GeForce 9800 GTX+		70400 MB/sec
GeForce GT 440 1.5GB		43200 MB/sec
	Difference: 27200 (63%)

Texel Rate

The GeForce 9800 GTX+ will be quite a bit (about 231%) better at texture filtering than the GeForce GT 440 1.5GB. (explain)

GeForce 9800 GTX+		47232 Mtexels/sec
GeForce GT 440 1.5GB		14256 Mtexels/sec
	Difference: 32976 (231%)

Pixel Rate

If using a high resolution is important to you, then the GeForce GT 440 1.5GB is a better choice, and very much so. (explain)

GeForce GT 440 1.5GB		14256 Mpixels/sec
GeForce 9800 GTX+		11808 Mpixels/sec
	Difference: 2448 (21%)

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 (in units of MB per second) that can be transported over the external memory interface in a second. It's calculated by multiplying the interface width by its memory speed. If it uses DDR type memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster 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 figure is calculated by multiplying the total amount 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 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 card can possibly write to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
