GeForce 8800 GS vs GeForce GT 440 1.5GB

Intro

Compare all that to the GeForce GT 440 1.5GB, which uses a 40 nm design. nVidia has clocked the core frequency at 594 MHz. The GDDR3 memory is set to run at a speed of 900 MHz on this card. It features 144 SPUs as well as 24 TAUs and 24 Rasterization Operator Units.

Texel Rate

The GeForce 8800 GS should be a lot (more or less 85%) more effective at texture filtering than the GeForce GT 440 1.5GB. (explain)

GeForce 8800 GS		26400 Mtexels/sec
GeForce GT 440 1.5GB		14256 Mtexels/sec
	Difference: 12144 (85%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce GT 440 1.5GB is superior to the GeForce 8800 GS, by far. (explain)

GeForce GT 440 1.5GB		14256 Mpixels/sec
GeForce 8800 GS		6600 Mpixels/sec
	Difference: 7656 (116%)

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 (measured in megabytes per second) that can be transferred across the external memory interface in a second. The number is calculated by multiplying the interface width by the speed of its memory. If it uses DDR type RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Raster Operations Pipelines by the the core 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 lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
