Compare any two graphics cards:
GeForce GTX Titan vs Radeon R9 390 8G
IntroThe GeForce GTX Titan has a clock frequency of 837 MHz and a GDDR5 memory speed of 1502 MHz. It also makes use of a 384-bit bus, and makes use of a 28 nm design. It features 2688 SPUs, 224 TAUs, and 48 ROPs.Compare all that to the Radeon R9 390 8G, which makes use of a 28 nm design. AMD has clocked the core frequency at 1000 MHz. The GDDR5 memory is set to run at a frequency of 1500 MHz on this specific model. It features 2560 SPUs along with 160 TAUs and 64 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthAs far as performance goes, the Radeon R9 390 8G should theoretically be much superior to the GeForce GTX Titan overall. (explain)
Texel RateThe GeForce GTX Titan will be a small bit (more or less 17%) better at anisotropic filtering than the Radeon R9 390 8G. (explain)
Pixel RateThe Radeon R9 390 8G should be much (about 59%) better at full screen anti-aliasing than the GeForce GTX Titan, and should be capable of handling higher resolutions better. (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 largest amount of information (counted in megabytes per second) that can be moved past the external memory interface in one second. The number is calculated by multiplying the card's bus width by its memory clock speed. In the case of DDR type memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one second. This number is calculated by multiplying the total amount of texture units of the card 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 per second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
