GeForce GT 440 1.5GB vs GeForce GTX 460 SE

Intro

Compare all of that to the GeForce GTX 460 SE, which has clock speeds of 650 MHz on the GPU, and 850 MHz on the 1024 MB of GDDR5 memory. It features 288 SPUs along with 48 Texture Address Units and 32 Rasterization Operator Units.

GeForce GT 440 1.5GB		56 Watts
GeForce GTX 460 SE		150 Watts
	Difference: 94 Watts (168%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 460 SE should be 152% faster than the GeForce GT 440 1.5GB overall, because of its higher bandwidth. (explain)

GeForce GTX 460 SE		108800 MB/sec
GeForce GT 440 1.5GB		43200 MB/sec
	Difference: 65600 (152%)

Texel Rate

The GeForce GTX 460 SE will be much (about 119%) better at AF than the GeForce GT 440 1.5GB. (explain)

GeForce GTX 460 SE		31200 Mtexels/sec
GeForce GT 440 1.5GB		14256 Mtexels/sec
	Difference: 16944 (119%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GTX 460 SE is a better choice, by a large margin. (explain)

GeForce GTX 460 SE		20800 Mpixels/sec
GeForce GT 440 1.5GB		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: Memory bandwidth is the max amount of information (in units of megabytes per second) that can be transferred past the external memory interface within a second. It's calculated by multiplying the interface width by its memory speed. If the card has DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, 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 in one second. This figure is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The higher the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
