GeForce 8800 GTX vs GeForce GTX 560 Ti

Intro

Compare all of that to the GeForce GTX 560 Ti, which features a core clock speed of 822 MHz and a GDDR5 memory frequency of 1002 MHz. It also uses a 256-bit memory bus, and makes use of a 40 nm design. It is made up of 384 SPUs, 64 TAUs, and 32 ROPs.

GeForce 8800 GTX		86400 MB/sec
	Difference: 41856 (48%)

Texel Rate

The GeForce GTX 560 Ti is much (approximately 43%) better at anisotropic filtering than the GeForce 8800 GTX. (explain)

GeForce GTX 560 Ti		52608 Mtexels/sec
GeForce 8800 GTX		36800 Mtexels/sec
	Difference: 15808 (43%)

Pixel Rate

If running with a high resolution is important to you, then the GeForce GTX 560 Ti is the winner, and very much so. (explain)

GeForce GTX 560 Ti		26304 Mpixels/sec
GeForce 8800 GTX		13800 Mpixels/sec
	Difference: 12504 (91%)

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 data (in units of MB per second) that can be transferred past the external memory interface in one second. The number is worked out by multiplying the card's interface width by its memory clock speed. If the card has DDR memory, 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 AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This number is worked out by multiplying the total amount of texture units by the core speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per 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 number is worked out by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
