed of 915 MHz, and 2048 MB of GDDR5 RAM running at 1500 MHz through a 192-bit bus. It also is comprised of 1344 Stream Processors, 112 Texture Address Units, and 24 Raster Operation Units.

GeForce GTX 660 Ti		150 Watts
GeForce 8800 GTX		155 Watts
	Difference: 5 Watts (3%)

Memory Bandwidth

Theoretically, the GeForce GTX 660 Ti should be quite a bit faster than the GeForce 8800 GTX in general. (explain)

GeForce GTX 660 Ti		144000 MB/sec
GeForce 8800 GTX		86400 MB/sec
	Difference: 57600 (67%)

Texel Rate

The GeForce GTX 660 Ti should be a lot (more or less 178%) faster with regards to anisotropic filtering than the GeForce 8800 GTX. (explain)

GeForce GTX 660 Ti		102480 Mtexels/sec
GeForce 8800 GTX		36800 Mtexels/sec
	Difference: 65680 (178%)

Pixel Rate

The GeForce GTX 660 Ti should be a lot (approximately 59%) more effective at anti-aliasing than the GeForce 8800 GTX, and also will be capable of handling higher screen resolutions without slowing down too much. (explain)

GeForce GTX 660 Ti		21960 Mpixels/sec
GeForce 8800 GTX		13800 Mpixels/sec
	Difference: 8160 (59%)

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 maximum amount of information (measured in MB per second) that can be moved across the external memory interface in one second. It's calculated by multiplying the card's bus width by its memory clock speed. In the case of DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, 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 number of texture map elements (texels) that are processed in one second. This is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly record to the local memory in a second - measured in millions of pixels per second. The number is calculated 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 many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
