Compare any two graphics cards:
GeForce GTX 460 SE vs Radeon HD 6790
IntroThe GeForce GTX 460 SE features a GPU clock speed of 650 MHz, and the 1024 MB of GDDR5 memory runs at 850 MHz through a 256-bit bus. It also features 288 SPUs, 48 TAUs, and 32 ROPs.Compare that to the Radeon HD 6790, which has core speeds of 840 MHz on the GPU, and 1050 MHz on the 1024 MB of GDDR5 RAM. It features 800 SPUs along with 40 Texture Address Units and 16 ROPs.

Power Usage and Theoretical BenchmarksBoth cards have the same power consumption.Memory BandwidthAs far as performance goes, the Radeon HD 6790 should in theory be quite a bit better than the GeForce GTX 460 SE overall. (explain)
Texel RateThe Radeon HD 6790 is just a bit (approximately 8%) more effective at anisotropic filtering than the GeForce GTX 460 SE. (explain)
Pixel RateThe GeForce GTX 460 SE should be quite a bit (more or less 55%) better at FSAA than the Radeon HD 6790, and also able to handle higher screen 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. Price Comparison

Display Specifications
Memory Bandwidth: Memory bandwidth is the max amount of information (counted in megabytes per second) that can be moved across the external memory interface in one second. It is calculated by multiplying the card's bus width by the speed of its memory. In the case of DDR RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. 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 amount of texture map elements (texels) that can be processed per second. This number is worked out by multiplying the total texture units of the card by the core speed of the chip. The higher the texel rate, the better the graphics 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 number of pixels that the graphics chip can possibly record to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
