Compare any two graphics cards:
GeForce GTX 580 3GB vs Radeon R9 380X
IntroThe GeForce GTX 580 3GB comes with a GPU clock speed of 772 MHz, and the 3072 MB of GDDR5 RAM runs at 1002 MHz through a 384-bit bus. It also is made up of 512 SPUs, 64 Texture Address Units, and 48 ROPs.Compare all that to the Radeon R9 380X, which features a GPU core clock speed of 970 MHz, and 4096 MB of GDDR5 RAM set to run at 1425 MHz through a 256-bit bus. It also features 2048 SPUs, 128 TAUs, and 32 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the GeForce GTX 580 3GB should be a little bit faster than the Radeon R9 380X in general. (explain)
Texel RateThe Radeon R9 380X will be quite a bit (about 151%) better at texture filtering than the GeForce GTX 580 3GB. (explain)
Pixel RateIf using high levels of AA is important to you, then the GeForce GTX 580 3GB is the winner, but not 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 information (measured in megabytes per second) that can be transported past the external memory interface in one second. It's worked out by multiplying the card's bus width by its memory clock speed. If it uses DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied in one second. This is worked out by multiplying the total texture units by the core clock speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly write to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
