GeForce 8800 GT 1GB vs GeForce GTX 480

Intro

Compare that to the GeForce GTX 480, which comes with a core clock frequency of 700 MHz and a GDDR5 memory frequency of 924 MHz. It also features a 384-bit memory bus, and uses a 40 nm design. It is comprised of 480 SPUs, 60 Texture Address Units, and 48 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 8800 GT 1GB		105 Watts
GeForce GTX 480		250 Watts
	Difference: 145 Watts (138%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 480 should perform quite a bit faster than the GeForce 8800 GT 1GB overall. (explain)

GeForce GTX 480		177408 MB/sec
GeForce 8800 GT 1GB		57600 MB/sec
	Difference: 119808 (208%)

Texel Rate

The GeForce GTX 480 will be a lot (approximately 25%) faster with regards to anisotropic filtering than the GeForce 8800 GT 1GB. (explain)

GeForce GTX 480		42000 Mtexels/sec
GeForce 8800 GT 1GB		33600 Mtexels/sec
	Difference: 8400 (25%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce GTX 480 is superior to the GeForce 8800 GT 1GB, and very much so. (explain)

GeForce GTX 480		33600 Mpixels/sec
GeForce 8800 GT 1GB		9600 Mpixels/sec
	Difference: 24000 (250%)

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 MB per second) that can be transported over the external memory interface in a second. The number is worked out by multiplying the interface width by its memory speed. In the case of DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the 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 number of texture map elements (texels) that are processed per second. This figure is worked out by multiplying the total number of texture units by the core speed of the chip. The higher the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the most pixels the video card could possibly record to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
