Compare any two graphics cards:
GeForce 8800 GT 256MB vs GeForce GT 440 3GB
IntroThe GeForce 8800 GT 256MB comes with core speeds of 600 MHz on the GPU, and 700 MHz on the 256 MB of GDDR3 RAM. It features 112 SPUs as well as 56 TAUs and 16 Rasterization Operator Units.Compare that to the GeForce GT 440 3GB, which features clock speeds of 594 MHz on the GPU, and 900 MHz on the 3072 MB of GDDR3 memory. It features 144 SPUs along with 24 TAUs and 24 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthPerformance-wise, the GeForce 8800 GT 256MB should theoretically be a small bit better than the GeForce GT 440 3GB in general. (explain)
Texel RateThe GeForce 8800 GT 256MB will be much (approximately 136%) more effective at AF than the GeForce GT 440 3GB. (explain)
Pixel RateIf using a high resolution is important to you, then the GeForce GT 440 3GB is the winner, 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

Display Specifications
Memory Bandwidth: Memory bandwidth is the largest amount of data (measured in megabytes per second) that can be transferred over the external memory interface in one second. It's worked out by multiplying the card's interface width by its memory clock speed. If the card has DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per second. This figure is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The higher this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second. Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
