GeForce GT 440 1.5GB vs GeForce GT 440 3GB
Intro
The GeForce GT 440 1.5GB features a GPU core speed of 594 MHz, and the 1536 MB of GDDR3 memory is set to run at 900 MHz through a 192-bit bus. It also features 144 Stream Processors, 24 Texture Address Units, and 24 Raster Operation Units.Compare those specs to the GeForce GT 440 3GB, which has a GPU core clock speed of 594 MHz, and 3072 MB of GDDR3 RAM running at 900 MHz through a 192-bit bus. It also features 144 SPUs, 24 TAUs, and 24 Raster Operation Units.
Power Usage and Theoretical Benchmarks
Both cards have the same power consumption.Memory Bandwidth
Both cards have the exact same bandwidth, so theoretically they should have the same performance. (explain)
Texel Rate
Both cards have the exact same texel rate, so in theory they should be equally good at at anisotropic filtering. (explain)Pixel Rate
Both cards have the exact same pixel rate, so in theory they should perform equally good at at anti-aliasing, and be able to handle the same resolutions. (explain)
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.

Memory Bandwidth: Memory bandwidth is the max amount of information (counted in megabytes per second) that can be transferred past the external memory interface in one second. The number is worked out by multiplying the interface width by the speed of its memory. If it uses DDR memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and high resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed in one second. This number is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The better this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.
Pixel Rate: Pixel rate is the most pixels the video card could possibly write to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on lots of 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.
