Compare any two graphics cards:
GeForce GTX 560 Ti 448 vs Radeon R9 M390X
IntroThe GeForce GTX 560 Ti 448 comes with a clock frequency of 732 MHz and a GDDR5 memory speed of 900 MHz. It also uses a 320-bit bus, and uses a 40 nm design. It is made up of 448 SPUs, 56 Texture Address Units, and 40 ROPs.Compare all that to the Radeon R9 M390X, which has a core clock frequency of 723 MHz and a GDDR5 memory speed of 1250 MHz. It also features a 256-bit bus, and uses a 28 nm design. It is comprised of 2048 SPUs, 128 TAUs, and 32 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically, the Radeon R9 M390X should perform a small bit faster than the GeForce GTX 560 Ti 448 in general. (explain)
Texel RateThe Radeon R9 M390X will be quite a bit (more or less 126%) better at anisotropic filtering than the GeForce GTX 560 Ti 448. (explain)
Pixel RateIf using lots of anti-aliasing is important to you, then the GeForce GTX 560 Ti 448 is superior to the Radeon R9 M390X, 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: Memory bandwidth is the maximum amount of information (measured in MB per second) that can be transferred over the external memory interface in one second. It is calculated by multiplying the card's bus width by its memory speed. In the case of DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the better 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 number of texture map elements (texels) that are processed in one second. This figure is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The higher the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second. Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly write to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Render Output Units 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 output rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
