Compare any two graphics cards:
Radeon HD 6990 vs Radeon R9 380 2G
IntroThe Radeon HD 6990 has a clock speed of 830 MHz and a GDDR5 memory frequency of 1250 MHz. It also makes use of a 256-bit memory bus, and uses a 40 nm design. It is made up of 1536 SPUs, 96 TAUs, and 32 Raster Operation Units.Compare that to the Radeon R9 380 2G, which has a clock frequency of 970 MHz and a GDDR5 memory frequency of 1425 MHz. It also makes use of a 256-bit bus, and makes use of a 28 nm design. It features 1792 SPUs, 112 TAUs, and 32 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the Radeon HD 6990 should be 75% faster than the Radeon R9 380 2G overall, due to its higher bandwidth. (explain)
Texel RateThe Radeon HD 6990 will be a lot (about 47%) faster with regards to AF than the Radeon R9 380 2G. (explain)
Pixel RateIf using a high resolution is important to you, then the Radeon HD 6990 is superior to the Radeon R9 380 2G, and very much so. (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 largest amount of data (in units of MB per second) that can be moved across the external memory interface within a second. It's worked out by multiplying the interface width by the speed of its memory. If the card has DDR type memory, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied per second. This is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The higher this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second. Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly record to the local memory per 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 sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on many 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.
