Compare any two graphics cards:
GeForce GTX 480 vs Radeon R9 280X
IntroThe GeForce GTX 480 has a GPU clock speed of 700 MHz, and the 1536 MB of GDDR5 memory is set to run at 924 MHz through a 384-bit bus. It also features 480 SPUs, 60 Texture Address Units, and 48 ROPs.Compare all of that to the Radeon R9 280X, which comes with a GPU core clock speed of 850 MHz, and 3072 MB of GDDR5 RAM set to run at 1500 MHz through a 384-bit bus. It also is comprised of 2048 SPUs, 128 TAUs, and 32 ROPs.

Power Usage and Theoretical BenchmarksBoth cards have the same power consumption.Memory BandwidthThe Radeon R9 280X should theoretically be a lot faster than the GeForce GTX 480 in general. (explain)
Texel RateThe Radeon R9 280X should be a lot (more or less 159%) more effective at anisotropic filtering than the GeForce GTX 480. (explain)
Pixel RateIf running with a high screen resolution is important to you, then the GeForce GTX 480 is the winner, by far. (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 data (in units of megabytes per second) that can be transported across the external memory interface in a second. It is worked out by multiplying the interface width by its memory speed. In the case of DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better 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 texture map elements (texels) that are applied per second. This figure is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The better the texel rate, the better the graphics 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 chip could possibly write to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
