GeForce GT 230		38400 MB/sec
	Difference: 4800 (13%)

Texel Rate

The GeForce GT 440 1.5GB will be quite a bit (approximately 62%) faster with regards to texture filtering than the GeForce GT 230. (explain)

GeForce GT 440 1.5GB		14256 Mtexels/sec
GeForce GT 230		8800 Mtexels/sec
	Difference: 5456 (62%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce GT 440 1.5GB is the winner, by far. (explain)

GeForce GT 440 1.5GB		14256 Mpixels/sec
GeForce GT 230		4400 Mpixels/sec
	Difference: 9856 (224%)

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 maximum amount of information (measured in MB per second) that can be moved over the external memory interface in a second. It's worked out by multiplying the card's interface width by the speed of its memory. In the case of DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better 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 are processed in one second. This number is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The better the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly record to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
