GeForce 8800 GTS (G92) vs GeForce GTX 570

Intro

Compare those specifications to the GeForce GTX 570, which has GPU clock speed of 732 MHz, and 1280 MB of GDDR5 RAM set to run at 950 MHz through a 320-bit bus. It also is made up of 480 SPUs, 60 Texture Address Units, and 40 Raster Operation Units.

Memory Bandwidth

As far as performance goes, the GeForce GTX 570 should theoretically be quite a bit superior to the GeForce 8800 GTS (G92) in general. (explain)

GeForce GTX 570		152000 MB/sec
GeForce 8800 GTS (G92)		62080 MB/sec
	Difference: 89920 (145%)

Texel Rate

The GeForce GTX 570 is a bit (more or less 6%) better at anisotropic filtering than the GeForce 8800 GTS (G92). (explain)

GeForce GTX 570		43920 Mtexels/sec
GeForce 8800 GTS (G92)		41600 Mtexels/sec
	Difference: 2320 (6%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GTX 570 is a better choice, by a large margin. (explain)

GeForce GTX 570		29280 Mpixels/sec
GeForce 8800 GTS (G92)		10400 Mpixels/sec
	Difference: 18880 (182%)

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 maximum amount of data (in units of MB per second) that can be transferred over the external memory interface in a second. The number is worked out by multiplying the card's bus width by the speed of its memory. In the case of DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster 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 are applied in one second. This number is worked out by multiplying the total number of texture units by the core clock speed of the chip. The higher the texel rate, 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 can possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
