GeForce 8800 GTS (G92) vs GeForce GTX 480

Intro

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

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

Memory Bandwidth

The GeForce GTX 480 should theoretically be a lot faster than the GeForce 8800 GTS (G92) in general. (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 just a bit (about 1%) more effective at texture 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

The GeForce GTX 480 should be much (more or less 223%) better at FSAA than the GeForce 8800 GTS (G92), and also will be capable of handling higher screen resolutions while still performing well. (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: Memory bandwidth is the maximum amount of information (measured in MB per second) that can be moved over the external memory interface in one second. It's calculated by multiplying the interface width by its memory speed. If the card has DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This figure is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The higher the texel rate, the better the graphics 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 most pixels the graphics card could possibly record to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also 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, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
