GeForce GT 440 1.5GB vs GeForce GTX 260

Intro

Compare that to the GeForce GTX 260, which features GPU core 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 192 Stream Processors, 64 Texture Address Units, and 28 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 440 1.5GB		56 Watts
GeForce GTX 260		182 Watts
	Difference: 126 Watts (225%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 260 should perform quite a bit faster than the GeForce GT 440 1.5GB overall. (explain)

GeForce GTX 260		111888 MB/sec
GeForce GT 440 1.5GB		43200 MB/sec
	Difference: 68688 (159%)

Texel Rate

The GeForce GTX 260 should be a lot (approximately 159%) better at texture filtering than the GeForce GT 440 1.5GB. (explain)

GeForce GTX 260		36864 Mtexels/sec
GeForce GT 440 1.5GB		14256 Mtexels/sec
	Difference: 22608 (159%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GTX 260 is the winner, not by a very large margin though. (explain)

GeForce GTX 260		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: Bandwidth is the maximum amount of data (in units of MB per second) that can be transferred across the external memory interface in a second. The number is calculated by multiplying the card's bus width by the speed of its memory. If the card has DDR type RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed per second. This number is worked out by multiplying the total texture units by the core clock speed of the chip. The better the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

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