Compare any two graphics cards:
GeForce GTX 880M vs Radeon HD 6790
IntroThe GeForce GTX 880M comes with a core clock frequency of 954 MHz and a GDDR5 memory speed of 1000 MHz. It also makes use of a 256-bit bus, and makes use of a 28 nm design. It is made up of 1536 SPUs, 128 TAUs, and 32 ROPs.Compare those specs to the Radeon HD 6790, which has a clock speed of 840 MHz and a GDDR5 memory frequency of 1050 MHz. It also uses a 256-bit memory bus, and makes use of a 40 nm design. It is comprised of 800 SPUs, 40 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthPerformance-wise, the Radeon HD 6790 should in theory be a little bit superior to the GeForce GTX 880M overall. (explain)
Texel RateThe GeForce GTX 880M should be much (more or less 263%) better at AF than the Radeon HD 6790. (explain)
Pixel RateIf using high levels of AA is important to you, then the GeForce GTX 880M is the winner, by far. (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: Bandwidth is the max amount of information (measured in MB per second) that can be moved across the external memory interface within a second. It is worked out by multiplying the card's interface 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 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed per second. This number is worked out by multiplying the total number of texture units by the core speed of the chip. The better the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second. Pixel Rate: Pixel rate is the most pixels the graphics card could 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 colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
