GeForce 8800 GTS (G92) vs GeForce GTX 480

Intro

Compare that to the GeForce GTX 480, which makes use of a 40 nm design. nVidia has set the core frequency at 700 MHz. The GDDR5 RAM runs at a speed of 924 MHz on this particular card. It features 480 SPUs as well as 60 TAUs and 48 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 8800 GTS (G92)		135 Watts
GeForce GTX 480		250 Watts
	Difference: 115 Watts (85%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 480 should be quite a bit faster than the GeForce 8800 GTS (G92) overall. (explain)

GeForce GTX 480		177408 MB/sec
GeForce 8800 GTS (G92)		62080 MB/sec
	Difference: 115328 (186%)

Texel Rate

The GeForce GTX 480 should be a small bit (about 1%) better at anisotropic filtering than the GeForce 8800 GTS (G92). (explain)

GeForce GTX 480		42000 Mtexels/sec
GeForce 8800 GTS (G92)		41600 Mtexels/sec
	Difference: 400 (1%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce GTX 480 is a better choice, and very much so. (explain)

GeForce GTX 480		33600 Mpixels/sec
GeForce 8800 GTS (G92)		10400 Mpixels/sec
	Difference: 23200 (223%)

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 largest amount of information (counted in megabytes per second) that can be transferred across the external memory interface in one second. It is calculated by multiplying the card's bus width by the speed of its memory. If the card has DDR RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied in one second. This number is calculated by multiplying the total texture units by the core clock speed of the chip. The higher this number, 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 maximum number of pixels that the graphics chip can possibly write to the local memory in one 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 - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
