Compare any two graphics cards:
GeForce GTX Titan Black vs Radeon R9 390 8G
IntroThe GeForce GTX Titan Black comes with a core clock frequency of 889 MHz and a GDDR5 memory frequency of 1750 MHz. It also makes use of a 384-bit bus, and uses a 28 nm design. It is comprised of 2880 SPUs, 240 Texture Address Units, and 48 Raster Operation Units.Compare all that to the Radeon R9 390 8G, which has clock speeds of 1000 MHz on the GPU, and 1500 MHz on the 8192 MB of GDDR5 RAM. It features 2560 SPUs along with 160 Texture Address Units and 64 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically, the Radeon R9 390 8G should be just a bit faster than the GeForce GTX Titan Black overall. (explain)
Texel RateThe GeForce GTX Titan Black should be quite a bit (about 33%) faster with regards to texture filtering than the Radeon R9 390 8G. (explain)
Pixel RateIf running with high levels of AA is important to you, then the Radeon R9 390 8G is the winner, 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: Bandwidth is the maximum amount of data (in units of MB per second) that can be transferred 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 type memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher 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 number of texture map elements (texels) that can be processed in one second. This is calculated by multiplying the total texture units by the core speed of the chip. The higher this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly record to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
