Compare any two graphics cards:
GeForce GTX 860M vs Radeon HD 6770 1GB
IntroThe GeForce GTX 860M makes use of a 28 nm design. nVidia has clocked the core speed at 797 MHz. The GDDR5 RAM runs at a frequency of 1000 MHz on this particular model. It features 1152 SPUs as well as 96 TAUs and 16 ROPs.Compare those specifications to the Radeon HD 6770 1GB, which uses a 40 nm design. AMD has clocked the core frequency at 900 MHz. The GDDR5 RAM is set to run at a speed of 1050 MHz on this specific model. It features 800 SPUs along with 40 TAUs and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the Radeon HD 6770 1GB should perform just a bit faster than the GeForce GTX 860M overall. (explain)
Texel RateThe GeForce GTX 860M should be quite a bit (about 113%) more effective at AF than the Radeon HD 6770 1GB. (explain)
Pixel RateIf running with lots of anti-aliasing is important to you, then the Radeon HD 6770 1GB is the winner, but only just. (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 past the external memory interface in one second. The number is worked out by multiplying the card's bus width by the speed of its memory. If it uses DDR memory, the result should be multiplied by 2 again. If 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 texture map elements (texels) that are applied per second. This figure is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The higher this number, the better the graphics 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 maximum number of pixels that the graphics card could possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Render Output Units 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 fill rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
