Compare any two graphics cards:
Geforce GTX 670 vs Radeon HD 6990
IntroThe Geforce GTX 670 features a GPU clock speed of 915 MHz, and the 2048 MB of GDDR5 RAM runs at 1500 MHz through a 256-bit bus. It also features 1344 SPUs, 112 Texture Address Units, and 32 Raster Operation Units.Compare those specifications to the Radeon HD 6990, which has a clock speed of 830 MHz and a GDDR5 memory frequency of 1250 MHz. It also features a 256-bit memory bus, and uses a 40 nm design. It features 1536 SPUs, 96 TAUs, and 32 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe Radeon HD 6990 should theoretically perform quite a bit faster than the Geforce GTX 670 in general. (explain)
Texel RateThe Radeon HD 6990 is a lot (more or less 56%) better at texture filtering than the Geforce GTX 670. (explain)
Pixel RateIf running with high levels of AA is important to you, then the Radeon HD 6990 is a better choice, 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: Bandwidth is the max amount of data (measured in megabytes per second) that can be transferred past the external memory interface in one second. The number is worked out by multiplying the card's bus width by its memory clock speed. If the card has DDR memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed in one second. This is calculated by multiplying the total number of texture units by the core speed of the chip. The higher the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second. Pixel Rate: Pixel rate is the most pixels the graphics card can possibly write to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - aka 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 maximum fill rate.
