Compare any two graphics cards:
GeForce GTX 860M vs Radeon HD 3850 512MB
IntroThe GeForce GTX 860M comes with a GPU clock 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 Texture Address Units, and 16 ROPs.Compare those specs to the Radeon HD 3850 512MB, which features GPU clock speed of 668 MHz, and 512 MB of GDDR3 RAM set to run at 828 MHz through a 256-bit bus. It also is comprised of 320(64x5) Stream Processors, 16 Texture Address Units, and 16 Raster Operation Units.
Display Graphs
Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the GeForce GTX 860M will be 21% quicker than the Radeon HD 3850 512MB overall, due to its greater bandwidth. (explain)
Texel RateThe GeForce GTX 860M should be much (more or less 616%) better at AF than the Radeon HD 3850 512MB. (explain)
Pixel RateThe GeForce GTX 860M will be just a bit (more or less 19%) more effective at full screen anti-aliasing than the Radeon HD 3850 512MB, and also will 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: Memory bandwidth is the maximum amount of data (measured in MB per second) that can be transferred past the external memory interface in a second. The number is calculated by multiplying the card's bus width by its memory speed. If the card has DDR type RAM, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This figure is calculated by multiplying the total texture units of the card by the core speed of the chip. The better the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
