Compare any two graphics cards:
GeForce 8500 GT vs GeForce GT 440 3GB
IntroThe GeForce 8500 GT uses a 80 nm design. nVidia has set the core frequency at 450 MHz. The DDR2 memory is set to run at a speed of 400 MHz on this specific card. It features 16 SPUs as well as 8 Texture Address Units and 4 Rasterization Operator Units.Compare that to the GeForce GT 440 3GB, which has a core clock speed of 594 MHz and a GDDR3 memory frequency of 900 MHz. It also features a 192-bit bus, and uses a 40 nm design. It is made up of 144 SPUs, 24 Texture Address Units, and 24 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically, the GeForce GT 440 3GB should be much faster than the GeForce 8500 GT overall. (explain)
Texel RateThe GeForce GT 440 3GB should be quite a bit (more or less 296%) faster with regards to anisotropic filtering than the GeForce 8500 GT. (explain)
Pixel RateIf using high levels of AA is important to you, then the GeForce GT 440 3GB is superior to the GeForce 8500 GT, by a large margin. (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: Bandwidth is the max amount of data (counted in MB per second) that can be transferred across the external memory interface in one second. It is worked out by multiplying the card's interface width by its memory speed. If the card has DDR type memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the faster 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 number of texture map elements (texels) that are applied per second. This figure is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The higher 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 maximum number of pixels the video card could possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of ROPs by the the core 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 is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
