Compare any two graphics cards:
GeForce GTX 860M vs Radeon HD 3850 1GB
IntroThe GeForce GTX 860M comes with a GPU core speed of 797 MHz, and the 4096 MB of GDDR5 RAM runs at 1000 MHz through a 128-bit bus. It also is made up of 1152 SPUs, 96 TAUs, and 16 ROPs.Compare those specifications to the Radeon HD 3850 1GB, which uses a 55 nm design. AMD has set the core frequency at 668 MHz. The GDDR3 memory runs at a frequency of 828 MHz on this particular model. It features 320(64x5) SPUs along with 16 Texture Address Units and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe GeForce GTX 860M, in theory, should perform a lot faster than the Radeon HD 3850 1GB overall. (explain)
Texel RateThe GeForce GTX 860M is quite a bit (approximately 616%) better at anisotropic filtering than the Radeon HD 3850 1GB. (explain)
Pixel RateThe GeForce GTX 860M is just a bit (approximately 19%) more effective at AA than the Radeon HD 3850 1GB, and also should be able to handle higher 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: Memory bandwidth is the largest amount of information (counted in megabytes per second) that can be moved past the external memory interface in one second. The number is calculated by multiplying the card's interface width by the speed of its memory. If the card has DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the better 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 can be applied per second. This figure is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second. Pixel Rate: Pixel rate is the most pixels the video card could possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
