GeForce 8800 GTX vs GeForce GTX 570

Intro

Compare all of that to the GeForce GTX 570, which features core speeds of 732 MHz on the GPU, and 950 MHz on the 1280 MB of GDDR5 RAM. It features 480 SPUs along with 60 TAUs and 40 ROPs.

GeForce 8800 GTX		86400 MB/sec
	Difference: 65600 (76%)

Texel Rate

The GeForce GTX 570 should be a bit (about 19%) more effective at AF than the GeForce 8800 GTX. (explain)

GeForce GTX 570		43920 Mtexels/sec
GeForce 8800 GTX		36800 Mtexels/sec
	Difference: 7120 (19%)

Pixel Rate

The GeForce GTX 570 should be a lot (more or less 112%) more effective at full screen anti-aliasing than the GeForce 8800 GTX, and also should be able to handle higher screen resolutions better. (explain)

GeForce GTX 570		29280 Mpixels/sec
GeForce 8800 GTX		13800 Mpixels/sec
	Difference: 15480 (112%)

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 information (in units of MB per second) that can be moved past the external memory interface within a second. The number is calculated by multiplying the card's interface width by the speed of its memory. If the card has DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, 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 worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of ROPs by the clock 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 output rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
