GeForce GT 440 1.5GB vs GeForce GTX 260 Core 216

Intro

Compare all of that to the GeForce GTX 260 Core 216, which has a GPU core clock speed of 576 MHz, and 896 MB of GDDR3 memory running at 999 MHz through a 448-bit bus. It also is made up of 216 Stream Processors, 72 Texture Address Units, and 28 Raster Operation Units.

GeForce GT 440 1.5GB		14256 Mtexels/sec
	Difference: 27216 (191%)

Pixel Rate

The GeForce GTX 260 Core 216 is a bit (about 13%) more effective at anti-aliasing than the GeForce GT 440 1.5GB, and also will be capable of handling higher resolutions more effectively. (explain)

GeForce GTX 260 Core 216		16128 Mpixels/sec
GeForce GT 440 1.5GB		14256 Mpixels/sec
	Difference: 1872 (13%)

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 largest amount of data (measured in megabytes per second) that can be transported past the external memory interface in one second. It's worked out by multiplying the card's bus width by its memory speed. In the case of DDR RAM, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This figure is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The higher the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly record to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of ROPs by the the core speed of the card. 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 is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
