GeForce GT 440 3GB vs GeForce GTX 560 Ti

Intro

Compare those specifications to the GeForce GTX 560 Ti, which uses a 40 nm design. nVidia has set the core speed at 822 MHz. The GDDR5 memory works at a speed of 1002 MHz on this particular model. It features 384 SPUs as well as 64 Texture Address Units and 32 Rasterization Operator Units.

GeForce GT 440 3GB		43200 MB/sec
	Difference: 85056 (197%)

Texel Rate

The GeForce GTX 560 Ti will be quite a bit (approximately 269%) better at texture filtering than the GeForce GT 440 3GB. (explain)

GeForce GTX 560 Ti		52608 Mtexels/sec
GeForce GT 440 3GB		14256 Mtexels/sec
	Difference: 38352 (269%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GTX 560 Ti is a better choice, and very much so. (explain)

GeForce GTX 560 Ti		26304 Mpixels/sec
GeForce GT 440 3GB		14256 Mpixels/sec
	Difference: 12048 (85%)

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 transferred over the external memory interface in a second. It's calculated by multiplying the card's bus width by the speed of its memory. If it uses DDR type RAM, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This figure is calculated by multiplying the total number of texture units 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 processed in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
