GeForce GT 320 vs GeForce GT 440 3GB

Intro

Compare that to the GeForce GT 440 3GB, which has GPU clock speed of 594 MHz, and 3072 MB of GDDR3 memory set to run at 900 MHz through a 192-bit bus. It also is comprised of 144 SPUs, 24 Texture Address Units, and 24 Raster Operation Units.

GeForce GT 320		43 Watts
GeForce GT 440 3GB		56 Watts
	Difference: 13 Watts (30%)

Memory Bandwidth

Theoretically speaking, the GeForce GT 440 3GB will be 71% faster than the GeForce GT 320 in general, because of its greater bandwidth. (explain)

GeForce GT 440 3GB		43200 MB/sec
GeForce GT 320		25280 MB/sec
	Difference: 17920 (71%)

Texel Rate

The GeForce GT 440 3GB is a small bit (about 10%) more effective at anisotropic filtering than the GeForce GT 320. (explain)

GeForce GT 440 3GB		14256 Mtexels/sec
GeForce GT 320		12960 Mtexels/sec
	Difference: 1296 (10%)

Pixel Rate

The GeForce GT 440 3GB is much (more or less 230%) better at full screen anti-aliasing than the GeForce GT 320, and capable of handling higher resolutions without slowing down too much. (explain)

GeForce GT 440 3GB		14256 Mpixels/sec
GeForce GT 320		4320 Mpixels/sec
	Difference: 9936 (230%)

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 transferred past the external memory interface in one second. The number is calculated by multiplying the bus width by the speed of its memory. In the case of DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, 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 can be applied per second. This is calculated by multiplying the total 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 processed in a second.

Pixel Rate: Pixel rate is the most pixels the video card could possibly write to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called 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 of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
