Compare any two graphics cards:
GeForce GTX 980 Ti vs Radeon R9 M390X
IntroThe GeForce GTX 980 Ti makes use of a 28 nm design. nVidia has set the core frequency at 1000 MHz. The GDDR5 RAM runs at a frequency of 1750 MHz on this model. It features 2816 SPUs along with 176 TAUs and 96 Rasterization Operator Units.Compare that to the Radeon R9 M390X, which uses a 28 nm design. AMD has set the core frequency at 723 MHz. The GDDR5 memory is set to run at a frequency of 1250 MHz on this specific model. It features 2048 SPUs as well as 128 TAUs and 32 Rasterization Operator Units.
Display Graphs
Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the GeForce GTX 980 Ti will be 110% quicker than the Radeon R9 M390X in general, because of its higher data rate. (explain)
Texel RateThe GeForce GTX 980 Ti will be much (about 90%) better at anisotropic filtering than the Radeon R9 M390X. (explain)
Pixel RateThe GeForce GTX 980 Ti is quite a bit (approximately 315%) better at FSAA than the Radeon R9 M390X, and also will be able to handle higher resolutions more effectively. (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 (measured in megabytes per second) that can be moved across the external memory interface in a second. The number is calculated by multiplying the interface width by the speed of its memory. If it uses DDR type memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster 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 processed in one second. This is calculated by multiplying the total texture units of the card by the core speed of the chip. The higher this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second. Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
