Compare any two graphics cards:
GeForce GTX 560 Ti 448 vs Radeon HD 7990
IntroThe GeForce GTX 560 Ti 448 comes with a clock frequency of 732 MHz and a GDDR5 memory speed of 900 MHz. It also uses a 320-bit memory bus, and uses a 40 nm design. It is comprised of 448 SPUs, 56 Texture Address Units, and 40 Raster Operation Units.Compare all of that to the Radeon HD 7990, which features a clock frequency of 950 MHz and a GDDR5 memory speed of 1500 MHz. It also uses a 384-bit bus, and makes use of a 28 nm design. It features 2048 SPUs, 128 TAUs, and 32 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the Radeon HD 7990 will be 300% faster than the GeForce GTX 560 Ti 448 overall, because of its greater data rate. (explain)
Texel RateThe Radeon HD 7990 is quite a bit (more or less 493%) more effective at anisotropic filtering than the GeForce GTX 560 Ti 448. (explain)
Pixel RateIf using lots of anti-aliasing is important to you, then the Radeon HD 7990 is superior to the GeForce GTX 560 Ti 448, 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: Memory bandwidth is the maximum amount of data (measured in megabytes per second) that can be transported over the external memory interface in a second. The number is calculated by multiplying the card's bus width by its memory speed. In the case of DDR memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied per second. This is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second. Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly record to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs by the clock 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 also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
