Compare any two graphics cards:
GeForce GTX 850M vs Radeon HD 3650
IntroThe GeForce GTX 850M makes use of a 28 nm design. nVidia has set the core frequency at 876 MHz. The DDR3 RAM works at a frequency of 1000 MHz on this model. It features 640 SPUs as well as 40 TAUs and 16 ROPs.Compare those specifications to the Radeon HD 3650, which uses a 55 nm design. AMD has set the core speed at 725 MHz. The GDDR4 RAM runs at a frequency of 800 MHz on this specific model. It features 120(24x5) SPUs as well as 8 Texture Address Units and 4 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the GeForce GTX 850M should perform quite a bit faster than the Radeon HD 3650 overall. (explain)
Texel RateThe GeForce GTX 850M should be a lot (about 504%) faster with regards to anisotropic filtering than the Radeon HD 3650. (explain)
Pixel RateThe GeForce GTX 850M should be quite a bit (about 383%) better at anti-aliasing than the Radeon HD 3650, and also should be capable of handling higher screen resolutions without losing too much performance. (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 maximum amount of information (in units of MB per second) that can be transferred across the external memory interface in one second. It's worked out by multiplying the bus width by its memory clock speed. If it uses DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This number is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The higher the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
