Compare any two graphics cards:
GeForce 8600 GT 256MB GDDR3 vs GeForce GT 440 1.5GB
IntroThe GeForce 8600 GT 256MB GDDR3 makes use of a 80 nm design. nVidia has set the core frequency at 540 MHz. The GDDR3 RAM is set to run at a frequency of 700 MHz on this specific model. It features 32 SPUs as well as 16 TAUs and 8 Rasterization Operator Units.Compare all of that to the GeForce GT 440 1.5GB, which comes with clock speeds of 594 MHz on the GPU, and 900 MHz on the 1536 MB of GDDR3 memory. It features 144 SPUs along with 24 Texture Address Units and 24 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe GeForce GT 440 1.5GB, in theory, should perform a lot faster than the GeForce 8600 GT 256MB GDDR3 overall. (explain)
Texel RateThe GeForce GT 440 1.5GB is quite a bit (more or less 65%) faster with regards to AF than the GeForce 8600 GT 256MB GDDR3. (explain)
Pixel RateIf using a high resolution is important to you, then the GeForce GT 440 1.5GB is a better choice, 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: Memory bandwidth is the maximum amount of information (in units of megabytes per second) that can be moved across the external memory interface in a second. The number is calculated by multiplying the card's interface width by its memory speed. If it uses DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher 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 texture map elements (texels) that can be processed per second. This number is worked out by multiplying the total texture units by the core clock speed of the chip. The better this number, the better the video 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 the video card can possibly write 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 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 many 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.
