Compare any two graphics cards:
GeForce GTX 850M vs Radeon HD 7950 3GB
IntroThe GeForce GTX 850M makes use of a 28 nm design. nVidia has set the core speed at 876 MHz. The DDR3 RAM runs at a speed of 1000 MHz on this particular model. It features 640 SPUs as well as 40 TAUs and 16 ROPs.Compare all of that to the Radeon HD 7950 3GB, which has GPU clock speed of 800 MHz, and 3072 MB of GDDR5 RAM running at 1250 MHz through a 384-bit bus. It also features 1792 Stream Processors, 112 Texture Address Units, and 32 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the Radeon HD 7950 3GB should perform much faster than the GeForce GTX 850M in general. (explain)
Texel RateThe Radeon HD 7950 3GB is quite a bit (about 156%) better at anisotropic filtering than the GeForce GTX 850M. (explain)
Pixel RateThe Radeon HD 7950 3GB should be a lot (about 83%) faster with regards to anti-aliasing than the GeForce GTX 850M, and also will be capable of handling 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. Price Comparison

Display Specifications
Memory Bandwidth: Bandwidth is the max amount of information (counted in MB per second) that can be transferred over the external memory interface in one second. It is calculated by multiplying the card's bus width by its memory clock speed. If it uses DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied per second. This number is calculated by multiplying the total amount of texture units by the core speed of the chip. The higher the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
