Compare any two graphics cards:
GeForce 8600 GT 256MB GDDR3 vs GeForce GT 440 3GB
IntroThe GeForce 8600 GT 256MB GDDR3 uses a 80 nm design. nVidia has clocked the core frequency at 540 MHz. The GDDR3 RAM works at a speed of 700 MHz on this particular card. It features 32 SPUs as well as 16 Texture Address Units and 8 Rasterization Operator Units.Compare all of that to the GeForce GT 440 3GB, which has clock speeds of 594 MHz on the GPU, and 900 MHz on the 3072 MB of GDDR3 memory. It features 144 SPUs as well as 24 TAUs and 24 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the GeForce GT 440 3GB should be a lot faster than the GeForce 8600 GT 256MB GDDR3 overall. (explain)
Texel RateThe GeForce GT 440 3GB should be quite a bit (more or less 65%) more effective at texture filtering than the GeForce 8600 GT 256MB GDDR3. (explain)
Pixel RateThe GeForce GT 440 3GB should be much (about 230%) better at full screen anti-aliasing than the GeForce 8600 GT 256MB GDDR3, and should be able to handle higher screen resolutions while still performing well. (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 information (measured in megabytes per second) that can be transported across the external memory interface in one second. It is calculated by multiplying the card's bus width by the speed of its memory. If the card has DDR RAM, it must 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 can be applied per second. This is worked out by multiplying the total texture units of the card by the core speed of the chip. The better the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly write to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
