Compare any two graphics cards:
GeForce GT 240 GDDR5 1GB vs GeForce GT 340 1GB
IntroThe GeForce GT 240 GDDR5 1GB comes with a GPU clock speed of 550 MHz, and the 1024 MB of GDDR5 RAM runs at 850 MHz through a 128-bit bus. It also is comprised of 96 Stream Processors, 32 Texture Address Units, and 8 Raster Operation Units.Compare all that to the GeForce GT 340 1GB, which features a GPU core clock speed of 550 MHz, and 1024 MB of GDDR5 memory running at 850 MHz through a 128-bit bus. It also is made up of 96 Stream Processors, 32 Texture Address Units, and 8 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthBoth cards have the exact same bandwidth, so in theory they should perform exactly the same. (explain)
Texel RateBoth cards have the exact same texel rate, so in theory they should perform equally good at at AF. (explain)Pixel RateBoth cards have the exact same pixel fill rate, so in theory they should be equally good at at AA, and be able to handle the same 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: Memory bandwidth is the largest amount of information (in units of MB per second) that can be transferred past the external memory interface within a second. It's calculated by multiplying the card's interface width by its memory clock speed. If it uses DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed in one 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 graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second. Pixel Rate: Pixel rate is the most pixels the graphics card could possibly write to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
