GeForce GT 440 3GB vs GeForce GTX 560

Intro

Compare those specs to the GeForce GTX 560, which makes use of a 40 nm design. nVidia has set the core speed at 810 MHz. The GDDR5 RAM works at a speed of 1001 MHz on this specific card. It features 336 SPUs along with 56 Texture Address Units and 32 ROPs.

GeForce GT 440 3GB		14256 Mtexels/sec
	Difference: 31104 (218%)

Pixel Rate

The GeForce GTX 560 will be quite a bit (approximately 82%) faster with regards to anti-aliasing than the GeForce GT 440 3GB, and also should be able to handle higher screen resolutions while still performing well. (explain)

GeForce GTX 560		25920 Mpixels/sec
GeForce GT 440 3GB		14256 Mpixels/sec
	Difference: 11664 (82%)

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 (in units of megabytes per second) that can be moved across the external memory interface in a second. It's worked out by multiplying the card's bus width by its memory speed. If the card has DDR type RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, the faster 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 amount of texture map elements (texels) that can be processed in one second. This figure is worked out by multiplying the total number of texture units by the core speed of the chip. The better this number, the better the video 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 write to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
