Compare any two graphics cards:
Geforce GTX 690 vs Radeon HD 7790
IntroThe Geforce GTX 690 makes use of a 28 nm design. nVidia has clocked the core frequency at 915 MHz. The GDDR5 memory is set to run at a frequency of 1502 MHz on this particular card. It features 1536 SPUs as well as 128 Texture Address Units and 32 Rasterization Operator Units.
Compare all of that to the Radeon HD 7790, which comes with GPU clock speed of 1000 MHz, and 1024 MB of GDDR5 memory running at 1500 MHz through a 128-bit bus. It also is made up of 896 Stream Processors, 56 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
In theory, the Geforce GTX 690 should perform quite a bit faster than the Radeon HD 7790 overall. (explain)
Texel RateThe Geforce GTX 690 will be much (more or less 318%) more effective at texture filtering than the Radeon HD 7790. (explain)
Pixel RateThe Geforce GTX 690 should be quite a bit (approximately 266%) more effective at anti-aliasing than the Radeon HD 7790, and also should be able to handle higher 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.

Memory Bandwidth: Bandwidth is the max amount of data (in units of MB per second) that can be transported across the external memory interface in one second. It is calculated by multiplying the bus width by the speed of its memory. In the case of DDR type memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed 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 card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.
Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
