Compare any two graphics cards:
GeForce GTX 870M vs Radeon HD 6750 1GB
IntroThe GeForce GTX 870M features a clock frequency of 941 MHz and a GDDR5 memory speed of 1000 MHz. It also features a 192-bit bus, and uses a 28 nm design. It features 1344 SPUs, 112 TAUs, and 24 Raster Operation Units.Compare those specifications to the Radeon HD 6750 1GB, which has a core clock speed of 725 MHz and a GDDR5 memory speed of 1000 MHz. It also uses a 128-bit bus, and makes use of a 40 nm design. It is made up of 720 SPUs, 36 TAUs, and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthPerformance-wise, the GeForce GTX 870M should theoretically be much better than the Radeon HD 6750 1GB overall. (explain)
Texel RateThe GeForce GTX 870M will be much (about 304%) more effective at AF than the Radeon HD 6750 1GB. (explain)
Pixel RateIf running with a high resolution is important to you, then the GeForce GTX 870M is superior to the Radeon HD 6750 1GB, 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: Memory bandwidth is the maximum amount of information (in units of MB per second) that can be transferred past the external memory interface within a second. The number is calculated by multiplying the card's bus width by its memory clock speed. In the case of DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This number is worked out by multiplying the total number 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 texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly record to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
