GeForce 8800 GTS (G92) vs GeForce GTX 560

Intro

Compare that to the GeForce GTX 560, which features a core clock frequency of 810 MHz and a GDDR5 memory frequency of 1001 MHz. It also uses a 256-bit memory bus, and makes use of a 40 nm design. It is made up of 336 SPUs, 56 Texture Address Units, and 32 Raster Operation Units.

Texel Rate

The GeForce GTX 560 will be a small bit (more or less 9%) better at anisotropic filtering than the GeForce 8800 GTS (G92). (explain)

GeForce GTX 560		45360 Mtexels/sec
GeForce 8800 GTS (G92)		41600 Mtexels/sec
	Difference: 3760 (9%)

Pixel Rate

If using a high resolution is important to you, then the GeForce GTX 560 is the winner, by a large margin. (explain)

GeForce GTX 560		25920 Mpixels/sec
GeForce 8800 GTS (G92)		10400 Mpixels/sec
	Difference: 15520 (149%)

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: Memory bandwidth is the largest amount of information (counted in megabytes per second) that can be moved past the external memory interface within a second. It is calculated by multiplying the interface width by its memory clock speed. If it uses DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher 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 number of texture map elements (texels) that can be processed in one second. This number is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The better the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
