GeForce 8800 GT 1GB vs GeForce GTX 570

Intro

Compare that to the GeForce GTX 570, which has GPU clock speed of 732 MHz, and 1280 MB of GDDR5 RAM running at 950 MHz through a 320-bit bus. It also features 480 Stream Processors, 60 TAUs, and 40 Raster Operation 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

In theory, the GeForce GTX 570 will be 164% quicker than the GeForce 8800 GT 1GB in general, because of its higher data rate. (explain)

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

Texel Rate

The GeForce GTX 570 will 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

The GeForce GTX 570 will be quite a bit (more or less 205%) more effective at FSAA than the GeForce 8800 GT 1GB, and should be capable of handling higher resolutions while still performing well. (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: Memory bandwidth is the max amount of data (in units of MB per second) that can be transported over the external memory interface in a second. It's worked out by multiplying the card's interface width by the speed of its memory. If it uses DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. 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 amount of texture map elements (texels) that can be applied per second. This number is worked out by multiplying the total number of texture units by the core clock speed of the chip. The better this number, the better the video 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 the graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
