Compare any two graphics cards:
Radeon HD 6990 vs Radeon RX 480
IntroThe Radeon HD 6990 comes with a GPU core speed of 830 MHz, and the 2048 MB of GDDR5 memory runs at 1250 MHz through a 256-bit bus. It also features 1536 SPUs, 96 TAUs, and 32 Raster Operation Units.Compare those specifications to the Radeon RX 480, which features a core clock frequency of 1120 MHz and a GDDR5 memory frequency of 2000 MHz. It also makes use of a 256-bit memory bus, and uses a 14 nm design. It is comprised of 2304 SPUs, 144 Texture Address Units, and 32 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthAs far as performance goes, the Radeon HD 6990 should in theory be much better than the Radeon RX 480 overall. (explain)
Texel RateThe Radeon RX 480 will be a little bit (approximately 1%) faster with regards to AF than the Radeon HD 6990. (explain)
Pixel RateThe Radeon HD 6990 is much (about 48%) more effective at full screen anti-aliasing than the Radeon RX 480, and also will be able to handle 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: Bandwidth is the max amount of information (in units of MB per second) that can be moved over the external memory interface in a second. It's worked out by multiplying the bus width by the speed of its memory. If the card has DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and high resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This figure is worked out by multiplying the total texture units by the core clock 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 in one second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs 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 rate is also dependant on quite a few 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.
