Compare any two graphics cards:
GeForce GT 240 GDDR5 1GB vs Radeon HD 7870 XT
IntroThe GeForce GT 240 GDDR5 1GB has clock speeds of 550 MHz on the GPU, and 850 MHz on the 1024 MB of GDDR5 RAM. It features 96 SPUs along with 32 Texture Address Units and 8 ROPs.Compare those specs to the Radeon HD 7870 XT, which features core speeds of 925 MHz on the GPU, and 1500 MHz on the 2048 MB of GDDR5 RAM. It features 1536 SPUs along with 96 Texture Address Units and 32 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthPerformance-wise, the Radeon HD 7870 XT should theoretically be quite a bit superior to the GeForce GT 240 GDDR5 1GB overall. (explain)
Texel RateThe Radeon HD 7870 XT is much (approximately 405%) better at anisotropic filtering than the GeForce GT 240 GDDR5 1GB. (explain)
Pixel RateIf running with a high resolution is important to you, then the Radeon HD 7870 XT is superior to the GeForce GT 240 GDDR5 1GB, and very much so. (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 max amount of information (measured in megabytes per second) that can be transferred past the external memory interface in a second. The number is calculated by multiplying the card's interface width by the speed of its memory. In the case of DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The higher the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second. Pixel Rate: Pixel rate is the most pixels the video card can possibly record to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
