Compare any two graphics cards:
GeForce GT 240 GDDR5 1GB vs GeForce GT 340 1GB
IntroThe GeForce GT 240 GDDR5 1GB features a clock frequency of 550 MHz and a GDDR5 memory frequency of 850 MHz. It also makes use of a 128-bit bus, and makes use of a 40 nm design. It features 96 SPUs, 32 TAUs, and 8 Raster Operation Units.Compare those specs to the GeForce GT 340 1GB, which features a core clock frequency of 550 MHz and a GDDR5 memory speed of 850 MHz. It also uses a 128-bit memory bus, and makes use of a 40 nm design. It features 96 SPUs, 32 Texture Address Units, and 8 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthBoth cards have exactly the same bandwidth, so theoretically they should perform the same. (explain)
Texel RateBoth cards have exactly the same texel fill rate, so in theory they should be equally good at at anisotropic filtering. (explain)Pixel RateBoth cards have exactly the same pixel fill rate, so theoretically they should be equally good at at anti-aliasing, and be able to handle the same screen resolutions. (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 largest amount of information (in units of MB per second) that can be transported past the external memory interface in a second. It is calculated by multiplying the card's bus width by its memory speed. If it uses DDR type memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher 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 texture map elements (texels) that can be applied in one second. This is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The better this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second. Pixel Rate: Pixel rate is the most pixels the video card can possibly record to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
