Compare any two graphics cards:
GeForce 8600 GT 1GB DDR2 vs GeForce GT 440 3GB
IntroThe GeForce 8600 GT 1GB DDR2 comes with a core clock speed of 540 MHz and a DDR2 memory frequency of 400 MHz. It also uses a 128-bit memory bus, and uses a 80 nm design. It is comprised of 32 SPUs, 16 TAUs, and 8 ROPs.Compare those specs to the GeForce GT 440 3GB, which makes use of a 40 nm design. nVidia has clocked the core frequency at 594 MHz. The GDDR3 RAM runs at a frequency of 900 MHz on this particular card. It features 144 SPUs along with 24 TAUs and 24 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the GeForce GT 440 3GB should be 238% faster than the GeForce 8600 GT 1GB DDR2 overall, due to its greater data rate. (explain)
Texel RateThe GeForce GT 440 3GB should be much (approximately 65%) faster with regards to texture filtering than the GeForce 8600 GT 1GB DDR2. (explain)
Pixel RateThe GeForce GT 440 3GB should be much (about 230%) faster with regards to anti-aliasing than the GeForce 8600 GT 1GB DDR2, and should be able to handle 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: Bandwidth is the max amount of data (counted in MB per second) that can be moved across the external memory interface in a second. The number is worked out by multiplying the bus width by its memory clock speed. In the case of DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This figure is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Render Output Units by the the core 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 is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
