GeForce 8800 GT 1GB vs GeForce GTX 560

Intro

Compare all of that to the GeForce GTX 560, which features a GPU core clock speed of 810 MHz, and 1024 MB of GDDR5 RAM running at 1001 MHz through a 256-bit bus. It also is comprised of 336 Stream Processors, 56 TAUs, and 32 ROPs.

GeForce 8800 GT 1GB		57600 MB/sec
	Difference: 70528 (122%)

Texel Rate

The GeForce GTX 560 is much (about 35%) better at texture filtering than the GeForce 8800 GT 1GB. (explain)

GeForce GTX 560		45360 Mtexels/sec
GeForce 8800 GT 1GB		33600 Mtexels/sec
	Difference: 11760 (35%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce GTX 560 is the winner, by far. (explain)

GeForce GTX 560		25920 Mpixels/sec
GeForce 8800 GT 1GB		9600 Mpixels/sec
	Difference: 16320 (170%)

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 data (counted in MB per second) that can be moved over the external memory interface in one second. It's calculated by multiplying the bus width by its memory clock speed. If the card has DDR RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, 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 number of texture map elements (texels) that can be applied per second. This number is calculated by multiplying the total number of texture units by the core clock speed of the chip. The higher this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the most pixels the video card could possibly record to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Raster Operations Pipelines by the the core 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 rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
