GeForce GT 440 3GB vs GeForce GTX 460 SE

Intro

Compare all that to the GeForce GTX 460 SE, which has a GPU core clock speed of 650 MHz, and 1024 MB of GDDR5 memory running at 850 MHz through a 256-bit bus. It also is comprised of 288 SPUs, 48 TAUs, and 32 Raster Operation Units.

GeForce GT 440 3GB		43200 MB/sec
	Difference: 65600 (152%)

Texel Rate

The GeForce GTX 460 SE should be quite a bit (more or less 119%) better at texture filtering than the GeForce GT 440 3GB. (explain)

GeForce GTX 460 SE		31200 Mtexels/sec
GeForce GT 440 3GB		14256 Mtexels/sec
	Difference: 16944 (119%)

Pixel Rate

If running with a high resolution is important to you, then the GeForce GTX 460 SE is a better choice, and very much so. (explain)

GeForce GTX 460 SE		20800 Mpixels/sec
GeForce GT 440 3GB		14256 Mpixels/sec
	Difference: 6544 (46%)

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 information (measured in MB per second) that can be moved over the external memory interface in a second. The number is worked out by multiplying the bus width by its memory speed. In the case of DDR memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied per second. This figure is calculated by multiplying the total texture units by the core clock speed of the chip. The better the texel rate, the better the card will be at 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 card can possibly record to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
