Compare any two graphics cards:
Geforce GTX 780 vs Radeon R9 390 8G
IntroThe Geforce GTX 780 uses a 28 nm design. nVidia has set the core frequency at 863 MHz. The GDDR5 memory works at a speed of 1502 MHz on this particular card. It features 2304 SPUs as well as 192 Texture Address Units and 48 ROPs.Compare all that to the Radeon R9 390 8G, which has a clock speed of 1000 MHz and a GDDR5 memory speed of 1500 MHz. It also uses a 512-bit bus, and uses a 28 nm design. It features 2560 SPUs, 160 Texture Address Units, and 64 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthAs far as performance goes, the Radeon R9 390 8G should theoretically be quite a bit superior to the Geforce GTX 780 overall. (explain)
Texel RateThe Geforce GTX 780 is just a bit (approximately 4%) more effective at anisotropic filtering than the Radeon R9 390 8G. (explain)
Pixel RateThe Radeon R9 390 8G is much (about 54%) more effective at FSAA than the Geforce GTX 780, and also able to handle higher screen resolutions while still performing well. (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 information (measured in MB per second) that can be moved past the external memory interface in one second. The number is worked out by multiplying the card's interface width by its memory speed. In the case of DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better 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 can be processed per second. This 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 handling 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 could possibly record to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Raster Operations Pipelines by the the core 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 quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
