Compare any two graphics cards:
GeForce GTX 280 vs Radeon R9 285
IntroThe GeForce GTX 280 has a core clock speed of 602 MHz and a GDDR3 memory frequency of 1107 MHz. It also features a 512-bit bus, and uses a 65 nm design. It features 240 SPUs, 80 Texture Address Units, and 32 ROPs.Compare those specs to the Radeon R9 285, which comes with a clock speed of 918 MHz and a GDDR5 memory speed of 1375 MHz. It also uses a 256-bit bus, and uses a 28 nm design. It is made up of 1792 SPUs, 112 Texture Address Units, and 32 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the Radeon R9 285 will be 24% faster than the GeForce GTX 280 overall, because of its greater bandwidth. (explain)
Texel RateThe Radeon R9 285 will be quite a bit (about 113%) more effective at texture filtering than the GeForce GTX 280. (explain)
Pixel RateThe Radeon R9 285 will be much (about 52%) better at FSAA than the GeForce GTX 280, and also capable of handling higher screen resolutions better. (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 (in units of MB per second) that can be transported over the external memory interface within a second. It's worked out by multiplying the bus width by its memory clock speed. If the card has DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second. Pixel Rate: Pixel rate is the most pixels the video card can possibly record to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number 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 outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
