Compare any two graphics cards:
GeForce GTX 580 3GB vs GeForce GTX 860M
IntroThe GeForce GTX 580 3GB uses a 40 nm design. nVidia has clocked the core speed at 772 MHz. The GDDR5 memory works at a frequency of 1002 MHz on this particular card. It features 512 SPUs as well as 64 TAUs and 48 ROPs.Compare those specifications to the GeForce GTX 860M, which makes use of a 28 nm design. nVidia has set the core speed at 797 MHz. The GDDR5 memory works at a speed of 1000 MHz on this card. It features 1152 SPUs along with 96 TAUs and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the GeForce GTX 580 3GB should be 201% faster than the GeForce GTX 860M overall, because of its greater bandwidth. (explain)
Texel RateThe GeForce GTX 860M is quite a bit (more or less 55%) more effective at anisotropic filtering than the GeForce GTX 580 3GB. (explain)
Pixel RateIf using lots of anti-aliasing is important to you, then the GeForce GTX 580 3GB is the winner, by far. (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 largest amount of information (in units of MB per second) that can be moved over the external memory interface in a second. It's calculated by multiplying the card's bus width by its memory clock speed. If the card has DDR RAM, it 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, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed per second. This is calculated by multiplying the total amount of texture units of the card by the core clock 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 a second. Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes 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, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
