Compare any two graphics cards:
GeForce GTX Titan X vs Radeon HD 7990
IntroThe GeForce GTX Titan X has a clock frequency of 1000 MHz and a GDDR5 memory speed of 1750 MHz. It also features a 384-bit bus, and makes use of a 28 nm design. It is made up of 3072 SPUs, 192 TAUs, and 96 Raster Operation Units.Compare those specifications to the Radeon HD 7990, which uses a 28 nm design. AMD has set the core frequency at 950 MHz. The GDDR5 memory runs at a frequency of 1500 MHz on this particular model. It features 2048 SPUs as well as 128 Texture Address Units and 32 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthPerformance-wise, the Radeon HD 7990 should theoretically be quite a bit superior to the GeForce GTX Titan X in general. (explain)
Texel RateThe Radeon HD 7990 is much (approximately 27%) better at texture filtering than the GeForce GTX Titan X. (explain)
Pixel RateThe GeForce GTX Titan X is much (approximately 58%) more effective at AA than the Radeon HD 7990, and capable of handling higher screen 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. One or more cards in this comparison are multi-core. This means that their bandwidth, texel and pixel rates are theoretically doubled - this does not mean the card will actually perform twice as fast, but only that it should in theory be able to. Actual game benchmarks will give a more accurate idea of what it's capable of. Price Comparison

Display Specifications
Memory Bandwidth: Memory bandwidth is the largest amount of information (in units of MB per second) that can be moved across the external memory interface in a second. It is calculated by multiplying the card's bus width by its memory clock speed. If the card has DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed per second. This figure is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The better this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second. Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly record to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
