Compare any two graphics cards:
GeForce GT 430 vs GeForce GT 440 3GB
IntroThe GeForce GT 430 uses a 40 nm design. nVidia has set the core frequency at 700 MHz. The GDDR3 memory is set to run at a frequency of 900 MHz on this particular model. It features 96 SPUs along with 16 TAUs and 4 Rasterization Operator Units.Compare that to the GeForce GT 440 3GB, which uses a 40 nm design. nVidia has set the core speed at 594 MHz. The GDDR3 memory runs at a frequency of 900 MHz on this specific card. It features 144 SPUs along with 24 TAUs and 24 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the GeForce GT 440 3GB will be 50% quicker than the GeForce GT 430 overall, because of its greater data rate. (explain)
Texel RateThe GeForce GT 440 3GB should be much (about 27%) more effective at AF than the GeForce GT 430. (explain)
Pixel RateIf running with a high screen resolution is important to you, then the GeForce GT 440 3GB is a better choice, by far. (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. Price Comparison

Memory Bandwidth: Bandwidth is the max amount of information (counted in MB per second) that can be transferred over the external memory interface in a second. It's worked out by multiplying the bus width by the speed of its memory. In the case of DDR type RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied per second. This figure is calculated 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 video 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 that the graphics chip can possibly record to the 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 - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
