Compare any two graphics cards:
GeForce 8600 GT 256MB DDR2 vs GeForce GT 440 1.5GB
IntroThe GeForce 8600 GT 256MB DDR2 comes with core clock speeds of 540 MHz on the GPU, and 400 MHz on the 256 MB of DDR2 RAM. It features 32 SPUs as well as 16 Texture Address Units and 8 Rasterization Operator Units.Compare that to the GeForce GT 440 1.5GB, which features GPU clock speed of 594 MHz, and 1536 MB of GDDR3 RAM set to run at 900 MHz through a 192-bit bus. It also is made up of 144 Stream Processors, 24 Texture Address Units, and 24 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the GeForce GT 440 1.5GB should perform much faster than the GeForce 8600 GT 256MB DDR2 in general. (explain)
Texel RateThe GeForce GT 440 1.5GB should be much (more or less 65%) faster with regards to texture filtering than the GeForce 8600 GT 256MB DDR2. (explain)
Pixel RateIf using a high screen resolution is important to you, then the GeForce GT 440 1.5GB is superior to the GeForce 8600 GT 256MB DDR2, 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 information (measured in megabytes per second) that can be moved past the external memory interface in a second. It's worked out by multiplying the bus width by its memory speed. In the case of DDR RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster 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 texture map elements (texels) that are applied per second. This number is calculated by multiplying the total number of texture units by the core clock speed of the chip. The better this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second. Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly record to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
