Compare any two graphics cards:
GeForce 8800 GTS (G92) vs GeForce GT 240 GDDR5 1GB
IntroThe GeForce 8800 GTS (G92) makes use of a 65 nm design. nVidia has clocked the core frequency at 650 MHz. The GDDR3 memory works at a frequency of 970 MHz on this particular card. It features 128 SPUs along with 64 Texture Address Units and 16 Rasterization Operator Units.Compare all of that to the GeForce GT 240 GDDR5 1GB, which comes with a core clock frequency of 550 MHz and a GDDR5 memory speed of 850 MHz. It also makes use of a 128-bit memory bus, and makes use of a 40 nm design. It is comprised of 96 SPUs, 32 TAUs, and 8 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe GeForce 8800 GTS (G92) should in theory perform a bit faster than the GeForce GT 240 GDDR5 1GB overall. (explain)
Texel RateThe GeForce 8800 GTS (G92) will be a lot (more or less 136%) more effective at texture filtering than the GeForce GT 240 GDDR5 1GB. (explain)
Pixel RateThe GeForce 8800 GTS (G92) should be much (more or less 136%) more effective at full screen anti-aliasing than the GeForce GT 240 GDDR5 1GB, and also able to handle higher resolutions better. (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 megabytes per second) that can be transferred past the external memory interface within a second. It is worked out by multiplying the card's bus width by the speed of its memory. If it uses DDR RAM, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This number is worked out by multiplying the total number of texture units of the card by the core 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 in one second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called 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 - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
