Compare any two graphics cards:
GeForce GTX 850M vs Radeon R9 390 8G
IntroThe GeForce GTX 850M uses a 28 nm design. nVidia has clocked the core speed at 876 MHz. The DDR3 RAM works at a speed of 1000 MHz on this specific model. It features 640 SPUs as well as 40 TAUs and 16 Rasterization Operator Units.Compare those specs to the Radeon R9 390 8G, which has a clock speed of 1000 MHz and a GDDR5 memory speed of 1500 MHz. It also features a 512-bit bus, and uses a 28 nm design. It features 2560 SPUs, 160 TAUs, and 64 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe Radeon R9 390 8G should in theory be quite a bit faster than the GeForce GTX 850M overall. (explain)
Texel RateThe Radeon R9 390 8G should be quite a bit (approximately 357%) better at texture filtering than the GeForce GTX 850M. (explain)
Pixel RateThe Radeon R9 390 8G should be quite a bit (about 357%) more effective at FSAA than the GeForce GTX 850M, and also able to handle higher screen resolutions without slowing down too much. (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 maximum amount of data (measured in MB per second) that can be transferred over the external memory interface in one second. It's worked out by multiplying the card's interface width by its memory speed. In the case of DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed in one second. This 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 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 graphics card could possibly record to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output 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.
