Compare any two graphics cards:
GeForce GTX 580 3GB vs Radeon R9 280
IntroThe GeForce GTX 580 3GB features a GPU core speed of 772 MHz, and the 3072 MB of GDDR5 RAM runs at 1002 MHz through a 384-bit bus. It also features 512 SPUs, 64 TAUs, and 48 Raster Operation Units.Compare those specifications to the Radeon R9 280, which comes with GPU clock speed of 933 MHz, and 3072 MB of GDDR5 memory set to run at 1250 MHz through a 384-bit bus. It also is comprised of 1792 Stream Processors, 112 TAUs, and 32 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthAs far as performance goes, the Radeon R9 280 should theoretically be quite a bit superior to the GeForce GTX 580 3GB overall. (explain)
Texel RateThe Radeon R9 280 will be much (about 111%) better at texture filtering than the GeForce GTX 580 3GB. (explain)
Pixel RateIf running with a high screen resolution is important to you, then the GeForce GTX 580 3GB is a better choice, by a large margin. (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 data (measured in MB per second) that can be moved past the external memory interface within a second. The number is worked out by multiplying the bus width by its memory clock speed. In the case of DDR type memory, it must be multiplied by 2 once 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 AA, HDR and high resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied in one second. This number is calculated by multiplying the total number of texture units by the core speed of the chip. The better this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second. Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
