Compare any two graphics cards:
GeForce GT 240 GDDR5 vs Radeon HD 4770
IntroThe GeForce GT 240 GDDR5 comes with a GPU core clock speed of 550 MHz, and the 512 MB of GDDR5 memory is set to run at 850 MHz through a 128-bit bus. It also is made up of 96 SPUs, 32 TAUs, and 8 Raster Operation Units.Compare that to the Radeon HD 4770, which has core clock speeds of 750 MHz on the GPU, and 800 MHz on the 512 MB of GDDR5 RAM. It features 640(128x5) SPUs as well as 32 Texture Address Units and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe GeForce GT 240 GDDR5, in theory, should be a little bit faster than the Radeon HD 4770 overall. (explain)
Texel RateThe Radeon HD 4770 will be quite a bit (more or less 36%) more effective at AF than the GeForce GT 240 GDDR5. (explain)
Pixel RateThe Radeon HD 4770 is much (more or less 173%) better at FSAA than the GeForce GT 240 GDDR5, and capable of handling higher resolutions without slowing down too much. (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 within a second. It's calculated by multiplying the card's interface width by the speed of its memory. In the case of DDR memory, the result should be multiplied by 2 again. If 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, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied in one second. This is worked out by multiplying the total amount of texture units by the core speed of the chip. The higher the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second. Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly record to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as 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 of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
