GeForce 8800 GT 1GB vs GeForce GTX 570

Intro

Compare that to the GeForce GTX 570, which comes with clock 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 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 8800 GT 1GB		105 Watts
GeForce GTX 570		219 Watts
	Difference: 114 Watts (109%)

Memory Bandwidth

As far as performance goes, the GeForce GTX 570 should in theory be a lot better than the GeForce 8800 GT 1GB in general. (explain)

GeForce GTX 570		152000 MB/sec
GeForce 8800 GT 1GB		57600 MB/sec
	Difference: 94400 (164%)

Texel Rate

The GeForce GTX 570 should be quite a bit (more or less 31%) more effective at anisotropic filtering than the GeForce 8800 GT 1GB. (explain)

GeForce GTX 570		43920 Mtexels/sec
GeForce 8800 GT 1GB		33600 Mtexels/sec
	Difference: 10320 (31%)

Pixel Rate

If using a high resolution is important to you, then the GeForce GTX 570 is the winner, and very much so. (explain)

GeForce GTX 570		29280 Mpixels/sec
GeForce 8800 GT 1GB		9600 Mpixels/sec
	Difference: 19680 (205%)

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 (measured in megabytes per second) that can be moved over the external memory interface within a second. The number is worked out by multiplying the card's bus width by its memory speed. If the card has DDR memory, it must 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 high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed in one second. This figure is calculated 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 processed in one second.

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on lots of 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.
