Compare any two graphics cards:
GeForce GTX 780 Ti vs Radeon HD 6990
IntroThe GeForce GTX 780 Ti makes use of a 28 nm design. nVidia has set the core speed at 875 MHz. The GDDR5 memory runs at a speed of 1750 MHz on this particular card. It features 2880 SPUs along with 240 TAUs and 48 Rasterization Operator Units.Compare all of that to the Radeon HD 6990, which has a clock frequency of 830 MHz and a GDDR5 memory speed of 1250 MHz. It also features a 256-bit memory bus, and makes use of a 40 nm design. It features 1536 SPUs, 96 TAUs, and 32 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the GeForce GTX 780 Ti is 5% faster than the Radeon HD 6990 overall, due to its higher data rate. (explain)
Texel RateThe GeForce GTX 780 Ti is a lot (more or less 32%) better at AF than the Radeon HD 6990. (explain)
Pixel RateThe Radeon HD 6990 will be quite a bit (approximately 26%) more effective at anti-aliasing than the GeForce GTX 780 Ti, and will be able to handle higher resolutions without losing too much performance. (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 maximum amount of data (measured in MB per second) that can be moved over the external memory interface in one second. The number is calculated by multiplying the interface width by the speed of its memory. If it uses DDR memory, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's 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 texture map elements (texels) that are applied per second. This is calculated by multiplying the total number of texture units by the core speed of the chip. The higher this number, the better the video 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 amount of pixels the graphics card can possibly record to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
