Compare any two graphics cards:
GeForce GTX 850M vs Radeon R7 M265
IntroThe GeForce GTX 850M uses a 28 nm design. nVidia has set the core frequency at 876 MHz. The DDR3 RAM runs at a speed of 1000 MHz on this particular model. It features 640 SPUs along with 40 TAUs and 16 Rasterization Operator Units.Compare all of that to the Radeon R7 M265, which uses a 28 nm design. AMD has clocked the core frequency at 725 MHz. The DDR3 memory runs at a speed of 1000 MHz on this card. It features 384 SPUs as well as 24 TAUs and 8 ROPs.

Power Usage and Theoretical BenchmarksMemory BandwidthBoth cards have exactly the same memory bandwidth, so theoretically they should have the same performance. (explain)
Texel RateThe GeForce GTX 850M is a lot (more or less 101%) faster with regards to AF than the Radeon R7 M265. (explain)
Pixel RateIf running with a high screen resolution is important to you, then the GeForce GTX 850M is the winner, by a large margin. (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 largest amount of data (counted in MB per second) that can be moved over the external memory interface in one second. It's calculated by multiplying the card's interface width by its memory clock speed. If the card has DDR type memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed in one second. This figure is calculated 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 video 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 the video card could possibly write to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of ROPs by the the core 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 rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
