Compare any two graphics cards:
GeForce GT 440 1.5GB vs GeForce GTX 285 2GB
IntroThe GeForce GT 440 1.5GB comes with a GPU core clock speed of 594 MHz, and the 1536 MB of GDDR3 memory runs at 900 MHz through a 192-bit bus. It also is made up of 144 SPUs, 24 Texture Address Units, and 24 Raster Operation Units.Compare all that to the GeForce GTX 285 2GB, which comes with GPU clock speed of 648 MHz, and 2048 MB of GDDR3 memory running at 1242 MHz through a 512-bit bus. It also features 240 SPUs, 80 TAUs, and 32 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthPerformance-wise, the GeForce GTX 285 2GB should in theory be much better than the GeForce GT 440 1.5GB in general. (explain)
Texel RateThe GeForce GTX 285 2GB will be quite a bit (approximately 264%) better at anisotropic filtering than the GeForce GT 440 1.5GB. (explain)
Pixel RateThe GeForce GTX 285 2GB is quite a bit (approximately 45%) better at anti-aliasing than the GeForce GT 440 1.5GB, and should be capable of handling higher resolutions without slowing down too much. (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

Display Specifications
Memory Bandwidth: Memory bandwidth is the maximum amount of data (counted in megabytes per second) that can be moved across the external memory interface in one second. It is calculated by multiplying the card's bus width by its memory clock speed. If the card has DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied in one second. This figure is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher this number, 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 maximum amount of pixels that the graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
