Compare any two graphics cards:
Radeon HD 6990 vs Radeon RX 560
IntroThe Radeon HD 6990 features a GPU core speed of 830 MHz, and the 2048 MB of GDDR5 RAM is set to run at 1250 MHz through a 256-bit bus. It also is comprised of 1536 SPUs, 96 TAUs, and 32 ROPs.Compare those specs to the Radeon RX 560, which uses a 14 nm design. AMD has clocked the core speed at 1175 MHz. The GDDR5 RAM works at a frequency of 1750 MHz on this particular card. It features 1024 SPUs as well as 64 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the Radeon HD 6990 is 179% faster than the Radeon RX 560 in general, due to its higher data rate. (explain)
Texel RateThe Radeon HD 6990 should be quite a bit (more or less 112%) better at anisotropic filtering than the Radeon RX 560. (explain)
Pixel RateThe Radeon HD 6990 is much (about 183%) better at FSAA than the Radeon RX 560, and also will 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. 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 information (in units of MB per second) that can be moved across the external memory interface in one second. It is calculated by multiplying the card's interface width by the speed of its memory. If it uses DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This number is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The better the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly record to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output 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.
