Compare any two graphics cards:
GeForce GT 240 GDDR5 1GB vs Radeon R9 280
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 SPUs, 32 Texture Address Units, and 8 Raster Operation Units.Compare those specifications to the Radeon R9 280, which makes use of a 28 nm design. AMD has set the core speed at 933 MHz. The GDDR5 RAM runs at a frequency of 1250 MHz on this card. It features 1792 SPUs along with 112 Texture Address Units and 32 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the Radeon R9 280 should be 341% faster than the GeForce GT 240 GDDR5 1GB in general, because of its greater data rate. (explain)
Texel RateThe Radeon R9 280 should be much (approximately 494%) more effective at texture filtering than the GeForce GT 240 GDDR5 1GB. (explain)
Pixel RateIf running with a high resolution is important to you, then the Radeon R9 280 is the winner, 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 largest amount of data (in units of MB per second) that can be transferred over the external memory interface within a second. The number is worked out by multiplying the card's bus width by the speed of its memory. In the case of DDR type RAM, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster 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 figure is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The higher this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can 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 clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
