GeForce 8800 Ultra vs GeForce GTX 460 1GB

Intro

Compare those specifications to the GeForce GTX 460 1GB, which has core speeds of 675 MHz on the GPU, and 900 MHz on the 1024 MB of GDDR5 memory. It features 336 SPUs as well as 56 Texture Address Units and 32 ROPs.

GeForce 8800 Ultra		103680 MB/sec
	Difference: 11520 (11%)

Texel Rate

The GeForce 8800 Ultra is just a bit (more or less 4%) more effective at anisotropic filtering than the GeForce GTX 460 1GB. (explain)

GeForce 8800 Ultra		39168 Mtexels/sec
GeForce GTX 460 1GB		37800 Mtexels/sec
	Difference: 1368 (4%)

Pixel Rate

The GeForce GTX 460 1GB will be quite a bit (approximately 47%) more effective at FSAA than the GeForce 8800 Ultra, and should be able to handle higher screen resolutions without slowing down too much. (explain)

GeForce GTX 460 1GB		21600 Mpixels/sec
GeForce 8800 Ultra		14688 Mpixels/sec
	Difference: 6912 (47%)

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 maximum amount of data (in units of MB per second) that can be transported past the external memory interface in one second. The number is worked out by multiplying the card's bus width by its memory speed. In the case of DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied per second. This number is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on 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 get to the max fill rate.
