Compare any two graphics cards:
GeForce GTX 850M vs Radeon HD 5570
IntroThe GeForce GTX 850M comes with clock speeds of 876 MHz on the GPU, and 1000 MHz on the 2048 MB of DDR3 memory. It features 640 SPUs as well as 40 Texture Address Units and 16 ROPs.Compare all that to the Radeon HD 5570, which makes use of a 40 nm design. AMD has clocked the core frequency at 650 MHz. The DDR3 RAM runs at a frequency of 900 MHz on this specific card. It features 400(80x5) SPUs along with 20 TAUs and 8 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthAs far as performance goes, the GeForce GTX 850M should in theory be a bit better than the Radeon HD 5570 overall. (explain)
Texel RateThe GeForce GTX 850M should be much (approximately 170%) faster with regards to texture filtering than the Radeon HD 5570. (explain)
Pixel RateThe GeForce GTX 850M should be much (about 170%) more effective at FSAA than the Radeon HD 5570, and should be capable of handling higher resolutions more effectively. (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 megabytes per second) that can be moved over the external memory interface in one second. It's calculated by multiplying the bus width by its memory speed. If it uses DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed in one second. This is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The better this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second. Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
