Compare any two graphics cards:
GeForce 9800 GTX+ vs GeForce GTS 250 1GB
IntroThe GeForce 9800 GTX+ comes with a clock frequency of 738 MHz and a GDDR3 memory frequency of 1100 MHz. It also features a 256-bit bus, and makes use of a 55 nm design. It is made up of 128 SPUs, 64 Texture Address Units, and 16 Raster Operation Units.Compare that to the GeForce GTS 250 1GB, which has a GPU core clock speed of 738 MHz, and 1024 MB of GDDR3 RAM set to run at 1100 MHz through a 256-bit bus. It also features 128 Stream Processors, 64 TAUs, and 16 ROPs.

Power Usage and Theoretical BenchmarksBoth cards have the same power consumption.Memory BandwidthBoth cards have exactly the same memory bandwidth, so in theory they should perform the same. (explain)
Texel RateBoth cards have exactly the same texel rate, so in theory they should perform equally good at at anisotropic filtering. (explain)Pixel RateBoth cards have exactly the same pixel rate, so in theory they should be equally good at at FSAA, 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 max amount of data (counted in MB per second) that can be moved over the external memory interface in one second. It is worked out by multiplying the card's bus width by the speed of its memory. In the case of DDR type memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This number is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The higher this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second. Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly record to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
