Compare any two graphics cards:
Geforce GTX 1080 Ti vs Radeon HD 7990
IntroThe Geforce GTX 1080 Ti has a core clock speed of 1480 MHz and a GDDR5X memory frequency of 1376 MHz. It also makes use of a 352-bit bus, and makes use of a 16 nm design. It is made up of 3584 SPUs, 224 Texture Address Units, and 88 Raster Operation Units.Compare those specs to the Radeon HD 7990, which features a core clock speed of 950 MHz and a GDDR5 memory frequency of 1500 MHz. It also uses a 384-bit bus, and uses a 28 nm design. It is made up of 2048 SPUs, 128 Texture Address Units, and 32 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically, the Radeon HD 7990 should perform a little bit faster than the Geforce GTX 1080 Ti overall. (explain)
Texel RateThe Geforce GTX 1080 Ti will be quite a bit (about 36%) more effective at texture filtering than the Radeon HD 7990. (explain)
Pixel RateIf running with high levels of AA is important to you, then the Geforce GTX 1080 Ti is superior to the Radeon HD 7990, 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. 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: Bandwidth is the max amount of data (measured in MB per second) that can be moved across the external memory interface within a second. It's calculated by multiplying the card's bus width by its memory speed. In the case of DDR memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied in one second. This is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The higher this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly write to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
